Which of the following functions reduces the water loss through the epidermis of aerial parts of the plant?Closing of stomataOpening of stomataClosing of lenticelsOpening of lenticels
Solution
The function that reduces the water loss through the epidermis of aerial parts of the plant is the closing of stomata.
Here's a step-by-step explanation:
-
Stomata are tiny openings or pores in plant tissue that allow for gas exchange. They are typically found in the epidermis of leaves but can also be found on other parts of a plant like the stem.
-
When the stomata are open, water vapor can escape from the plant in a process called transpiration. This is beneficial for the plant as it helps to cool it down and allows for the movement of minerals and water from the roots to the rest of the plant.
-
However, in conditions where water is scarce, it's important for the plant to conserve as much water as possible.
-
Therefore, the stomata will close to prevent water loss. This is typically controlled by the plant's internal water balance and external factors like light, carbon dioxide concentration, and temperature.
-
Lenticels, on the other hand, are small raised areas in the bark of stems and roots that enable gas exchange between the plant and the atmosphere. They do not play a significant role in water loss.
So, the function that reduces water loss through the epidermis of aerial parts of the plant is the closing of stomata.
