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.
What is the most likely outcome if drops of salt water are added on top of stomata?
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.
Does the stomata close during drought?
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.
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.
Why does having too much stomata increase water loss?
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.
Where does water plants have stomata?
to prevent excessive water loss by transpiration
Where are stomata located on a eucalyptus leaf?
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.

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.
Is the loss of water from plants?
Plants lose most of their water by transpiration through the stomata of the leaves.
What does a CAM plant do?
Slows water loss by opening stomata only at night
