What does photosynthensis mean?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using sunlight to transform carbon dioxide and water into glucose and oxygen. This process primarily occurs in the chloroplasts of plant cells, where chlorophyll captures light energy. Photosynthesis is essential for life on Earth as it forms the base of the food chain and produces the oxygen necessary for many living organisms.
