The King of Random Video Idea: Freeze dry cheese and butter. What will happen?
I have noo clue
Hi
It will die
Errr........
....................
I have an explanation for the co2 and o2 jars:
for the CO2 jar :even though plants do produce more oxygen and absorb carvon dioxide to make glucose plants also NEED oxygen as like us they do cellular respiration. Since there was not enough oxygen for them to essentially breathe, the cells in the plant died. And I think that bcos the cells died, the chlorophyll in the cells which gives plants the green colour died and it got decoloured.
For the oxgen container: even though there was no carbon dioxide for the plants to absorb and make glucose which is essentially their food, plants actually store their excess glucose in the stems and other parts of the plant in the form of starch(edit) so since it still had oxygen to breathe the cells did not die and the plant was living on its food storage from the glucose it had produced prior to the experiment
TLDR: CO2 is for food and O2 is for breathing and like humans, plants can survive longer without food than without breath.
Right! Just wanted to comment the same thing
I was wondering if anyone was gonna mention this, cause just from the moment they said they were testing CO2 and O2 I realized what was going to happen. Can confirm. Plants need oxygen too.
Not glycogen. Glucose is stored as either starch or cellulose, with the latter having mostly a structural role, while the former are the actual energy reserves.
Glycogen composes animal reserves.
Couldn't have explained it better myself lol... I was yelling at the screen as he was filling the CO2 and badmouthing the O2😂
Well by breathing oxygen it also produced some CO2 for itself
Actually plants do "breathe" O2 during the night when they can't do photosynthesis. That's why you can put a plant with the right amount of water into a jar/container and have it sealed with the plant still surviving.
Also the reason why the nearly pure CO2 turned bad and the O2 one not might be that mold grows in anaerobic environments as seen in another TKOR video where they put different food items in a sealed vacuum to test if they would turn stale/moldy which to no surprise did happen to much of the food.
Another reason could be that because of the high CO2 content some of the CO2 dissolved into the water and made it more acidic which is probably not the best growing condition for basil.
is that why the O2 plant lived while CO2 died?
@@boa_firebrand yes i assume thats one of the reasons besides the ones I edited to my previous comment

Some comments are made to go to the top. This is one of them
I have a thought/challenge for you guys. I remember being taught once that when a bean or seed sprouts and sends out it's first roots and shoots, gravity determines which direction they grow, ie the plant "knows" to send the root down towards gravity and the shoot up away from it. SO, that being said, what would happen to the emerging plant to be if its orientation to gravity kept changing, like if it was constantly being rotated slowly- how would THAT affect its growth at all?
culthosmythos spiral plant!!!
Plants were sent up to the ISS to see how microgravity effects plant growth. I think you can find it on CZcams!
Everyone like this so they will see it
Nice idea, I think you can get a clear gel for starting seeds/cuttings, if a bean was grown in this medium it would work well and you would see the results clearly,
I would like to see 4 or 5 beans sprouting whilst being spun at different speeds, timelapse would be nice too

