Low transpiration during a storm is due to
Low transpiration during a storm is due to
The correct option is: C
Explanation of the correct option:
Transpiration is the process of water passing out from the surface of a plant or leaf.
Air movement or wind increases the rate of transpiration by bringing dry air and removing moist air around the transpiring material. Air movement or wind increases the rate of transpiration by bringing dry air and removing moist air around the transpiring material. High wind velocity, however, closes stomata, thus, reducing transpiration.
Factors Affecting Transpiration in Plants
Relative Humidity: The rate of transpiration is inversely proportional to relative humidity. More the relative humidity less is the transpirate rate.
Temperature: A high temperature lowers the relative humidity and opens the stomata even in darkness. As a result, the rate of transpiration increases.
Light: The stomata open during the day and close in the dark. The presence of light is directly proportional to the rate of transpiration.
Air: If the air is moving, the saturated air around the leaves is removed and the transpiration rate increases.
Water Availability: The transpiration rate is directly proportional to the absorption of water by the roots from the soil. A decrease in water absorption causes the closure of stomata and wilting, thereby reducing the rate of transpiration.
Surface Area of the Leaves: A leaf having more surface area will show more transpiration rate than a leaf with a lesser surface area.
Explanation of the incorrect option:
Option A: The rate of transpiration is inversely proportional to relative humidity. More the relative humidity less is the transpirate rate
Option D: A high temperature lowers the relative humidity and opens the stomata even in darkness. As a result, the rate of transpiration increases.
Final answer: Low transpiration during a storm is due to the high velocity of winds.z
