When open, the stomata can release water. The more dense or larger the stomata are, the more water they can release.

Which do guard cells control?
excess water loss
Why are cutin stomata and guard cells absent in elodea?
Cutin, stomata and guard cells are used for water loss prevention. These are not needed because Elodea is a water plant.
How does climate affect leaf structure?
the leaves begin to adapt by having waxy layers and hairs to avoid the maximum loss of water i deserts. and also by formation of more specialised stomata
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 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.
How is the lost water in stomata replaced?
The guard cells of the stomata have greater osmotic pressure due to loss of water. Thus, by way of osmosis this loss is compansated continuously from the surrounding cells of the stomata.
Where does water plants have stomata?
to prevent excessive water loss by transpiration
To control water loss the size of the stomata is reduced by the?
Guard Cells
What can open and close to change the amount of water loss?
stomata
How has the succulent adapted its stomata to prevent to much water loss?
Bot
Which do guard cells control?
excess water loss
Guard cells close the to prevent excess water loss?
stomata
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
Why are cutin stomata and guard cells absent in elodea?
Cutin, stomata and guard cells are used for water loss prevention. These are not needed because Elodea is a water plant.
What plant leaf is adapted to prevent water loss?
Most of their stomata are on the underside of the leaf.
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
