When open, the stomata can release water. The more dense or larger the stomata are, the more water they can release.
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.
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.
The most likely outcome of adding drops of salt water on top of stomata is that the salt water will disrupt the normal function of the stomata, potentially leading to the stomata closing and affecting the plant's ability to exchange gases and regulate water loss.
Yes, during a drought, plants close their stomata to conserve water and prevent excessive water loss through transpiration. This helps the plant maintain its hydration levels and survive the dry conditions.
Stomata close under strong sunlight to prevent excessive water loss through transpiration and to protect the plant from drying out. Closing the stomata reduces the amount of water vapor that can escape from the leaf surface, helping the plant conserve water.
to prevent excessive water loss by transpiration
Stomata are like pores that are meant to control water levels, especially in transpiration. The right number of stomata keeps the plant in equilibrium, too many and the plant loses too much water, drying out and dying.
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.
Eucalypts are called "sclerophyllous" which means 'hard leaves'. This means they are hardy in low water conditions. They hang vertically so they are not exposed to the midday sun which reduces water loss through transpiration. For this reason many have stomata and chloroplasts on both sides of the leaf.
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.

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.
Plants lose most of their water by transpiration through the stomata of the leaves.
