The stomata arc closes at which of the following temperature? (In centigrade)
Correct answer: A. 45°C
- A. 45°C
- B. 35°C
- C. 15°C
- D. 25°C
Explanation
Despite the fact that the stomata open in response to light, they may close on a hot day in order to conserve water. This is because the heat may cause the water to evaporate out through the stomata, causing the plant to lose water, reducing the water potential inside the leaf. Stomata are closed at 45°C.
