Final answer:
Light color affects photosynthesis by influencing the absorption of light by the plant's pigments. Different pigments in plants absorb specific wavelengths (colors) of light.
Step-by-step explanation:
Light color affects photosynthesis by influencing the absorption of light by the plant's pigments. Different pigments in plants absorb specific wavelengths (colors) of light. Chlorophyll, the main pigment involved in photosynthesis, absorbs blue and red light most efficiently. Thus, plants grown under blue or red light would likely have higher rates of photosynthesis compared to plants grown under green or orange light. Therefore, the predicted order of growth from most to least for plants A, B, and C would be: Plant A (blue light) > Plant C (orange light) > Plant B (green light).
