What is the primary function of chlorophyll in plants?

The primary function of chlorophyll in plants is to facilitate photosynthesis. This pigment is essential for capturing light energy from the sun, which is then used to convert carbon dioxide and water into glucose and oxygen. The process of photosynthesis primarily occurs in the chloroplasts of plant cells, where chlorophyll primarily resides. By absorbing light most efficiently in the blue and red wavelengths, chlorophyll helps maximize the energy plant cells can harness from sunlight, driving the chemical reactions necessary for producing food and energy. This is critical not only for the plant's survival and growth but also plays a vital role in the overall ecosystem by providing energy for herbivores and, indirectly, for larger animals.
