Question about plants and wavelengths in photosynthesis?

Question

Plants use both blue and red wavelengths of light (parts of visible light) for photosynthesis. If there was a change in the wavelengths of light that reached the planet surface that resulted in the elimination of the red wavelengths of light, what would happen to the rate of photosynthesis and the rate of oxygen production?

a) the rate of photosynthesis would go up, the rate of oxygen production would go up

b) the rate of photosynthesis would go down, the rate of oxygen production would go up

c) the rate of photosynthesis would not change, the rate of oxygen production would not change

d) the rate of photosynthesis would go down, the rate of oxygen production would go down

e) none of the above

Anyone 100% confident of this answer? I'd appreciate your help. Thanks!

Answer 1

Its D for sure.

Photosynthesis depends on the energy absorbed from light. Therefore red light is removed, the rate of photosynthesis is affected negatively.

On the other hand, Oxygen is produced directly by photosynthesis. Therefore by reducing photosynthesis oxygen production is also reduced.
