What's the funcion of the stoma and the guard cells in plant leaves?
Guard cells are able to control how open or closed stomata are by changing shape. The gas exchange occurs when stomata are open facilitates photosynthesis
What is the cell that controls the size of a stoma?
It's actually the guard cells. Water vapor does go through it, though.
What is the cell that makes up the stoma?
The two guard cells one either side contract to open and close stoma.
Each stoma is composed of?
2 guard cells
What sausage-shaped cells control the size of the openings that allow carbon dioxide and oxygen to move into and out of a leaf?
The guard cells of a stoma perform this function.
What is the of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
What the function of guard cells?
the function of guard cells are that they control the opening and closing of the stoma

How does the structure of guard cells relate to the function of guard cells?
control the size of the openings called stoma the stoma allow gases such as carbon dioxide and oxygen to move into and out of the leaf
What is the role of guard cells do in the leaf?
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
What is the function of guard cells in regulating gas exchange in a leaf?
Guard cells are on the surface of plant leaves and surround each stomata (small pores all over the leaf surface). Stomata control the release of gases, including water vapor. During a drought plants occasionally look droopy but still alive, the plant looks wilted because its guard cells are preventing loss of moisture from the stoma (plural of stomata). When defining stomata, it is made of two parts: the pore (opening) itself, and the (2) guard cells around it.
What is the cell that makes up the stoma?
The two guard cells one either side contract to open and close stoma.
Explain how turgor pressure in a guard cell helps during photosynthesis?
Turgor pressure can cause a guard cell to close or open. As the guard cells take in water, it becomes turgid, causing the guard cells to bow, causing the stoma to open. By allowing the stoma to open, gases are able to enter. This is important because since gas rises, it allows CO2 to be captured, which is an important source for photosynthesis. It also allows gas exchange; a product of photosynthesis is oxygen, which then is allowed to be released into the environment through that opening. However, this causes water to be released, which is also an important resource for the photosynthesis. On the other hand, if the cells become flaccid, there is less pressure on the guard cells, causing the stoma to close. This allows the plant to conserve its water and carbon dioxide.
What is the function of the guard cells in regulating gas exchange in a leaf?
The stoma opens and closes to allow gas exchange. The Guard cells are located around the stoma and regulate the opening and closing of the stoma.
Where are guard cells found?
In pairs on the underside of leafs. They control the flow of gases into and out of the leaf. The two of them are called a stoma.
How is the opening and closing of stomata controlled?
The guard cells controll the opening and closing of the statoma!
