The primary component of photosynthetic pigments is chlorophyll, which is responsible for capturing light energy from the sun during photosynthesis. Chlorophyll primarily absorbs light in the blue and red wavelengths while reflecting green light, which gives plants their characteristic color. This pigment is crucial for converting solar energy into chemical energy, providing the foundation for energy flow in ecosystems. Other pigments, such as carotenoids, also play a role in capturing light energy and protecting against oxidative damage.
