There are cells called guard cells on the tiny pores (stomata) on the underside of a leaf. According to the status of the gases inside the leaf cells, and the outside conditions, the guard cells allow air into the pores. This brings in carbon dioxide and releases oxygen, but also releases water vapor. This transpiration process can be used to cool the leaf as needed.

Where does gas exchange occur in a plant?
in the leaf
Why spongy layer of cells loosely arranged?
So that the cell can breath.
What is the function of a leafs stomata?
Help in gaseous exchange
How does lower epidermis adapt to do it job in the leaf?
In dicot plants the lower epidermis is frequently ruptured by stomata and thus helps in gaseous exchange and transpiration.
How does gaseous exchange with the surrounding occur in land plants?
It is because Co2(carbon dioxide) is transferred to the plant and the plant makes the Co2 Oxygen.
What is the leaf job?
Photosynthesis, gaseous exchange and transpiration

simple diffusion
What allow gaseous exchange between leaf and atmosphere?
Stomata on the underside of the leaf control the passage of gases into and out of the leaf.

The spongy layer in a plant leaf facilitate better gaseous exchange for photosynthesis and respiration.
What negative impact occurs when guard cells closing on the plant leaf?
The gaseous exchange is hampered.
