Question

A reduction in the quantity of oxygen evolution during photosynthesis may be observed at (A) Light having wavelength more than 680 nm (B) Light having wavelength less than 680 nm (C) Light having wavelength 560 nm (D) Light having wavelength less than 360 nm

Tardigrade Admin · Accepted Answer

Plants use radiations of wavelength between 400 - 700 nm for photosynthesis. It is called as photosynthetically active radiation (PAR). Therefore, below 400 nm photosynthesis does not take place and oxygen will also not release as the oxygen releases by the photolysis of water during photosynthesis
