Photosynthesis is an endothermic reaction- energy is added (endo-in, exo-exit)
H2O + CO2 ==> C6H12O6 + O2Photosynthesis is a process by which plants uptake water and carbon dioxide from their surroundings and use energy from the sun to convert these into oxygen and glucose. The water produced by the plant then leaves via the stomata found at the bottom layer of leaves and glucose can be used to from longer sugar chains such as starch for storage or it can be used as building blocks to form cellulose fro structure.
