If they didn't, one virus could kill of an entire species.
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.
Guard cells contain chloroplasts, which are responsible for photosynthesis, while other epidermal cells do not typically contain chloroplasts. Chloroplasts are important for the production of sugars and energy through the process of photosynthesis in guard cells.
Stomata open and close in response to changes in turgor pressure within the guard cells. When guard cells take up water, they become turgid and the stomata open to allow gas exchange. Conversely, when guard cells lose water, they become flaccid and the stomata close to prevent water loss.
A stoma is simply the space between two cells called guard cells.The guard cells are specialized cells of the leaf's epidermis. The guard cells have unevenly thickened walls. When their vacuoles contain the maximum amount of water, turgor causes the cells to bend, leaving a space, the stoma, between them.When the osmotic pressure falls, the cells partially collapse, like partly-deflated balloons, closing the stoma.The variations in turgor in guard cells are brought about by varying concentrations of potassium ions in the cells.
The lower epidermis typically consists of a single layer of cells, mainly containing guard cells, subsidiary cells, and stomata. Guard cells control the opening and closing of stomata to regulate gas exchange and water loss in the leaf. Subsidiary cells provide support to the guard cells in carrying out their function.

the function of guard cells are that they control the opening and closing of the stoma

When water flows into the guard cells, they become turgid, causing them to swell and curve away from each other. This opening of the guard cells creates an opening of the stomatal pore, allowing for gas exchange and transpiration to occur.
No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated
No, not all plants have guard cells. Guard cells are specialized cells found in the epidermis of leaves and stems of plants, particularly in vascular plants, that control the opening and closing of stomata. Non-vascular plants like mosses and liverworts do not have true vascular tissue or stomata with guard cells.
The specialized epidermal cells surrounding the guard cells are called subsidiary cells. These cells play a crucial role in the functioning of the guard cells by assisting in the regulation of stomatal opening and closing, which is essential for gas exchange and transpiration in plants. They help maintain the turgor pressure in guard cells, thereby influencing their movement.
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 guard cells.
Guard cells contain chloroplasts, which are responsible for photosynthesis, while other epidermal cells do not typically contain chloroplasts. Chloroplasts are important for the production of sugars and energy through the process of photosynthesis in guard cells.
