Q.
Which light range is least effective in photosynthesis?
Photosynthesis in Higher Plants
Solution:
Blue and red regions of the light spectrum are most effective in photosynthesis. Blue wavelengths of light carry more energy while red wavelengths have lesser energy. Therefore, the most efficient wavelengths of light efffective in photosynthesis are those of red light. Green light is least effective in photosynthesis.
