Assertion Light is very important factor in transpiration. Reason It induces stomatal opening and darkness closing. Therefore, transpiration increases in light and decreases in dark.

Assertion Light is very important factor in transpiration. Reason It induces stomatal opening and darkness closing. Therefore, transpiration increases in light and decreases in dark. (A) If both Assertion and Reason are true and reason is correct explanation of Assertion (B) If both Assertion and Reason are true but reason is not the correct explanation of Assertion (C) If Assertion is true but Reason is false (D) If both Assertion and Reason are false

Light induces opening of stomata and increase the temperature, both these factor help in increase of transpiration while darkness causes closure of stomata and reduces the rate of transpiration. Transpiration depends on closure and opening of stomata.
