what is phototsynthesis and how does it work? what is cellular respiratipn an d how does it work?

photosynthesis is the process by which plants obtain energy. it starts with sunlight hitting thw chloroplasts and on eelectron is started being transported down a long chain. as it moves there is a substance called ATP that is produced this is then "burned" for energy. how ever some plants are ingested by animals, the atp that is stored is then used to perform cellular respiration. the process uses 2 molecules of ATP to produce 32 molecules of ATP. this is also done by moving one electron though a long chain of reactions.