There's a pretty common misconception about plants, they do breath as well as make photosynthesis, so they need oxygen to live. Microorganisms on the soil already produce CO2 as well, so...
Those organisms produce oxygen for the roots. Co2 is for the plant body
I don't understand but here's a like 👍
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👎👍👍👍
Michorrizae is what theyre called. Very beneficial for roots
@@Secr3tYT Idk where you got that piece of information from, but nothing produces oxygen for the roots (other than the plants themselves, if the process of photosynthesis contributes any). The oxygen diffuses into the soil from the atmosphere and get absorbed by plants and micro organisms. In fact, the soil is one of the major natural CO2 producer in the carbon cycle. Moreover, if you submerge soil samples under water, then they will quickly become an oxygen-poor environment, thus micro organisms have to harvest energy from less energetic oxidation reactions, eventually ending up with a reductive environment that produces gases like methane.
Plants need oxygen to break down glucose. They can’t survive in an environment without oxygen. Thank you High school biology.
they need carbon dioxide
The plants can use photosynthesis to convert the co2 into oxygen as well as obtain glucose for respiration, so the problem shouldn’t be a lack of O2.
@@janiexiong4560 yes they need co2 for photosynthesis to create sugars, but they need o2 to break the sugars down for energy. It's very much more complicated than it looks.
@@janiexiong4560 it is though plants need oxygen and CO2
My observations as a farmer: the open control obviously lost water to evaporation so that's why it wilted. The open bottle could "breathe" but had less evaporation and a higher humidity around the stem and in the bottle. Plants does well in a humid hot humidity, but so does fungus. In a cool and humid environment you can lose entire crops to funguses. The bottle with the higher oxygen content didn't surprise me either - plants breathe oxygen through the day and if you left the light on 24/7... Furthermore the fact that the CO2 plant smelled like "old grass" didn't surprise me either. Funguses can't grow in a environment with no oxygen so farmers are always using it as a trick to turn grass and corn into silage. The vacuum is also a no brainer - question is why didn't you test a plant in a pressurized environment?
Close, but backwards. Plants take in CO2 through the day and use the light energy to turn it into carbohydrates. At night they give off CO2 and water.
Great question
Also: vacuum plant lost moisture due to boiling point dropping so low, causing cell death throughout.
The vacuum probably ripped the plant cells apart as well
Depends how strong the vacuum was. If it was a total vacuum the plant would have completely dried out. It seems like in the test it was pretty weak and the water evaporating likely would have returned it close to normal atmosphere after awhile.
@@Jake12220 yea the vacuum shouldnt be to bad for the amount of water if you have ever tried removing it even at like 10 mbar it takes heats of like 50 C to go at a decent rate and as you said it is a close system
Plants don’t breathe CO2; a closer analogy would be to say that they “eat” it.
All complex life that we know of performs respiration by absorbing oxygen and expelling CO2, even plants.
Dont forget about algae, not so complex.
Vic 1 Yeah, but I needed some qualifier to exclude anaerobes.
Cyrus Antony It isn’t a perfect analogy, but it’s closer than breathing.
The energy comes from the sun; the material comes from the carbon dioxide (CO2) and water (H2O). The plant combines the carbon and the hydrogen (and some of the oxygen) to form carbohydrates and then expel the remaining oxygen.
Maybe a better comparison would be herbs, spices, and condiments. It’s not necessarily nourishing, but it makes the food edible.
They have recently found a parasitic jellyfish that does not use respire using oxygen. I'm not trying to contradict your argument as it is the only known exception but I just thought it might be interesting to you.
More like... They cook using co2.

