Control Assessment help? Osmosis

Go over your book, be ready for any detailed definitions, describe and explain any effects and make sure you can apply osmosis to a variety of situations (i remember we had to apply it to blood cells, but plant cells might also come up) also useful to make sure you can describe and explain the effects on osmisis (ie temperature on membrane permeability, and water potentials are the most obvious)

hope that helps, have fun

ive just realised your GCSE so some of what ive said might not apply to you until you get to a level, but I guess its better to be over prepared! Good Luck
