Both play part in allowing gases in and out, esp carbon dioxide which is needed for photosynthesis. Stoma, by being a pore; Guard cell, by opening (becoming turgid) and closing (become flaccid) when necessary. They are also both necessary for the leaf's survival.

How do gases enter and escape from leaves?
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.
What does a labeled guard cell look like?
A labeled guard cell typically contains a nucleus, chloroplasts, and a distinct shape that resembles a bean or kidney. These specialized cells are found in pairs surrounding stomata on plant leaves and regulate gas exchange and water loss through their opening and closing. The labels often point out key structures such as the nucleus or chloroplasts.
How does a guard cell look like?
I don't know, except for the fact that they wouldn't taste very good in a salad. Why don't you look this up on a scientific website instead of pining for answers on Ask.com? That's pathetic.
Do all cells look like cheek cells?
yes.
What did chloroplasts look like in the various cells?
In cells where they are present chloroplasts look like small green dots inside the cell when viewed with a microscope.
What cell in a leaf are like a balloon?
The stomatal guard cells are like balloons in a leaf. They are specialized cells that regulate the opening and closing of the stomata, which are small pores on the leaf surface that allow for gas exchange. When the guard cells swell with water, they change shape and cause the stomata to open.
What is the function of guard cells in regulating gas exchange in a leaf?
Guard cells are on the surface of plant leaves and surround each stomata (small pores all over the leaf surface). Stomata control the release of gases, including water vapor. During a drought plants occasionally look droopy but still alive, the plant looks wilted because its guard cells are preventing loss of moisture from the stoma (plural of stomata). When defining stomata, it is made of two parts: the pore (opening) itself, and the (2) guard cells around it.

What do stomata look like?
Stomata are tiny pores found on the surface of leaves and plant stems. They typically consist of two specialized cells, known as guard cells, that surround the pore and control its opening and closing. Under a microscope, stomata appear as small openings, often surrounded by the guard cells.
What does an open stomata look like?
very funny looking

Function of leaf stomata?
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.
What happens to plants when their stomata is closed?
When a plant's stomata are closed, it restricts the exchange of gases like carbon dioxide and oxygen with the environment. This can affect the plant's ability to photosynthesize and can lead to a decrease in growth and production of sugars. Additionally, closed stomata can help the plant conserve water during times of drought or stress.

How do plants get rid of waste product?
Plants do not excrete waste materials from their cells at all. Instead, plant cells possess an organelle (a cell sized organ) called a Central Vacuole in which the plant cell deposits all waste products from chemical processes within the cell. The central vacuole is filled with waste products until either the cell or the plant dies, it does not "excrete" any sort of waste. Alternately you can look at it this way: Sugar is one of the factors of plant waste. The plant stores that, and uses it for energy. Second is oxygen. Oxygen escapes by cells called guard cells. When the stomata (the space between the guard cells) gets full, the guard cells swell open and release extra water, and oxygen.
Why are stomata so close together?
Stomata Stomata are responsible for allowing gas exchange between the inside of the leaf and the atmosphere. A stoma is the singular and stomata is the plural form. When viewed with a microscope, they often look like coffee beans. There are more than 32 stomata in the image of the Western Sword Fern leaf, to the right. Carbon dioxide (CO₂), oxygen (O₂), and water (H₂0) commonly move in or out via the stomata. While gas exchange occurs, carbon (C) stays inside the leaf as a building block for the plant. Often, stomata are open during the day when photosynthesis is taking place and closed at night when it stops. By doing so, plants don’t lose too much water. If the stomata are open, gasses diffuse from areas of higher concentration to lower concentration. If photosynthesis is occurring the CO₂ higher concentration is outside the leaf. For H₂0 and O₂ the area of higher concentration is inside the leaf. This process is depicted in an animated clip prepared by Carnegie Institute for Science. A common misconception that students have is that the stoma’s size can keep out large molecules and just let in the little molecules like CO₂ and H₂0. A stoma is on the order of 10-6m, while a CO₂ molecule is on the order of 10-10m. If we pretend that a stoma opening is one meter across, then the CO₂ molecule would be one tenth of a millimeter in size. Each stoma is made of two guard cells. When these guard cells are swollen with water, they create an opening between them, the stomatal pore. Gas exchange occurs via the pore. When the guard cells are flaccid they lay close together, thus closing the stomatal pore. Plants that are “dicots” have kidney shaped guard cells and plants that are “monocots” have dumbbell shaped guard cells. Normally stomata open in the morning and close during the night. However, not all plants open their stomata during the day. Some plants such as cacti and succulent plants open their stomata at night and close them during the day, in order to prevent losing too much water. Stomata are usually found on both the top and the bottom of a leaf. Many plants have more stomata on the underside of the leaf. However there are exceptions, monocots, like grasses, have similar numbers on both the top and the bottom. Plants whose leaves rest on the surface of the water, like water lilies, often have very few stomata on the wet underside of their leaves. Lenticels Stomata are not the only way for plants to exchanges gases with the air. Plant roots, stems, bark, and fruits have lenticels on their outer surface. These allow oxygen in and carbon dioxide out, as the plant respires. They do not open and close, the way that stomata do. Examples of lenticels are the little spots on pears and the horizontal stripes on cherry tree bark. Stomata Printing Scientists make prints of stomata in order to easily see the surface of a leaf under the microscope. This video shows the process that we outline below. If you want to make the stomata or the locations of the stomata a surprise for your students, do not show it to the students before they begin, as it contains spoilers. The video also incorrectly states that the cells from the surface of the leaf are pulled off. Instead the nail polish is removed from the surface of the leaf. It is an impression of the leaf surface. The nail polish is just like plaster poured into a footprint in sand. Some leaves work better than others for making prints. We find that smooth, sturdy leaves work well. We run into difficulty if leaves are very delicate or are covered by lots of hair. For this reason we suggest that you try your leaves out first or let students know that the method may not work for every leaf. You can also try this method with dried leaves.
What will an epidermis cell look like?
If it is a upper epidermal cell then it will looktransparentclose fittingrectangulara horizontal shapeThe upper epidermal cells are transparent and close fitting, containing no chloroplasts, which are present in other leaf cells. They allow light to pass straight through them. The epidermis is covered by a waterproof cuticle, which reduces water loss from the leaf, since it is a waxy substance.If it is a lower epidermis cell then it will look like cells covered in tiny pores (holes)The lower epidermis has tiny pores (holes)in it's surface called stomata.These are very important for the leaf to exchange gases with the air. The stomata pores can be opened or closed by special cells on either side of the pore called guard cells. thes sausage shaped ceel are green and are thae only epidermal cells to contain chloroplasts
