Differences between photosynthesis and cellular respiration

1) Photosynthesis is where glucose is produced while respiration is where glucose is broken down
2) Photosynthesis is endothermic while respiration is exothermic
3) Respiration may need oxygen to occur while Photosynthesis produces oxygen as a by-product
4) Photosynthesis only occurs in organisms that produce chlorophyll (plants and cyanobacteria) while respiration occurs in most cells.