At night many plants will “eat” oxygen and put out CO2, so it makes somewhat sense why the sealed oxygen did better then the sealed CO2
That Onion, even if plant consume co2 throughout photosynthesis, they still need some oxygen.
@@ThatOnionispog actually:
During daytime, photosynthesis is going on faster than respiration, so, normally, plants will produce oxygen during the day. However, at night, only respiration continues, so plants (like other organisms - mice - cats - dogs - people - bacteria) produce carbon dioxide and use up oxygen.
@@ThatOnionispog imagine not paying attention in class
Only during photosynthesis it takes in carbon dioxide to make food nd oxygen to breath at other times it uses oxygen as normal living things
not eat, plants literally breathe, they use most of the o3 they produce
*sees poor basil plants not used for cooking*
[screams in Italian]
Lol
I have a degree in plant science and I can shed some light on why the CO2 plant died and the Oxygen plant did just fine. Basically plants still need oxygen. Yes plants use CO2 + Sunlight to make sugars to store the energy of the sun for later and oxygen is a by product here. The important part is that in order to release and harness the energy stored in the sugar they need to use oxygen in the process, creating water and CO2 again. So it's theoretically a closed loop, but in actuality the plant needs both Water and Oxygen and CO2 to be supplied to it in order to thrive in the long run. Reason being that all the pieces need to come together at the right time, all of them need to be plentiful enough to randomly interact in the chaotic mess that is the life of a cell.
It's a fine tuned process that has been evolved over millions or billions of years so it is especially adapted to deal with the concentrations similar to those found in nature. In nature O2 makes up ~20% of the atmosphere where as CO2 is 410 parts per million or 0.041% so the plant is going to be a lot more sensitive to the oxygen level going to 0 than the CO2.
Another way to think about it is taking away the CO2 stops the plant from storing new energy while taking away all the O2 takes away its ability to release any of its stored energy so it doesn't matter how much more energy it can store with all that CO2 available.
Final point here, the marginal amount of CO2 released in the process of the plant breaking down its sugars would be much more significant to the plant because it is used to such low levels. Comparatively the marginal amount of O2 released in photosynthesis is going to seem like nothing when the plant is used to a 20% O2 atmosphere.
Forgetting H2O for the photosynthesis
It may have also undergone photorespiration from the excess oxygen causing rubisco to fixate oxygen and output CO2. So the oxygen plant was probably just slowly dying and while the root system was doing just fine.
ive never heard about anyone with a degree in plant science until now
XD bc it isn't a thing it has a different name or may just be a biologist
@@kenobi94 what you mean? Plant science is a real degree. It may not be something you've heard of but it's still a thing
5:50 What most likely happened is that the “control” was set inside a mason jar where humidity was able to concentrate creating a perfect environment for mold to grow. This is exactly why you did not get the same results with the plant that was left out in the the open or the ones that where closed and/or vacuumed. Most fungi and mold need air and humidity to grow. Of course the spores were already in the environment and/or in the plant before you started. You just gave it the perfect environment to thrive. Hope this was helpful.
@@wesleybrame6846 the jar keeps the humidity better
And then the gasses to yes
Prime Shadow because the closed jar keeps in the moisture
@@wesleybrame6846 CO2 woulda suffocated any mold
Yeah I think they know already....
The co2 around the plant can, in a way, “burn” it. The oxygen kind of acts as an air conditioner. That’s why the sealed co2 one didn’t do well.
co2 is acidic after all
and plant ned more oxygen then co2
There is only 400 in a million parts of co2 in the air so it was 200 time more co2
Yes after all co2 does trap alot of heat and is slightly acidic
No. And no to all the replies also. It's really quite simple. Plants breath just like you and me. They take in oxygen and consum it with sugar to grow and stay alive. The byproduct of this is co2 just like you. Plants only make more oxygen than they consume during the day when sunlight can power photosynthesis. That's why everyone saying that the Amazon creates most of the breathable air is demonstratively wrong. The Amazon is oxygen neutral. At night, the plants and animals consume all the extra oxygen produced during the day. Earth's primary oxygen supply comes from diatoms in the ocean.

6:41 because plant didn't need CO2 to breath, they need O2 to breath.
Plant using CO2 as one of the ingredients for them to make food (carbohydrate), not for breathing.
You guys need to test the effects of temprsrily placing large neodymium iron-boron magnet (N45), 2"x2"×1", South side facing the root of the plants. Wrap the magnet in cellophane wrap to protect the magent plating from leaching into the soil. Remove the magnet at the end of the growing season. Veggie/ fruit plants that have a magnet placed below their root system loke this will grow bigger and healthier.

Justin: kinda like the banana peel and the rose bush?
Too much water, probably fungus gnats, and fungal spores from the air either in the lab or from where you got them could be contributing factors to the health of plants.
The pure CO2 one suffocated the roots of the plant and the aerobic bacteria and fungi, acidified the soil, and decreased the ability of the plant to use water. The pure O2 allows the roots to breathe and gave the cells enough fuel for respiration (burning stored energy, like animal cells) which may temporarily make up for the lack of photosynthesis, plants are massive carbohydrate/sugar stores afterall. But the pure O2 is probably more reliably explained by creating an atmosphere that's great for the roots and the aerobic bacteria and fungi present in the soil, which then produce carbon dioxide and other nutrients for the plant to use to grow.
Exactly Correct. Need more thumbs.
Part of the issue is that herbs don't like wet roots. The sealed containers held onto too much water
Its a common misconception, plants only use c02 when actively photosynthesizing, at night they switch to using o2.
without o2 they sufficate, without co2 they just cant grow larger

