Sclerenchyma is the most made-up sounding term I've ever heard. Loving your videos Dave. I came for the physics but I don't know this stuff at all so it's great, thank you.
Thank you very much for providing such a diverse array of educational materials. We've recently started linking your channel in the description on one of our science Saturday let's plays because we want our younger viewers to come to your channel. We hope it helps you educate some folks!
To be fair... Those eps won't show up for a couple months but your link WILL be in every description for that game! The game name is Odyssey: The Invention Of Science! Keep your eyes out if you're interested in that sort of thing! One of the first thing it tackles is flat earth, which we feel you'd appreciate given the recent stuff you've done on flat earthers xD
Yay! This will be most helpful for teaching the hydro store employees and customers near me! I have a terrible case of the rambles and I often get lost on a tangent. I shall be telling people about this video!
In regards to the root/shoot growth; are the meristematic cells geotropic? Positive or negative in relation to where they are used, either the roots or the shoots.
today I went into a woodlot and analyzed some plant leaves. darker leaves contain more clorophyll and are more adapted to shadowy areas. >Other cool facts in addition. Like leaf albedo. Prof. Dave should make a vid on it ! ;)
Hi! I really learned a lot from this ^^ I'd like to ask if you have videos about trichomes? We had an activity about it and I haven't found any information that I was searching for.
Hello. One of your biggest fans (like everyone else). Do you have a website that would perhaps have better organization fo your lectures than TH-cam? If not, are there any plans to have such a platform? Many thanks for your efforts!
For the foreseeable future TH-cam is the best platform both in terms of visibility (2nd most popular search engine on the internet) and also for revenue, I make a lot of money from AdSense. I don't think that will change for a very long time.
I dont think plants have any immune system like animal cells, mostly might be because of the thick cellulose wall which doesnt let most microorganisms attack plant cells. The traditional immune system as we understand generally is composed of WBCs and other immune cells which directly attack pathogens, plants dont have such level of sophistication though and i generally like to call it a defensive system rather than active threat/immune response. Waxy covering, spikes, thorns, hard covers stop big and small predators(fungi, some bacterias etc) from getting inside the cell. If pathogens do get inside, the cell can self destruct itself, the information are encoded in the cells itself and is also controlled by hormones, chemical stimuli from the cell itself. Basically the way i like to understand it is that, in case of mammals(humans specifically) specialized cells will help you win over microorganisms while for plants, the individual cells has instructions in itself which can help the entire plant body survive. Another way to think is (even though plants do send chemical signals via hormones and other methods to warn other cells of incoming attacks) plants immune system/defense system is more localized as opposed to humans which are far more centralized(WBC production in specific sites, antibodies spread all over the body etc)

Thanks Dave, this would have helped me last semester.
I'm just curious; how have your studies been going since then?
@@PunmasterSTP pretty good
@@ethanbumpus9580 Glad to hear it!

I missed a few days so I really needed this.
Emphasis on the pastense
Thanks lovde
woww professor is gaining around 1k every day , as he deserves , and even more , waiting for new modern physics video ...
:D
He is a maestro of biology and other subjects. Thanks sir.

Amazing video. Recently got interested in botany
I really waited for this video 😍🔥
Tnx sir
Waiting for 1M subs🔥🔥

It's 1.35 M already

You made the content soo easy. Thank you 😊
Thanks really helped me for my grade 6 school

I'm loving this so much.

Thanks so much ☺️ it help me a lot
Thanks! excited for this series.
Yes! More botany pls.
thank you very much .
YES! was eagerly waiting for this :)
Thank u sir it can help me understand plants
ස්තූතියි. Love you ❤
Thank you so much :) I love science and plants... You made my day happier
Thanks, that was just so clear. A delight.
This was very helpful
thanks a lot for providing this.GREAT
Helpful to undestand.

Nice explanation professor
BRILLIANT VIDEO .
U are THE BESTT
thanks, prof.Dave
Can u make a video about how fungi benefit plants
AWESOME CHANNEL

Is there a plant immune system as well? In which cells would that be organized?

Shouldn’t you mention the intra-cellular spaces between parenchyma cells. Other plant tissues don’t have them.
Muito bom!
so abaca have so many sclerenchyma cells
Why did you cut your hair man , you looked awesome bro
Yeah
😢😊
Super💓❤🎉😍🥰❤🧡💛💚💙💜💛🤍🤎❣️💕💞💓💗💖💝
Second view sir...
How to improve my iq and I like your videos respect and love from egypt
English pronunciation of scientific terms is incredibly goofy to me
watched this like 10 times, ur great thanks dave 🫶🏻✨
