Transport System in Plants & Animals
Solution
Which of the following statements about the rate of transpiration is INCORRECT? It is
A
Dependent on temperature
B
Affected by changes in light intensity
C
Unaffected by humidity
D
Dependent on air movement
E
Affected by availability of water
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
Unaffected by humidity: This statement is false because the rate of transpiration is heavily affected by humidity. Transpiration depends on a water vapour concentration gradient between the inside of the leaf and the surrounding air. When humidity is high, the air is already saturated with moisture, which decreases this gradient and slows down the rate of transpiration. When humidity is low (dry air), the gradient is steep, and transpiration speeds up.
