Guard cells would close the stomata to prevent excess water loss through transpiration, normally when the weather is extremely hot or there is a lack of ground water. This is a regulatory mechanism to prevent dehydration.

∙ 9y agoA guard cell would close the stomata in response to a loss of water in the leaf, as an attempt to conserve water. The stomata are more often closed in high humidity when the water pressure inside the leaf is low, meaning it is needed inside the leaf. Light intensity and carbon dioxide concentration may be other factors determining whether the stomata are closed or open. The last reason that is known to cause the closing of stomata is the loss of solutes in the leaf, such as chloride or inorganic ions.

What would happen if the guard cells are closer together?
The stomata would be narrower, thus osmosis would occur less, thus photosynthesis would be less. The stomatal pore will become narrower. Gaseous exchange to and fro stomata will be reduced. This will affect the rate of photosynthesis in green plants.
What would happen if the was gone?
Iron is a major component of red blood cells. The oxygen you breathe bonds to the iron in your red blood cells. If you had no iron in your body you would likely die.
Which is the main reason cells are replaced in the body?
because if they didnt get replaced then you would lack the cells. and you would die. i think.
What would happen if microorganisms had not been discovered?
What was the world like before Pasteur? Our understandings of the disease process is closely tied with the discovery of microorganisms. So one guess would be that more of us would be dying of disease in the absence of knowledge of microorganisms.
What are the there listed points of the cell theory?
The three listed points of the cell theory would be that cells are the building blocks of life, all life is composed of cells, and all cells come from preexisting cells. These were found by different people.
Under what conditions would the guard cells close the stomates?
To prevent excess water loss through transpiration - normally when the weather is extremely hot or there is a lack of ground water. This is a regulatory mechanism to prevent dehydration.
What do guard cells close to prevent excess water loss?
The guard cells provide the plant with the control mechanisms. The guard cells control the opening and closing of the stomata in plant tissue. Without guard cells, the plants would not be able to control its water intake.
What is the gatekeeper cell?
That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
Function of guard cells?
The guard cells surround each stoma in a plant cell. They regulate the opening and closing of stomata to facilitate gas exchange and control transpiration in plants.
Shannon is a botanist who observed stomatal closing of plants under daytime drought conditions Why would the stomata close?
To prevent loss of water from guard cells
What would happen if the cells of a developing plant did not differentiate into guard cells?
If they didn't, one virus could kill of an entire species.
The effect of CaCl2 solution on the opening and closing of stomata?
sugar solution does effect the opening and closing of stomata. when stomata is treated with sucrose solution, the guard cells will loss its water content as sucrose solution is more concentrated. water will moves from higher water potential (low concentrated) to low water potential (high concentrated). thus, water moves out from guard cell to its surrounding cell. when cell loss the water, it later lost its turgidity and shrink. the shrink cell eventually become flatten and close the stomata pore. . =)
What would happen if the cell of a developing plant did not differentiate into guard cells?
the cell will died
When would plant cells need to close or partially close their stomata?
At night or when there is no sunlight available.
An analogy for ribosomes in a football field?
the ribosomes delivers protein to the cells so the ribosomes would be the guard.
The interaction between guard cells and a leaf opening would not be involved in what?
The interaction between guard cells and a leaf opening would not be involved in the process of photosynthesis. Instead, the interaction between guard cells and a leaf opening is responsible for regulating the opening and closing of the stomata, which affects gas exchange and water loss in plants. This helps to maintain proper hydration and gas balance within the leaf.
Which structure is a gatekeeper controlling what goes in and out of the cell?
That would be the "guard cells". The stoma is an opening on the underside of many leaves and each stoma is bordered by a pair of guard cells that open and close the pore to allow for "transpiration" (the passage of water in either gaseous or liquid form into or out of the leaf). In hot, dry weather, the guard cells close to prevent water loss. In humid weather, the guard cells allow the pore to open and water can enter.
