Хлорофіл a is a green pigment found in plants, algae, and cyanobacteria. It plays a crucial role in photosynthesis, the process by which these organisms convert sunlight into energy. This pigment absorbs light primarily in the blue and red wavelengths, reflecting green light, which is why plants appear green. In addition to its role in photosynthesis, хлорофіл a is important for the growth and development of plants. It helps in the formation of energy-rich compounds, which are essential for various biological processes. This pigment is also used in research and has potential applications in medicine and nutrition.
