stomata
Mesophyll cells
Gases enter and exit a leaf through stomata. These are openings in the epidermis which are regulated by guard cells. Guard cells decide which gases can go in and out. The gas that goes in is carbon dioxide and the gas that goes out it oxygen.
The region in the leaf that has air spaces to facilitate the movement of gasses is the mesophyll region. This region is composed of layers of cells.
Carbon dioxide moves in while oxygen moves out.

Mesophyll cells
The vasculature inside the green leaf moves a number of particles of food, water, minerals and gases.

Respiratory
The stoma (stomata)
Carbon dioxide moves in while oxygen moves out.
Diffusion!
Stomata on the underside of the leaf control the passage of gases into and out of the leaf.
