Question

Emerson effect is related to

• A. Photosynthesis
• B. Respiration
• C. Transpiration
• D. Absorption of water

Answer 1

The correct option is A Photosynthesis

The Emerson effect is the increase in the rate of photosynthesis after chloroplasts are exposed to the light of wavelength 680 nm (deep red spectrum) and more than 680 nm (far red spectrum). The effect was early evidence that two photosystems, processing different wavelengths, cooperate in photosynthesis.

So, the correct option is 'Photosynthesis'.
