Answer 1

The correct role of chlorophyll in photosynthesis is:

It collects and converts light energy to energy contained in chemical bonds.

Chlorophyll is a pigment found in the chloroplasts of plant cells that absorbs light energy, primarily from the blue and red wavelengths of light. This energy is then used to drive the light-dependent reactions of photosynthesis, where water is split, and energy-rich molecules like ATP and NADPH are produced. These energy molecules are then utilized in the Calvin cycle to convert carbon dioxide into glucose.
