In the day plants use their stomatas to absorb carbon dioxide. However, in the night, plants absorb oxygen instead of carbon dioxide thus they stop their stomatas from absorbing anymore carbon dioxide by closing them

∙ 12y agoThey are open to bring carbon dioxide into the plant for photosynthesis, which requires sunlight. This process loses water to the surrounding air through the stomata. When the plant can not preform photosynthesis at night it closes the stomata to conserve water.

∙ 13y agobecause the nuclear ions which are produced by the plant (although in very little quantity) cannot escape and so the stomata close
Wiki User
∙ 11y agoThe stomata are closed during dry period because this way they won't loose any water.

What is the openings on the underside of leaves?
stomata =Specialized passages through the cuticle that enable plants to exchange gases.
Is loam usually light or dark?
dark
What ions involve the opening and closing of stomata?
Potassium ions, they contribute to the control of turgidity of guard cells, and thus the opening and closing of stomata.
Do all plants have the same amount of stomata?
No, not all plants have the same number of stomata. Stomata numbers vary among different plant species and can be influenced by environmental factors.
When would guard cells close the stomates?
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.
Are the stomata usually open or closed during photosynthesis explain?
They are usually closed during these periods so that they wont loose any water because of transpiration.
Which 3 processes stop if stomata is closed?
Diffusion, Respiration & Photosynthesis. These 3 processes will stop if stomata is closed.
When do c4 plants keep their stomata closed?
The C4 plants tend to keep their stomata closed during the day to conserve water.
What is the advantages of a stomata being closed at night?
Primarily, and in C3 plants, the stomata closed at night retards the loss of moisture when photosynthesis is not taking place.
What part of the day would the stomata be closed?
midday
Will the stomata of a wilted plant be open or closed?
it is closed so no further water can be lost
Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
Which factor limits phtosynthesis when the stomata are closed?
Carbon Dioxide.
What are the openings or stomata during the hottest time of the day?
Closed.
C4 plants conserve water by?
opening their stomata and admitting C02 only at night
What is a guard cell of a plants?
The guard cells flank the stomata and are the means by which the stomata are opened and closed. To take in CO2 and to expel O2 and water. Can close to conserve water if needed and this process usually happens at night when photosynthesis, the light reaction, is suspended.
What type of stomata are seen in aquatic plants open or closed?
C o2
