Sagot :

Final answer:

Stomata in plants regulate transpiration by controlling the loss of water vapor, balancing photosynthesis efficiency with water loss.


Explanation:

In plants, stomata play a crucial role in transpiration by regulating the movement of gases such as water vapor and carbon dioxide. When stomata are open, water vapor is lost to the external environment, thereby increasing the rate of transpiration. This process allows for efficient photosynthesis while managing water loss.
