i believe it is not true. the desert plant cells close during the daytime and open at night
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.
Guard cells form the stomata. They can open and close to regulate the exchange of gases such as oxygen and carbon dioxide, as well as control water loss in plants.
The cells that make up the stoma are known as guard cells. These specialized cells are responsible for regulating the opening and closing of the stomata to control gas exchange and water loss in plants.
A chain of events leads to an increase in the concentration of sugar in the cell sap in the vacuole of guard cell. osmotic potential of cell sap decreases and guard cells withdraw water from the neighboring cells. this increases turgid pressure of the guard cells it swells up.the swelling of the outer wall causes the guard cells to curve away from each other so increases the gap between them stomata opens). and when guard cells lose water, they become flaccid and comes closer thus stomata closes.
Guard cells play a crucial role in regulating transpiration and preventing wilting in plants. They control the opening and closing of stomata, small pores on the surface of leaves. When the guard cells uptake water, they swell and the stomata open, allowing gas exchange for photosynthesis and transpiration. Conversely, when guard cells lose water, they shrink and close the stomata, preventing excessive water loss and wilting.
The guard cells of non desert plants simply contract a bit but do not close. Desert plants close their guard cells.

If by guard cells you mean the ones located in plants, they open and close the stomata to control water loss :)
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.

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

Guard cells open and close stomata to regulate gas exchange and control water loss in plants. They respond to environmental signals like light, humidity, and carbon dioxide levels to maintain optimal conditions for photosynthesis while preventing dehydration.
