Carotenoids are a class of pigments found in plants, algae, and photosynthetic bacteria that play a crucial role in light absorption during photosynthesis. These pigments are responsible for the vibrant yellow, orange, and red colors in many fruits and vegetables, as well as in plant tissues. In addition to their role in photosynthesis, carotenoids also help protect plants from light stress by dissipating excess energy and acting as antioxidants.
