Which is least important in photosynthesis?
Correct answer: D. Green light
- A. Red light
- B. Blue light
- C. Sunlight
- D. Green light
Explanation
Greenlight range spectrum is considered as least effective for the process of photosynthesis: The wavelength of green light is thought to be the least efficient for photosynthesis. If the plants are exposed to green wavelengths during photosynthesis, the rate of photosynthesis will be the slowest. This is due to the presence of chlorophyll, a green pigment. Instead of being absorbed by the chlorophyll, the green light is transmitted and reflected. The best visible light wavelengths for photosynthesis are blue (425-450 nm) and red (600-700 nm).
