State two functions of stomata.

(N/A) $1$. Gaseous exchange: Stomata facilitate the exchange of gases like $CO_2$ and $O_2$ between the atmosphere and the internal tissues of the leaf,which is essential for photosynthesis and respiration.
$2$. Transpiration: Stomata allow for the loss of water in the form of water vapor from the aerial parts of the plant,a process known as transpiration,which helps in the upward movement of water and minerals from the roots.
