I literally have a biology test tomorrow and I'm just going over nearly everything today because I've been bust revising other tests. Thankyou so much!
im not happy that this video was created, all I wanted to do in quarantine was watch tiktok, but because of this video I now have to study biology. I am truly disappointed and will be crying and yawning for the next 20mins. ha lol you really read all that waffle :)
It’s my second year since I moved to IGCSE and this channel has helped me out so much, I have a bio test tomorrow and now notes to help this has really helped thank you so much
I must say, This channel is severely underrated, my friends and i were about to start a similar one called CAMBEE COGNAITO, but then i saw this, its similar names and content seeming like we copied this one, so we may be deciding to back off.🙂🙂
Tiny gaps on the underside of the leaf which allow CO2 to diffuse in and 02 to diffuse out. The guard cells control when they're open and closed for example the guard cells are light sensitive so the stomata close at night time. Hope that helps. 🙃
