Why is sun light important to photosynthesis?

Answer 1

Photosynthesis is an endothermic process: it requires energy in order for the reactions involved to occur. The sunlight provides this energy. This is a really simplistic answer; if you want more details, consult any good biochemistry text.

Answer 2

Sunlight is important for photosynthesis because it provides the energy needed to convert carbon dioxide and water into glucose (sugar) and oxygen. This process, carried out by chlorophyll in plant cells, is essential for plants to produce food and release oxygen into the atmosphere.

Answer 3

Photons (light energy) provide the energy to split the H20 molecule, providing the electrons needed for the light reactions of photosynthesis.

Answer 4

photosynthesis is when plants make food.

Sunlight provides the energy for the photosynthesis. It is an essential factor. This energy is stored in glucose
