Angiosperms: Flowering Plants
Vložit
- čas přidán 3. 12. 2020
- We just learned about gymnosperms, and the incredible evolutionary advantages they had over their ancestors. But the next leap forward for plants was even more impressive. Angiosperms are flowering plants, so any plant with flowers or fruits is an angiosperm. And instead of fertilizing by wind, angiosperms enlist the help of animals to execute highly targeted fertilization for them, affording them even more reproductive success, which is why angiosperms quickly covered the world. Let's learn more about angiosperm variety, reproduction, and other details.

CZcams has done you dirty 1 million subs and only 1.7k views I’m sorry thanks for teaching us
not everything is about likes and views bro
Look again
1 million subs and still less than 1k views man? You deserve better
Not everyone is into trees I guess!
@@ProfessorDaveExplainsawww🥺🥺
Another great piece in a lengthy line of discussions on plants. Well done, Professor Dave. I'm no biologist or botanist, but I feel much better armed to hold a conversation with friends of mine who are. Thanks for work you're putting in on this and other series.
This really helped me a lot, all thanks to you professor.
Really enjoyed and understood this video and all the concepts talked about
Thank you, very interesting and easy to understand
Thanks for your videos. You taught me chemistry and now biology 2.
Hey man ur the best!! don’t ever stop making vids I always look for professor dave before anyone else like khan academy or organic chem tutor 😎👍🏼
Organic chemistry tutor teach's Biology
Thanks...you're the best among all
This so helpful, I enjoyed it🔥🔥🔥🔥
I have a question about two gymnosperm types: is there any reason why in northern latitudes they are like coniferous and in tropical regions like palm trees?
Thank You prof it help me a lot in explaining this in my students
Great explanation sir 🤩🤗
What a nice voice u have professor!! Professional ❤️❤️
thanks professor
Beautiful ☀️
I have a plant and soil degree and i still get the names of the flower parts confused
I've always had trouble remembering the difference between the term carpel and the term pistil
Haha. I also find it hard to recall each time. But I guess I know finally what gymnos and angios are.
Very nice
Professor dave
Explain about subclasses of stars
(A0 A1 A2 A3) and how to individuate and plot them
Please discuss about inflorescence 😊
Nice
2:22 I had no idea a moth has such a long tongue. I've never seen a moth's tongue. I've "grown" a few moths though.
does this mean that there can be another evolution after angiosperms that deploy more efficient methods? that would be incredible but probably wont happen in our lives
🙏 got this exam in the bag
Prof dave
Thank U sooo mch
And I love you so much where have you been just wanted to see you not hear from U😢😷
It’s videos like these that make me regret dropping out of my biology major ; (
You do so many new videos I wonder when you find time to sleep.
Thank you for your videos! One thing though, there are far more than 250.000 flowering plants - actually 369.000 flowering plants are know by science! (State of the World's Plants)
Mmmh.... flowering plants...
Đẹp lắm bạn ơi ♥️👍👋
Sir, what's the reason behind #tattoo on your left hand?😊

Angiosperms brought out the botany of desire in humans. Read the Botany of Desireby Michael Pollan. Its an interesting look into the coevolution between angiosperms and humans.
Intro to adaptive immunity?
soon
@@ProfessorDaveExplains you also forgot a video on monocytes, they are another important cellular aspect in the innate immunity and more than macrophage dc transformers
2:35 The male gymnosperm cone is usually smaller than the female cone I think.
Nono femal is small and fat ig
Professor dave what about the gymnosperm gnetum (gnetophyta). They posses a less advanced version of double fertilization, oval shape leaves, a seed wall similar to a fruit. They also posses some xylem tissues only angiosperms posses. Yet they don't have flowers. However DNA and molecular studies don't add up with the theme. What do you think about angiosperm relation to gnetophytes. Could they be a failed attempt by natural selection to posses the fruit? Gnetophytes onces dominated the world during jurassic but not anymore. Is it because anthophytes did what gnetophytes failed?
What is the theme song saying? He know a lot about the science _____?
stuff!
@@ProfessorDaveExplains Of course! Thanks for the botany lessons.
Gymnosperms do not technically make flowers; otherwise this is a great video!
Fruits flowers pollination and honey…./
A doubt ~~ how can the just chemically conscious organisms that is plants know that there are some bees, birds, animals roaming around the world so we should evolve like this (case of angiosperms)
DNA can mutate but how it got commanded...for that big purpose??
Evolution by natural selection is just random chance and statistical dynamics.
Sir....Plz...explain the black hole theory 📖

Have you ever thought about doing a “Destroying Flat-Earthers without science part 4? They seem to be very popular.
i may do just one more
I. LOVE YOU ❤😊😅😢😮😂❤
I’m late
how lost your hair?
First view
Wow
Fruits flowers pollination ahd honey……………………………vegetables……..
First!
Imagine using plants as money. 🌱🤑
we are already using trees

