Emerson effect is associated with

Options

(a) respiration
(b) transpiration
(c) salt absorption
(d) photosynthesis

Correct Answer:

photosynthesis

Explanation:

Emerson (1943) discovered the existence of two photosystems (PSI and PSII). Emerson conducted experiments where he showed that in two wavelengths of light (i.e., one shorter and the other longer) there is a very high rate of photosynthesis. The enhancement of photosynthetic rate under influence of two wavelengths of light is called Emerson effect.
