Chlorophyll is a green pigment found in the cells of plants and some bacteria. It is essential for photosynthesis, the process by which plants convert sunlight into chemical energy for their growth and development.
Chlorophyll absorbs sunlight, especially in the blue and red regions of the spectrum, and uses that energy to synthesize glucose molecules from carbon dioxide and water.
In addition to its role in photosynthesis, chlorophyll also provides the characteristic green color of plants.