Hey Dave have you seen Dr. Robitaille's paper in Physical Chemistry Chemical Physics ? I think you should take back your hate video and apologize to him
I think you should stop posting on unrelated botany videos and actually watch my debunk of him so that you can stop embarrassing yourself on the internet.
" I think you should take back your hate video and apologize to him"
I think you should fuck off.
I'm unilaterally declaring myself the winner of this important debate. Now apologize to me for wasting my time.
It wasn't a hate video in the slightest. Dave provided a mountain of very clear concrete evidence that Pierre says things that are objectively incorrect. Calling out liars like Pierre appropriate and necessary. Really, given the circumstances Dave was super nice. What Pierre does is truly despicable, telling crazy lies and misleading thousand of gullible people.
if something is indeed real then it can be reproduced or proven in a lab test yes? so how does water curve around a ball? water is the perfect level, builders have been using this method for years as it works the best to get perfectly flat, level measurements and yet we are told water wraps around the globe, a ball, it curves?????? can you please show me this in a lab test, water curving 360 degrees in every angle, water curving and comforting to the ball, not dripping down or running off.
if it is true then it will be easy to do!!!! thanks, looking forward to this video.
Buddy, you're a little lost. This is a science tutorial. You know, for people who are interested in learning science? Stick to your echo chamber of delusional children. Or visit my physics tutorials when you get tired of being so unbelievably clueless.
@@ProfessorDaveExplains why do people fire off insults as a first reply? I asked a science based question, I inferred nothing either way, you presume too much. your rude response only makes me think I hit a nerve that you seems to be struggling with yourself........oh well I was hoping for a real answer but I guess I was expecting too much.
I don't "presume" anything. You're a flat earther, which makes you among the dumbest people alive. I debunked this and every other idiotic thing you've ever said or thought about the shape of the earth in my several flat earth debunks. Sack up and watch them, kiddo.
Mergatroid, to answer your question, the reason why water sticks to the earth is because it is massive and therefore has a lot of gravity. The more mass an object is, the more gravity it has. For something to have that much gravity it must be pretty big, such as a planet, moon, or large asteroid. Have you ever seen a laboratory be enough to fit a moon inside of it? That would be a pretty big laboratory! But you can tell the earth is round just from your own observation, for instance by looking at a moonrise or a moonset. Seriously look at the moon when it is rising or setting as it appears to cross the ocean or a mountain, you should have no doubt. If the earth was flat the moonrise/moonset would not look that way. Same with the sunrise/sunset but I'm afraid that if I tell you to go look at the sunrise or sunset you might accidentally go blind, so be careful if you try that. Dave's channel here has a number of excellent flat earth debunks. My personal favorite is "Destroying flat earth without using science part 2 the stars." Watch that and you will know that without a shadow of a doubt the earth is round. Just think, in only five minutes and twenty-four seconds from now you can be free of your delusions. After you have watched all of Dave's flat earth debunks, sci man dan's flat earth friday playlist is pretty fun too. Have a nice day.

Hi Dave. i was wondering if you googled “What is the percentage of black children born in wedlock in 2020?” yet ?
And then search, “What was the percentage of black children born in wedlock in the 1920s?” Followed by, “what was the percentage of black children born in wedlock in the 1950s / 1960s etc”
Compare the 3 percentages and you’ll see it go from 20% to as high as 72% today! it’s amazin’!
If you have not or can not find the data, let me know, and i will send you some verified sources.
I do want to say that I understand why you did not know that the stuff Jesse said in your debate was true. Our generation was truly brainwashed. And the reason our generation imediately shuts down what he says, is because we have been lied to for so long so it’s hard for us to fathom the truth. It’s amazin’!
One thing that people in our generation should do to understand the truth more, is to get out and travel around the world. And when we do that, we see that we have been lied to about a lot of stuff growing up. The first time i heard Jesse speak, i was amazed and thought “What The!? Is this guy being silly!?!?” but then i did the research, real research, and everything he says is right.. Just like how we were told that whites enslaved blacks, but we were never told that slavery had been around forever! And that blacks sold blacks! And blacks owned Blacks! it’s amazing!
I think what you guys are trying to say is: jesse says it wasn’t racist back then because it was more so just the current reality, not racism.. however, if this were to happen today, yes dave would be correct that it’s racist.. but we need to understand the norm was different and has changed.
The same goes with you not understanding what he says about women loving their children and anger. you don’t understand because you are an atheist. which is okay. but when you are born again, you don’t need to be shown because you just KNOW
and you find out that everything you’ve ever needed to know, you already know! but until you apologize to your mother for hating her for taking you away from your father mentally and sometimes physically, forgive her, and forgive your father, only then will you be born again and everything that you already know but couldn’t see - comes to light! but until you have this happen, it sounds silly and sounds like fantasy land but i promise you it’s true..
Also re watch your debate and you’ll see how angry you became, but you’ll see Jesse didn’t get angry at all. But it’s okay because it’s not your fault.
But anywho. I enjoy your other videos! keep up the good work! Have a nice day!!
roflmao!
Chris, out of wedlock does not mean single. Jesse distorts statistics to match a narrative he has created. He's a moron and a pawn for conservatives to pretend that it's ok to hate black people. Literally nothing he says is true. It doesn't matter how many past incarnations of slavery there were. In America, white people enslaved black people. When one race enslaves another, it's racist. Anyone who says otherwise is a moron. For Jesse to say racism doesn't exist is disgusting. And the part about women not loving their children? I'm sorry, but if you don't recognize right there that he's an idiot, that's on you. It's astounding that anyone gives him five seconds of their attention. I've never interacted with a dumber person. And no, I objectively didn't get angry, I was literally laughing the whole time. You've invented an alternate reality. It's pathetic.
"Also re watch your debate and you’ll see how angry you became"
ah, another moron who thinks righteous anger means "you lost."
no doubt if I tell this person to fuck off, surely that means "I lost".
