Chlorophyll a

Chlorophyll a is a green pigment found in plants, algae, and cyanobacteria, crucial for photosynthesis—the process by which these organisms convert sunlight into energy. It absorbs mainly blue and red light, reflecting green, which is why plants appear green. Chlorophyll a plays a vital role in transforming carbon dioxide and water into glucose and oxygen using sunlight. This process not only fuels the plant’s growth but also produces oxygen, essential for life on Earth. Essentially, chlorophyll a is key to both plant health and the overall ecosystem.
