The incorrect statement is:
C. Unaffected by humidity
Explanation:
Transpiration is the process by which water is lost from a plant through its stomata. The rate of transpiration is influenced by several factors:
Temperature (A): Higher temperatures increase the kinetic energy of water molecules, leading to faster evaporation and higher transpiration rates.
Light Intensity (B): Increased light intensity stimulates the opening of stomata, allowing more water vapor to escape.
Humidity (C) [Incorrect Statement]: High humidity reduces the rate of transpiration because the air around the leaves is already saturated with water vapor, lowering the water vapor concentration gradient. Conversely, low humidity increases transpiration.
Air Movement (D): Wind removes the water vapor around the leaf, maintaining a high water vapor gradient, which increases transpiration.
Water Availability (E): If a plant lacks sufficient water, it closes its stomata to conserve water, reducing transpiration.
Thus, humidity does affect transpiration, making C the incorrect statement.
There is a spelling error
The selected answer is wrong bcos humidity affects rate of transpiration in which high relative humidity lowers the rate of transpiration and low relative humidity increases rate of transpiration while light intensity has no effects on transpiration
