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.
How are the stomata controlled?
The stomata are controlled by two epidermal cells called guard cells. When water flows in, the guard cells swell up and closes the stomata. When the water leaves, it becomes flaccid and opens the stomata.
What part of the plant gives off water vapor through openings called stomata?
Plant leaves have openings called stomata.
Evaporation of water through the stomata?
That is called transpiration; plants do it.
What is a loss of water from the stomata of the leaves called?
It is called transporation
What holes evaporate water from the leaves of plants?
they are called stomata
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).
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.
Does water enters the plant through stomata?
The cells that regulate how much air and water pass through the stomata are called guard cells.
How are the stomata controlled?
The stomata are controlled by two epidermal cells called guard cells. When water flows in, the guard cells swell up and closes the stomata. When the water leaves, it becomes flaccid and opens the stomata.
What part of the plant gives off water vapor through openings called stomata?
Plant leaves have openings called stomata.
What is the small opening under a leaf called?
Stomata
What is the release of excess water vapor through the stomata called?
It is called transpiration.
How the opening and closing of leaf stomata is controlled?
The stomata are controlled by two epidermal cells called guard cells. When water flows in, the guard cells swell up and closes the stomata. When the water leaves, it becomes flaccid and opens the stomata.
Evaporation of water through the stomata?
That is called transpiration; plants do it.
The openings on the underside of leaves -what are they called and what are they for?
They are called stomata (singular: stoma) and they release excess water into the environment through transpiration.
What is it called when water turns to water vapor when heated?
Evaporate?
