They open in order to allow to allow air containing carbon dioxide to enter the leaf
Edited answer:
Distilled water is readily taken by the cell sap of gaurd cells of stomata by endo-osmosis and when gaurd cells become turgid, the stomatal pore becomes prominent

How does the stomata density affect the water loss?
When open, the stomata can release water. The more dense or larger the stomata are, the more water they can release.
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.
Why don't plants keep their stomata open all the time?
Plants don't keep their Stomata open all the time to prevent too much water loss.
When are the stomata of leaves usually open?
Depending on the environment of the plant, stomata will open and close at different times. In hot, dry environments stomata will open around dusk and dawn to minimise water loss. In Wet environments stomata will open during the day as needed
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.

Water vapor moves out of leaves through open stomata This process is known as?

What can open and close to change the amount of water loss?
stomata

When a plant has enough water the what swells and pull open the stomata so the plant can breathe?
water
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.
How does stomata open?
The stomata's function is to allow gas exchange with the surrounding air, so that the plant can intake carbon dioxide and oxygen. Stomatal opening is favored when there is plentiful water and moderate temperatures. Abscissic acid, a plant hormone, acts on the guard cells to open and close stomata. Some plants are even genetically engineered with a mutated era gene, which makes them more sensitive to abscissic acid and more prone to the opening and closing of guard cells. When guard cells are full of water, they stretch away from each other and the stomata are open. When guard cells are limp, they fall on each other and the stomata are closed. Potassium ions play a role in the opening and closing of stomata by changing the concentration of ions in the guard cells. When the potassium ions are in the guard cells, water also flows in the guard cells because of osmosis and the stomata open. When the potassium ions are out of the guard cells, water also flows out of the guard cells because of osmosis and the stomata close.
The rate of flow of water through the xylem is regulated by?
the stomata in the leaves. When the stomata open, water is able to evaporate from the leaves, creating a pressure gradient that allows water to be pulled up through the xylem. When the stomata close, this flow of water is reduced or stopped.
