When it's light, the plant needs CO2 (carbon dioxide) for photosynthesis, so the stomata opens.
At night (darkness) they close to conserve water.

Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
How does the ability to open and close the stomata aid in the survival of the plant through different types of weather?
How does the ability to open and close the stomata aid in the suninal of he plant through different types of weather
. CAM plants close their during the day and open them at night?
stomata
3 What is the function of stomata in photosynthesis?
Stomata are tiny openings on leaves that act as mouths. They open and close to release and take in moisture.
How guard cell open and close?
guard cells open when water flows into them because they swell and they close when it shrinks aswater flows out of the stomata
What regulates the stomata?
The guard cells open and close the stomata as needed.

Would stomata open or close if CO2 concentration decreased?
close
What structures open or close the stomata?

Stomata are tiny openings on leaves that act as mouths. They open and close to release and take in moisture.
What is the role of a stomata and guard cells?
Through the stomata carbon dioxide diffuses into the plant and oxygen and water vapor diffuse out of the plant. Guard cells control the opening and closing of the stomata. Used in arid climates to control water loss for instance.
How guard cell open and close?
guard cells open when water flows into them because they swell and they close when it shrinks aswater flows out of the stomata
What is the breathing organ of plant?
The Stomata is the small opening on the underside of the left that allows for the absorption of CO2. A plant can open and close the stomata to help cut down on moisture loss.
Would the stomata open or close if the CO2 concentration decrease?
Opening and closing of stomata is regulated by concentration of water in guard cells. When transpiration is required, water reaches the guard cells and they swell up. This opens the stomata's pore. When they are not required to be opened, water is not present in guard cells and they shrink causing stomata's pore to close.
