Biology

Pigments in the chloroplast, mainly chlorophyll, absorb sunlight (specifically light in the blue and red wavelengths) to power the process of photosynthesis. The absorbed light energy is used to convert carbon dioxide and water into glucose and oxygen during the light-dependent reactions of photosynthesis.

The other option is incorrect:

Option A: While sunlight does bring heat, the primary purpose of pigments like chlorophyll is to absorb light energy, not heat.
