Stomata open and close in response to pressure within?

Stomata open and close in response to changes in turgor pressure within the guard cells. When guard cells take up water, they become turgid and the stomata open to allow gas exchange. Conversely, when guard cells lose water, they become flaccid and the stomata close to prevent water loss.


How does water get out of a plant?

Water can get out by transpiration through the leafs stomata.


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 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.
