Question

The level of CO₂ above normal increases the rate of transpiration.

• A. True
• B. False

Answer 1

The correct option is B False

Stomata:

1. Stomata are tiny pores that are present on the surface of the leaves.
2. They allow the exchange of gases between plants and the atmosphere.
3. They allow carbon dioxide to enter and oxygen to exit.
4. There are three environmental factors that affect the opening and closing of a plant's stomata.
5. These are light, water, and carbon dioxide.
6. A sudden increase in carbon dioxide concentration around a leaf will cause the closure of stomata so that excess carbon dioxide does not enter the cell.
7. This will decrease the rate of transpiration.

Final answer: The given statement is false.
