What is the role of sunlight in photosynthesis?

Sunlight provides the energy required to carry out photosynthesis. It is the primary source of energy that drives the entire process.

Chlorophyll in the leaves absorbs sunlight and converts this light energy into chemical energy. This energy is then used to convert carbon dioxide and water into glucose during photosynthesis.

Without sunlight, the process cannot occur because there would be no energy available to power the chemical reactions involved.

Thus, sunlight is essential for food production in plants and for maintaining life on Earth.
