How does pH affect the rate of transpiration of a plant and why?
Stomata open in the presence of bases and close in the presence of acids. Therefore, the rate of transpiration is higher in bases due to that they are losing more water through their open stomata.
What happens to stomata in saline solution?
The stomata are closed when exposed to saline solution or salt water. If a plant is exposed to the salty water it will become dehydrated and eventually die. Uness the plant is a type of mangrove or is salinity tolerant plant.
What is the role of a stomata and guard cells?
Through the stomata carbon dioxide diffuses into the plant and oxygen and water vapor diffuse out of the plant. Guard cells control the opening and closing of the stomata. Used in arid climates to control water loss for instance.
Shortage of water causes the stomata to?
Shortage of water causes the stomata to close.
Does the stomata close during drought?
The stomata will mostly close during drought. The stomata are responsible for the storage of water in plants. The opening and closing of the stomata regulates the amount of water in plants.

Which type of plant cells open and close the stomata to adjust the flow of air and water into and out of the plant?
Gaurd cells
What is the plant responsible for limiting water loss?
Guard cells, which open and close stomata. Also, cutin.

What happens when the stomata on a plant's leaves are open?
Stomata, which are holes in the epidermis of plants, allow for gas exchange and the passage or retention of water for the plant. Stomata enable respiration (gas exchange) in plants that provides for photosynthesis. Photosynthesis produces food for the plant from the transformation of oxygen from carbon dioxide, via the stomata as the pathway into the plant. Stomata also allows the passage of water into the plant (Transpiration), since the leaves are mostly covered by wax (the cuticle). Water can enter the vascular system, transporting nutrients and such to the rest of the plant. The stomata can also retain water in case of a shortage of water, like a drought, and prevent water loss, enabling the plant to survive longer.-Katydid2014Stomata are tiny holes on the bottom of a leaf. They open and close depending on the situations surrounding the plant. When the stomata are open, water is lost from the plant through evapotranspiration, which is when they evaporate from the surface of the leaf. The stomata close at a certain period of time in order to keep this water in. The stomata also open in order to let more carbon dioxide in, which is needed for photosynthesis. For example, if there is an increase in light around the plant, the stomata will open more often for photosynthesis, and will lose more water from the plant.
Shortage of water causes the stomata to?
Shortage of water causes the stomata to close.
Does the stomata close during drought?
The stomata will mostly close during drought. The stomata are responsible for the storage of water in plants. The opening and closing of the stomata regulates the amount of water in plants.
When the stomata in a leaf close during the day then?
Stomata close during the night because the water will evaporate ( they do this to conserve water).
What job does a stomato cell do?
Stomate? The only thing that comes to mind is the word STOMATA. IF that's what your talking about, a stomate must be ONE ...stomate....whereas stomata are a pair of stomates.. Assuming the above...Stomata are found on the undersurface(?) or maybe the top surface of leaves. For a visual, think of two parentheses...( ). If there is a DRY period the stomata CLOSE () to prevent the plant from losing water and open when the plant has to release water. Basically, the opening and closing to the TWO stomates, acting together, (stomata) regulates transpiration through the leaves of a plant. Hope that's what you were talking about. Open ( ) Closed
What are the openings in the epidermis of a plant that allow air and water to pass in and out of the leaf?
Yes, the stomata, which are pores in the lower epidermis of the leaf and are surrounded by 2 guard cells, open in the day to let in CO2 for photosynthesis but they also release H2O as water vapour and they close at night to reduce water loss.
Why does stomata close under strong sunlight?
The stomata close during strong sunlight so they don't lose excess water. The stomata is how water is excreted from the cell.
