Having too many stomata increases water loss because the stomata are the primary sites for water vapor to exit the plant during transpiration. When there are more stomata, the rate of transpiration increases, leading to higher water loss from the leaves. This can be detrimental to the plant if it cannot absorb enough water to compensate for the excess loss.

Why the stomata on undersurface of leaf?
Stomata are mainly found on the undersurface of leaves to reduce water loss through transpiration. The lower surface is generally more shaded and cooler compared to the upper surface, which helps to minimize water loss by reducing the rate of transpiration. Additionally, having stomata on the undersurface can also protect the stomata from direct sunlight, preventing excess water loss.
Do plants lose water through their stomata only when the temperature is hot?
No, plants lose water through their stomata in any condition when they are open for gas exchange. While high temperatures may increase water loss due to higher rates of transpiration, plants can also lose water through stomata during normal conditions for photosynthesis and gas exchange.
Why is the stomata at the top for xerophytes?
Stomata are located on the top surface of xerophyte leaves to minimize water loss by reducing exposure to direct sunlight and wind. Placing stomata on the top surface helps create a more humid microenvironment around the stomata, reducing water loss through transpiration. This adaptation is crucial for xerophytes living in dry environments with limited water availability.
Where does gas exchange and water loss occur in plants?
Gas exchange occurs in the stomata, which are tiny openings on the leaves of plants. Water loss, also known as transpiration, occurs through the same stomata during the process of exchanging gases.
How does stomata control water loss from plants?
Stomata control water loss from plants by regulating the exchange of gases (such as carbon dioxide and oxygen) during photosynthesis. When stomata are open, water vapor escapes through transpiration, but when they are closed, transpiration is reduced to conserve water. Factors such as light intensity, humidity, and plant water status influence the opening and closing of stomata.
Why the stomata on undersurface of leaf?
Stomata are mainly found on the undersurface of leaves to reduce water loss through transpiration. The lower surface is generally more shaded and cooler compared to the upper surface, which helps to minimize water loss by reducing the rate of transpiration. Additionally, having stomata on the undersurface can also protect the stomata from direct sunlight, preventing excess water loss.
How does the stomata density affect the water loss?
Stomata density directly affects the rate of transpiration (water loss) in plants. Higher stomata density means more openings for water vapor to escape, leading to increased water loss. Conversely, lower stomata density reduces the rate of transpiration and helps plants conserve water.
What will happen if there are too many stomata on the top of the leaf?
If there are too many stomata on the top of the leaf, it can lead to excessive water loss through transpiration and make the leaf more prone to dehydration. This can affect the overall health of the plant and its ability to photosynthesize efficiently.
Where does water plants have stomata?
to prevent excessive water loss by transpiration
What is a disadvantage of the change in size of stomata in the presence of light?
The rate of water loss will increase so it will be a disadvantage of the change in size of stomata in the presence of light.
What controls water loss in a leaf?
Water loss in a leaf is controlled by the stomata, which are tiny openings on the leaf surface. When the stomata are open, water vapor can escape through transpiration. The guard cells surrounding the stomata regulate the opening and closing of the stomata to help prevent excessive water loss.
Which do guard cells control?
Guard cells control the opening and closing of stomata, tiny pores on the surface of leaves that regulate gas exchange (such as oxygen and carbon dioxide) and water loss in plants. When the guard cells take in water, they swell and the stomata open; when they lose water, they shrink and the stomata close.
Do windy days decrease a plant's evaporative water loss?
Yes, on windy days, plants experience an increased rate of transpiration due to faster air movement around the leaves, which in turn can lead to higher evaporative water loss. The movement of air removes the water-saturated boundary layer around the leaves, promoting more water loss from the plant.
Do plants lose water through their stomata only when the temperature is hot?
No, plants lose water through their stomata in any condition when they are open for gas exchange. While high temperatures may increase water loss due to higher rates of transpiration, plants can also lose water through stomata during normal conditions for photosynthesis and gas exchange.