I actually did a similar experiment in middle school and used ammonia (cleaning liquid in a dish), carbon monoxide (exhaust from a car), and chlorine (bleach in a dish) as additives to the sealed atmosphere in an aquarium. Oddly enough, the chlorine exposures (I had three plants for each trial) did the best, even better than the control.

this is the same comment you made on another video
As a landscaper I just thought of this:
Infusing some piece of land with liquid nitrogen and seeing how well a plant in that area does
Temperature and pressure difference would just result in the nitrogen turning into a gas and returning to the atmosphere. Also plants use Nitrate NO3 not N2. N2 is very unreactive. This is why legume are called 'nitrogen fixing' they take N2 and through a complicated process convert it into NH3. Then bacteria can turn that into NH4, then other bacteria turn that into NO3 and other bacteria turn it into NO3 which plants can use.
The other method of nitrogen getting into the soil is from animal urine and feces and decomposers of dead plants.
So in effect, other then largely sterilizing the soil for a short term due to the thermal shock and lack of O2 nothing would happen.
@@Cragified "N2 is very unreactive. " Now here is an understatement and a half ;)
Plants don’t “breath” CO2. They use it as a precursor to the photosynthetic process to generate carbohydrates. Technically they do breathe oxygen as part of cellular respiration. It just so happens that oxygen is also a byproduct of photosynthesis.
Do more plant video's . It's very interesting!✌🏼
The Oxygen plant seems to show that maybe the Oxygen theory is correct for why plants grew so big in prehistoric times.
Nope
Plants need oxygen to produce energy. They only need need CO2 to create food, mostly carbohydrates. Like human, plants can survive longer with no food than they could with no oxygen. It can't survive long enough to turn that CO2 into oxygen.

If there's no drainage fungus will form. For jars(anything with a closed bottom) you have to create a drainage layer to prevent fungus.
This takes primary school science experiments to the next level.
The O2 sealed plant is acting like an unbalanced terrarium where the microbes/ little bugs in the soil use the oxygen to breathe and then exhale CO2 for the plant to convert to O2 over and over again.

The mould on your open control is called botrytis. It's a greyish mould caused, normally by dampness.
Basil is actually very prone to it. My family owned a garden centre in the Uk and overwinter or a particularly wet and cold summer we'd lose a lot of our basil plant to it. It's caused by damp air and cold or watering late in the day when it's cold overnight. The best way to prevent it is to water the plant's first thing in the morning so they have all day to dry off and keep them somewhere warmer overnight (if memory serves me correct above 10°C.)

What about a test of different types of rooting methods/powders? Rooting being the trimming and replanting of plants to create more plants-give them away as gifts, make your garden bigger.
Rooting can be done with simple vegetables-like onions and radish-by sticking the root or leafy portion into water for a few days.
But with fruit trees or other plants, rooting can be more difficult, and so they have powders that you can use to sterilize the soil (prevent rotting) and promote root growth on the cut branches. You can use purchased rooting powder, as well as a variety of other methods like honey, cinnamon, aspirins tablets, etc.
Next: Will a human thrive in an oxygen only environment
Or a CO2 only environment. But first, we are going to need bigger jars and vacuum....
Ironically, a completely oxygen environment would actually suffocate you.
It depends on the pressure. If the O2 partial pressure is too high, O2 becomes toxic - it will cause seizures and retinopathy, among other bad things. I don't remember the charts (you study this stuff when learning about O2-enriched mixtures for diving, called a "nitrox" blend), but I think 100% pure O2 at sea level pressure is pretty close to, if not above, the oxygen toxicity level. It's also a function of time as well as pressure, so the longer you spend in a hyperoxic environment, the closer you get to oxygen poisoning.
Fun fact - diving below 184 feet on regular air will result in oxygen toxicity, because at that depth the gas pressure is enough to increase the O2 partial pressure past the toxicity limit. At that depth, you have to use a hypoxic mixture (less than 21% O2), such as a trimix (air + Helium).
@@drdrums1 02 actually isn't toxic until much deeper, but for recreational diving, there isn't any reason to put yourself at risk. On 32% nitrox you don't usually want to go below ~110 feet.

