None of the options listed directly define photosynthesis. However, photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose (a type of sugar) using carbon dioxide and water. It primarily occurs in the chloroplasts of plant cells and involves the pigment chlorophyll.
If you are looking for a specific choice, it seems there is an error, as the correct option is not among those provided. Would you like more information about photosynthesis?
