Chlorophyll B is a type of green pigment found in plants, algae, and some bacteria. It plays a crucial role in photosynthesis, the process by which these organisms convert sunlight into energy. Chlorophyll B absorbs light primarily in the blue and red-orange wavelengths, helping to capture energy that is then used to produce food. Unlike Chlorophyll A, which is the main pigment in photosynthesis, Chlorophyll B assists by expanding the range of light that plants can use. This pigment is especially important in capturing light in shaded areas, allowing plants to thrive in various environments.
