Gas enters and exits the stems or leaves of a plant through small openings called stomata. Stomata are primarily responsible for gas exchange, allowing carbon dioxide to enter for photosynthesis and oxygen to exit as a byproduct. Changes in environmental factors like light, temperature, and humidity can affect the opening and closing of stomata to regulate gas exchange.
Carbon dioxide is the gas needed for photosynthesis that enters through the stomata of the cactus stem.

Water does not move through stomata. Stomata are small openings on the surface of leaves that allow for gas exchange. Water moves up the vascular tubes in plants through a process called transpiration, where water is lost through the stomata and creates a negative pressure that pulls water up from the roots.
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.

oxygen
The waste gas produced in photosynthesis is oxygen. This oxygen is released into the environment through tiny pores in the leaves known as stomata. Other organisms, like animals and other plants, can then use this oxygen for their own respiration.
Stomata are tiny pores on the surface of plant leaves that allow for gas exchange, specifically the intake of carbon dioxide and the release of oxygen during photosynthesis. They also regulate the loss of water vapor through transpiration.
Water vapor enters and exits a leaf through small openings called stomata, which are located on the surface of the leaf. When the stomata are open, water vapor can diffuse in and out of the leaf, allowing for gas exchange and regulating the leaf's internal water content.

The stomata on the underside of the leaf allow for gas exchange during photosynthesis.
In animals, gas exchanges are primarily made by diffusion across respiratory surfaces such as the lungs or gills. This is where oxygen enters the bloodstream and carbon dioxide exits. In plants, gas exchange primarily occurs through small openings called stomata on the leaves.
Stomata
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.
