Question

why is photosynthesis endothermic?

Answer 1

because in photosynthesis heat is taken by leaves in the presence of chlorophyll so it is endothermic where respiration is exothermic bz heat is produced

Answer 2

An endothermic process is one that needs to have energy added in order to take place. A simple example of an endothermic process is the melting of ice, because ice doesn't melt unless you put energy into it.In the case of photosynthesis, nothing much happens until light hits the chlorophyll in the leaves, causing electrons to move around and a whole bunch of other complicated stuff to take place. The specific stuff isn't the important part - what is important is that without the addition of energy in the form of light, nothing will happen . if help full plzzz marks as brilliant answer.
