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.
No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated

Epidermis
In the palisade cells, spongy cells, and guard cells.
Guard cells in the lower epidermis are the only cells with chloroplasts in a leaf because they play a crucial role in regulating gas exchange and water loss through the stomata. Chloroplasts allow guard cells to photosynthesize and produce sugars, which provide the energy needed for stomata opening and closing. This specialization ensures efficient control over transpiration and photosynthesis in leaves.
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.
