hehe hold on there ^^

-What are the functions of water.
* our cells are mostly water , used to transport stuff around the body.. keeps cells turgid in plants.. cant think of more

-important of osmosis.
*cells draw water in by osmoses to keep there cells turgid and healthy

-why does active transport occurs even though we hv diffusion?
* active transport is against the concentration gradient from low concentation to high concentration.
example: when a plant takes in nitrate ions from the soil .. they take them from the soil althu the concentration in the soil is lower than the plant. Active transport needs energy so more respiration needed

i would strongly advise you to revise 'how does wilting occur'
nitrogen cycle
protien synthesis
antagonistic muscles and asexual/sexual reproduction.
seend dispersal- wind/insect
everything possible about the placent and homeostasis


this is all i remember.
hope it is helpful
