The primary role of chlorophyll in photosynthesis is to:

Chlorophyll plays a crucial role in photosynthesis as the primary pigment responsible for capturing sunlight. It absorbs specific wavelengths of light, predominantly in the blue and red parts of the electromagnetic spectrum, while reflecting green light, which is why plants appear green. This absorption of sunlight provides the energy necessary to drive the chemical reactions involved in photosynthesis, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Understanding that chlorophyll does not store energy, reflect sunlight significantly, or convert sunlight directly into glucose clarifies its specific function in the photosynthetic process. Rather, chlorophyll's primary purpose is to absorb sunlight, which is then utilized in the conversion of energy through various biochemical pathways, eventually leading to glucose production.
