The guard cells become turgid when the plant is well hydrated. The turgidity changes their shape to open the stomata. When the guard cells are flaccid, the stomata close and the plant conserves water.

If you want to be specific, Eudicots are kidney shaped, whereas Monocots are more dumb-bell shaped.

∙ 15y agoThe internal water pressure (turgor) changes the shape of guard cells to open or close the stoma in leaves. The change in turgor is a result in a drop of C02 as carbon is bound into sugars.

Which cells in your body can change their shape?
White blood cells in our body change their shape.
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 cells regulate the amount of water vapor that passes through the stoma?
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.
What cells guard the opening and closing of the stomata?
Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing their guard cells using osmotic pressure. Guard cells and adjacent subsidiary cells are involved in opening and closing of stomata.
What are the names of the specialized cells that control the aperture of the hole of the stomata?
These are called the guard cells.
What is the role of guard cells do in the leaf?
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.

How do shapes vary in shape?
Cells can take on a solid shape, have no shape at all, or change shapes.
What happens to the xylem system during drought when water is scarce?
Falling moisture levels in the leaf cause the guard cells to change shape, closing the stomata. This reduces water loss from the plant.
Which animal that changes it's shape?
frogs change sex and snake change skin but no animal changes shape their cells do

Where leaf pore guard cells found?
They are cells in the leaf epidermis, located arond the stomata. A pair of guard cells open and close each stoma (pore) for gas exchange and transpiration. They are different in shape from the rest of the epidermis cells, and unlike other epidermis cells they also contain chloroplasts.
Shape-shifting cells?
Cells in some animals that allows for the animal to change its physical form at will.
Which structure controls transpiration?
guard cells
Why do white blood cells need to be able to change shape in order to accomplish their function?
White blood cells need to be able to change shape so that they can move into and out of the blood stream. This process is known as diapedesis.
