    Do you have the adhesion and cohesion switched? 7:18

      @@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

    • @tibertutor

      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!
