Oxygen and water vapor are released through the stomata.

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.
Because the stomata (which is the plural for stoma) is the only place where gas exchange can go on, it is located under the leaf.

Stomata is a tiny opening or pore, found mostly on the under-surface of a plant leaf. It is responsible for gaseous exchange between the leaves of plants and the environment.
Oxygen is the waste gas from photosynthesis which passes out through the stomates (stomata).
the gas exchange through stomata because it gives more gas to the plants and to the people that breathe in (NOW SATISFIED)
as the stomata is responsible in gas exchange, and it constantly looses water through it the stomata would die out

Cellular waste is a broad term. The stuff your cells excrete are transported away by different systems. Much of the waste products and useless chemicals end up being filtered out by the kidneys and are then tossed out of the body through urinating. Carbon-dioxide, the waste gas produced by the cellular metabolism, is reabsorbed into the bloodstream and exits through the alveoli in the lungs.
