What is the sun's role in photosynthesis?

Photosynthesis is a process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy that is stored in glucose or other organic compounds. The sun's role in photosynthesis is to provide the energy needed for the process.

Chloroplasts in plant cells contain pigments called chlorophyll that are responsible for absorbing light energy from the sun. This energy is then used to convert carbon dioxide and water into glucose and oxygen. The oxygen is released into the atmosphere, while the glucose is used as a source of energy and building material for the plant.

Without the sun's energy, photosynthesis cannot occur, and life as we know it would not be possible on Earth.
