Does anybody know the comparison and contrast of the processes of cellular respiration and photosynthesis? I can't quite seem to grasp this one. Help!

Well, for a start, why don't you write down the net reactions for each?

Google it...i guarantee that you'll find what you want

Well, the products of phtosynthesis is oxygen and glucose; the products of cellular respiration is energy. One is a process of making chemical that can store energy, another one is breaking down the storage chemical. I think this can be one of the differences. Isn't it?

Also, msot of the living things on the earch carry out respiration while only green plants carry out phtosynthesis. One of them releasing caron dioxide while another absorb.

Quite lots of differences...
