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?
By opening and closing the stomata on the underside of the leaves.
How does stomata control water loss from plants?
By closing the stomata of the plant during times when water is in short supply, there will be decreased transpiration. Transpiration is the movement of water through the plant as well as it's evaporation rate.
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?
Stomata are a plants way of exchanging gasses in photosynthesis. The stomata also are resoponsible for transpiration. Most plants have stomata on the under side of the leaf in order to prevent too much water loss. There already is a lot of stomata in leaves but I think you mean to ask "What would happen if the stomata were open all the time?" this would result in mass water loss and cause a plant to wilt.Edited answer:Large number of stomata will increase porocity of the leaves and will facilitate better gaseous exchange and more transpiration.
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?
wind at greater speeds cause the plant to close their stomata(pores underneath the leaves) to close to prevent water loss reducing transpiration. medium speeds cause plant to transpire more, because it removes more water molecules around the stomata while they stay open and it brings more CO2 to the plant. no wind speeds allow the stomata to remain open and water molecules to stay around the stomata reducing the amount of water loss, causing only some transpiration.
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.
