- Many plants produce crystals in their cells. The function is not always understood but might be for protection or to store waste products. These cells are called idioblasts and the crystals are often made of calcium oxalate.

oh waaw, MH: this is the nicest thing i've seen. you have 'outshined' yourself again. loooooove these colours. i still have so much to learn! thank you
How wonderful structures and crystal color. And thank you so much for this detailled and scientific explanation of the special metabolism. How exciting to see the results inside the plants 👍
Nicely filmed and narrated. I like these sort of featurettes that you do. It's okay if they are longer. But please no shorter. ;) I thoroughly dislike CZcams shorts. Anything worth doing is surely worth more than 15 seconds.
aus den Schnitten geht hervor dass diese astroyztischen Ideoblasten auch eine Stuetzfunktion haben koennten. Die Calziumoxalat-ablagerungen koennten dann im Zusammenhang mit dem Umbau der Zellwaende zu tun haben. Eine Speicherfunktion der Zelle fuer Calcium wird auch diskutiert.
Amazing .
Thanks for all the knowledge you share on your channel! Is it possible to yield the same results (the color/lighting of the specimen) with the Swift SW200DL introductory microscope?
This is not fully possible, unfortunately. A microscope with a condenser will give you more possibilities (like darkfield etc). But there is something that I would try, what would work. You can buy some plastic polarization filter on Amazon and put one right below the slide and the other one right on top of the slide (between slide and objective). Rotate the top filter and you will also get some nice results. Try this first with potato starch grains (scratch surface of potato). For example: czcams.com/video/rQPPWXxCBX4/video.html or czcams.com/video/Tlca5UIzPuE/video.html
@@Microbehunter thanks, I will try that. Because of you, I purchased a SW200DL type microscope for myself as well as one for my 6 year old niece. I live in Houston , Texas and she is in Louisiana. My goal is to zoom with her and we share our findings as well as we swap samples from our regions. I have been so amazed at what I can observe under a
wenn diese Ideoblasten eine exkretorische Funktion haetten, dann waeren sie nach aussen und nicht nach innen gerichtet. Sie haben nicht einmal eine sekretorische Funktion da die Ca-oxalate innerhalb der Zellmembran zu liegen scheinen und nicht vom Ideoblasten abgegen sind.
care wollastone prisme is not nessesary for changing the color in POL. A simple lamda-4 or -2 plate made from mica does the job
Mikroskop adı nedir.
Teşekkürler
this asterocytic ideoblasts can also repell some intruders in the aerenchym. Why only this waterplants have an excess of Calziumoxalat and other plants not, could you please explain this......
❤❤❤
Hi ' please I need learn how prapare permenant slide for algae for identification and I need learn the basic points that dependent on them for classification and numeration the algae
Algae can be mounted in a water-based mounting medium such as glycerine gelatin (glycerol jelly). I have also mounted them in Elmers clear PVA glue, which is also water-based. For identification, there are many of them and it depends on what detail you want to identify them. This here is a starting point: wcwc.ca/wp-content/uploads/2020/12/Algae-identification-lab-guide.pdf

I've seen a couple of videos of yours about whether microorganisms are intelligent.
I would personally define intelligence as behaviour that demonstrates something is under intelligent control. This can be via coding eg heat seeking missile (intelligence involved but via an intelligent agent coding). But it is where perception capacity and motility capacity via physiological means coexist that it evidences intelligence of a non human created nature.
The definition is irrelevant though. Whether someone classifies goal directed non random motility as intelligence or not, the phenomenon still needs an explanation in terms of ultimate cause.
Imagine a leaf in the wind. For several seconds it may falsely appear to have agency and be mistaken for, say, a butterfly. But it would soon be apparent its movement is purely governed by external forces. Convection, fluid flow eg a river, magnetism, gravity, wind, chemical gradients etc can all cause movement. However, none of these would give us true "under intelligent control" behaviour.
The issue is: how can a random movement eg via a proto flagella suddenly hit non random such that the enhanced fitness can be perpetuated through heritability? Randomly hitting upon a food source may be advantageous but the luck factor is not heritable. And the "under intelligent control" behaviour we observe (with no CNS) is not illusory nor just infinite random movements happening to mimic goal direction. It would seem impossible (not only statistically impossible) for this to arise via random mutations etc.
The only explanation I can see is that the potentiality was fundamental and evolution's involvement is in the production of the physiology to facilitate it. Similar in a way to qualia, where physical manifestations evolve that hone in on the experiences that HAD to be a potentiality (if it wasn't a potentiality then it could never arise even through emergence).
I just cannot see how "under intelligent control" can arise via a skyhook / picking itself up by its own bootstraps.
Why is it important? The natural state would be that "under intelligent control" should never occur without mind. It isn't that it only appears to emulate mind. How can there be a transition from random otherwise because, other than accepting certain fundamental forces that cause movement as axiomatic eg gravity (which itself is in need of an ultimate cause explanation), the whole point of infinite non random goal oriented behaviour is that it indicates a phenomenon that just cannot occur by chance. It is literally impossible without there being a kind of force (mind) that differs from non random or basic external forces based movement.
Many biologists are so hypnotised by natural selection that they assume "oh, it is highly beneficial to have goal directed motility and so it evolved" ie as if evolution can harness the non random goal oriented capacity; yet evolution does not have the power to bring about this transition. It has to be a latent capacity.
The big issue with methodological naturalism is it causes most scientists to avoid following the evidence as it makes a huge assumption that there cannot be fundamental consciousness/intelligence/Source etc.
There are countless other pieces of evidence that there is fundamental consciousness but I'm really keen to see if there is a way the transition described can arise without there being fundamental intelligence. As mentioned, the transition from random movement (or via external forces) is a far cry from "under intelligent control".
I will post this under the appropriate video you made to see if it attracts comments off informed viewers also ;)
Best wishes
can a polarising microscope do this if i learn how to use it, and have it fixed first? wild 21 swiss made. your fault: after the soya crystal thing 😂
While I do use polarized light, the setup is different. I have "DIC", which is also able to change the background color by shifting a prism. But by placing a sample between two polarizing filters, you should also get some beautiful effects. The filters are cheap. Polarization microscope not needed.
Are CPL filters ok or is it mandatory to use linear polarization? @@Microbehunter
The matter is, CPL glass filters offer a predictable optical path... flat and of known thickness while the typical cheap plastic linear polarizer simply doesn't offer the same. And high quality linear polarizers are quite more difficult to source. Thank you in advance!
@@inverse2k1 Might work, you have to check that the orientation is such that there is complete extinction of the light. I have tried CPL filters from paper 3D glasses (flexible) and they worked. To my knowledge, there are also different standards available (RealD etc). For all practical purposes, and simple observation (without measurements), I found the plastic ones to work well, because the actual area that one looks at is quite small and any deformations of the plastic will not be visible well.
