Хлорофилл 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, хлорофилл a is important for the growth and development of plants. It helps capture light energy and transfer it to other molecules involved in the energy conversion process. This makes it essential for the survival of many ecosystems on Earth.
