Stomata (stoma)

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.
Gases And Oxygen
Through the stomata, (holes in leaf epidermis) these holes have guard cells which open and close and allow CO2 to enter the plant. The CO2 is then filtered through the spongy mesophyll where it can then be accesssed.
The water is taken in by the roots. The carbon dioxide travels through tiny holes, called stomata (singular stoma) to get into the leaf.

the leaf has super little holes. The holes breathe in the carbon dioxide.

The water evaporates through the stomata during transpiration. The stomata are very small holes on the surface of the leaf.
