What causes the stomata on leaves to open?
Stomata open in response to environmental factors such as light intensity, CO2 levels, and humidity. Light triggers the production of a hormone called abscisic acid, causing the guard cells around the stomata to swell and open. Conversely, in darkness or when environmental conditions are unfavorable, the stomata close to prevent water loss through transpiration.
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.
Specialized structures that allow gas to enter and leave leaf?
Stomata
Why don't plants keep their stomata open all the time?
Plants do not keep their stomata open all the time because it would lead to excessive water loss through transpiration. Stomata need to close to prevent dehydration and maintain proper water balance within the plant. Additionally, closing stomata helps plants conserve energy and regulate gas exchange more efficiently.
When are the stomata of leaves usually open?
Depending on the environment of the plant, stomata will open and close at different times. In hot, dry environments stomata will open around dusk and dawn to minimise water loss. In Wet environments stomata will open during the day as needed

Would stomata open or close if CO2 concentration decreased?
close
The tiny pores or openings in leaves that take in the carbon dioxide are called?
Those pores are on the bottom of the leaf surface and are called stomata (singular stoma). They have guard cells that open and close the pore based on several conditions in the environment.
What will happen if stomata were kept open all the time?
The leaves would dry out
What regulates the stomata?
The guard cells open and close the stomata as needed.
Would the stomata open or close if the CO2 concentration decrease?

Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed

What would happen to plant if its stomata stayed open all the time?
It would dehydrate because it would transpire too much.
