How Do Photosynthesis and Respiration Differ in Plants and Animals?

[RainGurl]

I have been asked to compare photosynthesis and respiration (occurrence in plants and occurrence in animals). I am not sure how to go about answering this question.

Can someone explain it to me?

If it was me answering the question I would refer to the flow of electrons; compare reduction and oxidation at each of the various stages. I would also comment on the relationship between photosynthesis and respiration in plants.
