What is the function of chlorophyll in plants?

Chlorophyll plays a vital role in the process of photosynthesis by capturing light energy from the sun. This green pigment, primarily found in the chloroplasts of plant cells, absorbs light most efficiently in the blue and red wavelengths while reflecting green light, which is why plants appear green. The energy captured by chlorophyll is then used to convert carbon dioxide and water into glucose and oxygen, providing essential energy for the plant and serving as the foundation of the food chain for other organisms. This function is critical, as it allows plants to produce their own energy, facilitating growth and contributing to oxygen production in the atmosphere.
