@@mainishizawa5367 we understand how it may seem that way from the phrasing but they are in the correct order! Adhesion occurs between molecules of different substances, whereas cohesion occurs between molecules of the same substance. We hope this helps!
i think though the definitions are correct, the arrws pointing at the interactions between molecules were accidentally switched. but the descriptions are correct nonetheless :)
On the phloem adaptations part. Instead of the sieve tube cells having a Lot of mitochondrias and folded membrane, Don’t do companion cells actually have this characteristics? In my IB book it says that the companion cells are the ones with mitochondria because of active transport happening in these cells
Great question! Phloem parenchyma cells and companion cells (which are also a type of parenchyma cells) both carry out metabolic functions and active transport for the phloem and thus contain many mitochondria. Because of the nuanced difference, we merged the parenchyma with the phloem to simplify it. However, you can safely run with companion cells containing more mitochondria as you have suggested. Hope that helps!
You have no idea how much of clutch this is when my bio mocks are coming up, thanks Teach Tiber
Wishing you the best of luck!
you have no idea how much this is saving me, thank you so much
You are so welcome!
Got bio paper 2 in 3 hours lol im boutta clutch up
Do you have the adhesion and cohesion switched? 7:18
