Stages of photosynthesis Stage one: light reactions. Is it really as simple as that? Breaking down photosynthesis stages. During photosynthesis, autotrophs use the sun’s energy to make carbohydrate molecules from water and carbon dioxide, releasing oxygen as a byproduct. Almost all the oxygen present in the atmosphere can be attributed to this process, which also means that respiration and photosynthesis go together. Carbon dioxide and oxygen enter/exit the leaves through pores called stomata. Step 1: The plant gathers sunlight from the chlorophyll in the cells to convert into energy.
