Chlorophyll_b is a green pigment found in plants, algae, and some bacteria. It plays a crucial role in photosynthesis by absorbing light energy, primarily in the blue and red wavelengths. This energy is then used to convert carbon dioxide and water into glucose and oxygen, providing energy for the plant's growth and development. Unlike Chlorophyll_a, which is the main pigment in photosynthesis, Chlorophyll_b assists by capturing additional light energy and transferring it to Chlorophyll_a. This allows plants to utilize a broader spectrum of sunlight, enhancing their ability to produce food and thrive in various environments.
