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

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?

The three processes that stop when stomata are closed are photosynthesis, transpiration, and gas exchange. Stomata are small openings on the surface of leaves that regulate the movement of gases into and out of the plant. When stomata are closed, these processes are significantly reduced or halted.

Why do a leafs stomata open and close?

Changes in the osmotic potential of gaurd cells make that stomata open or closed


What are the openings or stomata during the hottest time of the day?

During the hottest time of the day, plants usually close their stomata to reduce water loss through transpiration and to prevent wilting. This helps them conserve water and maintain turgidity.


When do c4 plants keep their stomata closed?

C4 plants keep their stomata closed during hot and dry conditions to reduce water loss through transpiration. By keeping their stomata closed during these times, C4 plants can minimize water loss while still being able to carry out photosynthesis efficiently using their unique carbon fixation pathway.


Why did the stomata from the dark leaf appear different from the light leaves?

Stomata in dark leaves may appear smaller and less abundant compared to light leaves due to reduced photosynthetic activity. The plant may close its stomata in the dark to conserve water and minimize transpiration.


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 is the role of open vs closed stomata in regulating gas exchange in plants?

Open stomata allow for the exchange of gases, such as carbon dioxide and oxygen, between the plant and the environment. Closed stomata restrict this exchange, helping to regulate the amount of water loss and gas exchange in plants.


What type of stomata are seen in aquatic plants open or closed?

C o2


Can a plant makes food if the stomata is closed?

No, plants require open stomata to take in carbon dioxide for photosynthesis. Without the exchange of gases through the stomata, the plant cannot produce food efficiently.
