Any oxygen taken in through the stomata is inconsequential, for it forms no function for the plant. Similarly for the nitrogen and the argon, etc.
The CO2 however is important, for this may be reacted by the plant with the hydrogen it obtains through the photosynthesis process. This is then used to manufacture complex carbohydrates. The magic of photosynthesis lies in the breaking of the water molecule into hydrogen and oxygen. The oxygen is discharged as a waste gas.
There are other photosynthesis processes known, other than those based on chlorophyll. Seaweeds for example use red, green, and brown photosynthesis processes, each with its own chemistry.
For further information on the types of photosynthesis, have a crack at 'photorespiration' in a reference source such as wikipedia.
stomata
If the plant is devoid of stomata the process of photosynthesis and respiration won't occur within the plant due to diffusion of oxygen and carbon dioxide not taking place.

it gives the leaf food, carbon dioxide enters through tiny holes called stomata, Oxygen leaves plant through stomata. This is called respiration
Carbon dioxide enters through a plant's stomata because it is a key component needed for photosynthesis, which is the process by which plants convert carbon dioxide, water, and sunlight into glucose and oxygen. The stomata are small openings on the surface of leaves that allow for gas exchange, with carbon dioxide entering the leaf and oxygen exiting.
stomata
Stomata are tiny openings on the surface of plant leaves that regulate gas exchange. They allow for the uptake of carbon dioxide for photosynthesis and the release of oxygen and water vapor. Stomata open and close to control the movement of gases, water, and nutrients in and out of the plant.
Oxygen leaves the plant through small pores on the leaves called stomata during the process of transpiration. Carbon dioxide enters the plant through the same stomata during photosynthesis, where it is converted into glucose for energy.
Carbon dioxide enters plant cells through small openings on the surface of leaves called stomata. The stomata open to allow carbon dioxide to diffuse into the plant cell during photosynthesis, where it is used to produce glucose and oxygen.
These structures are called stomata, which are small pores present on the surface of plant leaves. Stomata open to allow carbon dioxide to enter the plant for photosynthesis and close to prevent excessive water loss. Oxygen produced during photosynthesis exits the plant through these stomata as well.
If the plant is devoid of stomata the process of photosynthesis and respiration won't occur within the plant due to diffusion of oxygen and carbon dioxide not taking place.

Carbon dioxide and oxygen enter and leave the plant through the stomata, on the underside of leaves.
small holes on a leaf which we cannot see are called stomata.Through stomata plant take carbon dioxide and give out oxygen
stomata
In addition to carbon dioxide, oxygen and water vapor also pass through the stomata. Oxygen is a byproduct of photosynthesis and diffuses out of the plant, while water vapor is a product of transpiration.
