are you talking about the stomata on leaves?
they are openings usually on the underside of a leaf that allows gases, like CO2 to enter the leaf. they are protected by two guard cells on either side, and the stomata or just stoma, is the actually opening inbetween the guard cells
tell me if that helps

The stomatal cells are present in the leaves of the cells. They consist of an opening known as the stomatal pore that are surrounded by 2 guard cells. These guards cells are thick in the center and thin on the outside. They control the opening and closing of the cell. When the cell is full of water these guard cells swell up and therefore causing the pore to be exposed. This causes water to evaporate, and thus excess water is expelled from the cell. So the stomata regulates the amount of water inside the cell. This is known as transpiration. The process of transpiration cools the plant and regulates its temperature. The process also causes a suction or vacuum (pull). this suction force due to transpiration is the main factor in lifting water and dissolved mineral salts up the plant from the roots to the leaves. This suction force due to transpiration is the main factor in lifting water and dissolved mineral salts up the plant from the roots to the leaves. The water and minerals is used in the process of photosynthesis. The stomata also plays an imporatant role in the exchange of gases. Carbon Dioxide is absorbed and Oxygen is removed. CO2 is necessary for photosynthesis whereas O2 is waste product.

The stomata regulates the level of water and CO2 that can leave or enter the leaf.
When the stomata is open ( the Guard Cells are turgid) the amount of water loss is increased and the amount of Carbon Dioxide that enters is increased. The opposite happens when the stomata is closed (Guard Cells become flaccid). This regulates water movement and loss in the plant and also effects the rate of photosynthesis.

what is the role of the stomata?

Stomata open to let carbon dioxide enter a leaf and to let oxygen go out of the leaf. Water vapor also escapes while stomata are open, and this helps pull more water up through the plant.
