Please translate the following English into Chinese. Photosynthesis occurs only in the chlorophyll -containing cells of green plants, algae , and certain protists and bacteria. Overall, it is a process that converts light energy into chemical energy that is stored in the molecular bonds. From the point of view of chemistry and energetics, it is the opposite of cellular respiration. Whereas cellular respiration is highly exergonic and releases energy, photosynthesis requires energy and is highly endergonic.
