The main pigment found in green plants is chlorophyll. This pigment is crucial for photosynthesis, the process by which plants convert sunlight into energy. Chlorophyll absorbs light, primarily in the blue and red wavelengths, and reflects green light, which gives plants their characteristic color. There are two main types of chlorophyll: chlorophyll a and chlorophyll b, both of which play essential roles in capturing light energy. By facilitating photosynthesis, chlorophyll is fundamental to the survival of plants and, consequently, to the entire ecosystem, as it contributes to oxygen production and serves as the base of the food chain.
