The role of carotenoid pigments in plants is to absorb light energy for photosynthesis and provide color to flowers and fruits, aiding in pollination and seed dispersal. These pigments primarily absorb wavelengths in the blue and green parts of the light spectrum, reflecting yellow, orange, and red hues. Besides their role in photosynthesis, carotenoids also serve as antioxidants, protecting plant tissues from damage caused by excess light and environmental stress. They are essential for plant health and contribute to the nutritional value of many fruits and vegetables.
