The reaction of photosynthesis occur in the ... of plant cells

Photosynthesis is a reaction that occurs in a plants leaves or their chloroplasts it helps provide food for the plant and oxygen which is necessary for the survival of species

Explanation: I hope this helps!

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
