Question

Write the role of temperature and air flow in transpiration?​

Answer 1

$\huge\blue{Answer}$

Temperature: Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air masses. ... Wind and air movement: Increased movement of the air around a plant will result in a higher transpiration rate.

Answer 2

Explanation:

Transpiration is the removal of water vapour from the plant through the stomata.

Factors affecting transpiration are :

1. Temperature : Increase in temperature causes an increase in the evaporation of water vapour and hence Transpiration increases.

2. Light : Adequate light conditions causes the opening of eand hence Transpiration increases.

3. Humidity: high humidity reduces the rate of transpiration as the nearby atmosphere is somewhat saturated by water vapour.

4. Number of stomata: Higher number of stomata cause increase in Transpiration.

5. Distribution of stomata : Stomata on the upper epidermis of the leaf are more involved in Transpiration whereas stomata on the lower epidermis are less involved in Transpiration.
