Control the opening and closing of the stomata.
Guard cells contain chloroplasts, which are responsible for photosynthesis, and a large central vacuole that regulates the opening and closing of stomata. These organelles are absent in the skin cells of a leaf.
The guard cell of stomata look like a balloon when it is turgid. Two such cells form the pore of the stomata. When both guard cells of a stomata are deflated by exo-osmosis the stomatal pore is closed.
The guard cells are specialized cells that control the opening and closing of the stomata in plant leaves. They can change shape to regulate the exchange of gases and water vapor between the leaf and the surrounding environment.
They are the pair of cells that surround the stomata (pores on the underside of leaves) They can change shape to open or close the stomata. Most plants open their stomata during the day (to allow co2 to enter for photosysthis) and close them at night. However cacti open their stomata during the night to reduce water loss, and have to use stored co2 for photosysthesis.
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.
No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated

In the palisade cells, spongy cells, and guard cells.
Guard cells contain chloroplasts, which are responsible for photosynthesis, and a large central vacuole that regulates the opening and closing of stomata. These organelles are absent in the skin cells of a leaf.
Pores, known as stomata, are surrounded by two specialized cells called guard cells in the epidermis of a leaf. These guard cells control the opening and closing of the stomata, regulating the entry of carbon dioxide for photosynthesis and the release of oxygen and water vapor. They help to maintain the balance of gas exchange and water regulation in the leaf.
Palisade cells, spongy mesophyll cells, and guard cells contain chloroplasts in leaves. Palisade cells are located in the upper leaf epidermis, spongy mesophyll cells are below the palisade layer, and guard cells surround the stomata.
in guard cells......believe me!
The interaction between guard cells and a leaf opening would not be involved in the process of photosynthesis. Instead, the interaction between guard cells and a leaf opening is responsible for regulating the opening and closing of the stomata, which affects gas exchange and water loss in plants. This helps to maintain proper hydration and gas balance within the leaf.
The guard cell of stomata look like a balloon when it is turgid. Two such cells form the pore of the stomata. When both guard cells of a stomata are deflated by exo-osmosis the stomatal pore is closed.
Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
The stomata are the pores and the guard cells control the opening and closing of these pores.
