    That's what I did as well. Let's hope it's right.

    Animal cells - shrink (hypertonic => high solution concentration in the solution, therefore less water, hence water moves via osmosis ([high H2O] -> [low H2O]) out of the cell into the solution)
    Plant cells - plasmolysed.

    You're right.

    It only asked about plant though, didn't it? Oops if it asked for animal too

    For the visking tubing one: I said it'd increase? Because it was a solution(it had amino acids in it and something else I can't remember) inside the bag, and water outside the water would move in as the solution was hypertonic? And something about how starch wouldn't diffuse or something because it's too big a molecule? idk.

    I wish it wasn't a write on paper so I could look over it...

    I put false- photolysis,
    true,
    false- but I put ADP+Pi, because ATP is what is released, not what is used as an energy source? I'm not sure.
