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 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.
How does the stomata density affect the water loss?
When open, the stomata can release water. The more dense or larger the stomata are, the more water they can release.
What causes the stomata on leaves to open?
Photosynthesis
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.
The stomata of leaves are usually open in?
in the day
What regulates the stomata?
The guard cells open and close the stomata as needed.
Why do a leafs stomata open and close?
Changes in the osmotic potential of gaurd cells make that stomata open or closed
What causes stomata to open?
Increase in temperature causes stomata to open. A hydathode is a type of secretary tissue in leaves, usually of Angiosperms , that secretes water through pores in the epidermis or margin of leaves, typically at the tip of a marginal tooth or serration. They probably evolved from modified stomata.

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.
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.
What are the cells that surround the stomata called?
Guard Cells surround the stomata, and enable it to open or shut.
How does the stomata density affect the water loss?
When open, the stomata can release water. The more dense or larger the stomata are, the more water they can release.