The most concentrated one 😉
They did in Brazil! Check Manual do Mundo
Although plants DO use CO2 for photosynthesis, it does not go directly to energy. Photosynthesis merely creates glucose, which is basically food. On order to turn that glucose into ATP (energy), it needs oxygen for cellular respiration. In all, you generally need significantly less CO2 than oxygen, because actually being able to use food is better than just having it.

Actually plants also breath like us. Plants can do photosynthesis, where they use water and CO2 to produce O2. But they can also do the opposite, use the oxygen to survive, usually this breathing process is something that plant do during the night.
The reason that the oxygen one grew so much was because of the mitochondria being able to make more energy therefore making it grow more. Even though CO2 is also important I guess oxygen is too.
Little correction: Plants need both, CO2 and Oxygen but more CO2 than Oxygen. At day they consume CO2 and at night they consume O2. That has to do with missing sunlight at night so they can not do photosynthesis but when they do "breath" they can live without it.
That's what I learned in school
Plants take in O2 all the time for aerobic respiration but they only take in CO2 in the day as it is needed in photosynthesis along with water and sunlight

Next week on The King of Random:
One celled organisms in a vacuum.
Would love to see one of those sealed habitat plant things done. I've seen them all over the place. It's like a mini eco system. Would be fun to play with different factors in the sealed ecosystem.
I have a degree in plant science, hard to say about the mold in the control jar. Completely possible that it(the mold) just enjoyed the elevated humidity from the moist soil + less airflow into the jar compared to a natural setting.
No soil is gonna be sterile and plant are constantly fighting fungi so it could just be random chance the fungi in the soil or spores landing on it just happened to be something it couldn't face, or it could be that something about the experimental condition tilted the battle in favor of the fungus
So about the plant sealed in the oxygen jar: plants can do cellular respiration as well, so is that why it's still relatively functional?
think of carbon dioxide as food and oxygen as just air, thats why the oxygen one did slightly better than the co2 one
exactly right it probasbly just had food stored up in the form of starch and was able to convert it into energy using the oxygen. The plant in the CO2 could make more food but it couldn't use the food that it made.
Cool that you do the old fashion tkr i realy appriciate

0:26 he should’ve said what happens if I lick the plant 🤪
For those pondering the one in the vacuum. Plants utilize water to do the job our blood does. At the leaves there are very small openings just large enough for water molecules to evaporate from. This causes a negative pressure (possible in liquids) that pulls water up the plant bringing sugars and minerals up to the leaves. When you put it into a vacuum the water in the soil undergo a phase change into a gas. So the jar was actually filled with water vapor (Hence the water droplets on the inside of the jar) because of this and the conditions it was then impossible for water to evaporate from the leaves and 'pump' up sugars and nutrients since the water vapor atmosphere within was already at its maximum pressure.
Having researched a bit of hydroponics and aeroponics,
1) Plants definitely need oxygen and that’s one of the reasons aeroponics and hydroponics with aeration into the nutrient solution works as effectively as it does: oxygen availability to the roots.
2) Earth’s base atmosphere is ~20% oxygen whereas CO2 exists in very small amounts relatively.
3) When you’re smelling the sealed jars, you’re not smelling only your test basil plant but any and all soil bacteria that was also trapped into the environment with the plant during your test period. Aerobic bacteria growth vs anaerobic bacteria growth (or suppression/absence) are affected by the sealed environments as well.
(Also, sealing and temp affects things like humidity, which definitely affects plant growth and would be much more difficult to control for.)

NO! NO! NO!

Plats can use O2 to breath if they can't photosynthesis
They ALWAYS breath O2. Not just at night or something. Assimilation/dissimilation

So in today’s video we are taking away the main necessity the human needs and locking it away in a jar :D
If you guys plan on doing experiments like this again, I suggest using something like duckweed since it’s small and has fewer requirements, eliminating some of the factors that effected your Basil
You guys should get several meals from fast food restaurants and let them sit out for a while and see what happens. Love the show guys!

You guys should do some vacuum experiments involving the boiling point of water. Vacuum 33 degree water and some ice and whatever else goes with that idea.
