Plants carry on the process of photosynthesis by combining together several ingredients in their leaves. Some of these materials are gaseous( carbon dioxide), some are liquid ( water ), and one is energy ( sunlight ). If one were to look at the anatomy of a leaf, it would be easy to see how these materials are brought to the leaf so that they can form the food. The stomata is the way in which this transfer of ingredients can occur, transferring the CO2, light and water from the surrounding atmosphere in to the plant. In light the guard cells swell, causing the pore to be at its widest, and CO2 diffuses into the leaf and into the cells to be assimilated in photosynthesis. In the dark or under drought conditions the guard cells are not turgid, the stomata are closed and no photosynthesis takes place. Opening of the stomata not only allows CO2 to diffuse into the leaf, but allows water vapor to diffuse out of the leaf. The alteration in the size of the stomata occur in response to a variety of the external stimuli such as light, carbon dioxide concentration and water. The stomata is situated on the underside of the leaf for the reason that if it were on the top side the plant would lose to much water. Because the guard cells are partially light activated, plants under direct sunlight would constantly have their stomata open and would thus lose much water and the plant dying.

These openings in the leaf are for the intake of carbon dioxide and the exhalation of waste oxygen. Moderated by guard cells to open and close as needed.
the function of stomata cell they exchange gases between the inside of the leaf and it's surroundings takes place by diffusion. The stomata cell is green due to cytoplasts.
Stomata
The leaf surface has many tiny apertures called stomata. During respiration oxygen from the atmosphere diffuses into the stomata and then into the cells of the leaf. When carbon dioxide concentration in the cells increases, the stomata opens and releases carbon dioxide into the atmosphere.
stomata
It's called a stoma (plural stomata) and its function is to allow carbon dioxide to enter the leaf for photosynthesis. The guard cells sre responsible for regulating the size of the stoma.
The function of stomata is that they are small openings or pores on the surface of leaves.The function of stomata is to allow gases such as oxygen, water vapor, and carbon dioxide to move around the leaf.

Yes they do! All leaves have stomata, but the lotus's stomata are on the top of the leaf, not the bottom.
A stomata is the openings in the leaf.

Stomata
The lower surface of the leaf has the stomata. You can see the reason for this if you cut a leaf in half from upper side to lower side. The upper portion of the leaf consists of tightly packed cells that are full of chloroplasts for taking in light. The lower half of the leaf is made up of loosely arranged cells. This allows room for air to enter the lower part of the leaf through the stomata and contribute carbon dioxide and take away oxygen. The upper surface of the leaf is covered by the cuticle which prevents dehydration, as such the stomata cannot be located or function on the upper surface
