I just find all the modules horribly boring then because of that I find them harder to "take in" when revising. Well done on your mock!

this might seem like a really stupid question, but in diffusion and osmosis can you only go from a high concentration to a low concentration? (like you couldn't do it in reverse?)

yeah you can't do it in reverse...
i swear the reverse is called active transport anyways? But obviously active transport is when it carries these molecules using energy from respiration

Hi I may be wrong but doesn't osmosis go from low to high concentration because the water goes through the membrane into the solution making it more concentrated as it only works one way? Eg roots taking in water

I swear osmosis is when water molecules go from high to low concentration? Because theres more water in the soil than in the roots of the plant, i'm assuming...
