Penjelasan
Chlorophyll and carotenoid are photosynthetic pigments. Carotenoid is a crucial accessory pigment in plants and algae that helps capture light energy from the sun and transfer it to chlorophyll, thereby enhancing the efficiency of photosynthesis by expanding the range of wavelengths absorbed by the plant.
Cytochrome is not considered a photosynthetic pigment; it is a protein involved in the electron transport chain, not directly involved in capturing light energy for photosynthesis.
