What is the function of chlorophyll in plants?

Chlorophyll plays a crucial role in the process of photosynthesis, which is how plants convert light energy into chemical energy stored in glucose. This green pigment is primarily located in the chloroplasts of plant cells and is responsible for capturing sunlight. When chlorophyll absorbs light, it energizes electrons, initiating the series of reactions that transform carbon dioxide and water into glucose and oxygen.

The ability of chlorophyll to absorb specific wavelengths of light—primarily blue and red—maximizes the efficiency of this energy conversion process. Without chlorophyll, plants would not be able to harness solar energy effectively, making it essential for their growth and energy production. While other options relate to important functions in plants, they do not accurately describe the primary role of chlorophyll.
