Guard cells allows the exchange of oxygen and carbon dioxide in and out of the leaf. This is known as leaf exchange. When guard cells are full of water they swell up and close meaning no oxygen can leave or carbon dioxide can enter, but when the water is taken away from the cell they open up to allow oxygen to exit and carbon dioxide to enter.

Guard cells are specialized cells found in the leaves of plants that control the opening and closing of stomata, which are small pores that regulate gas exchange and water loss. When the guard cells take up water, they swell and cause the stomata to open, allowing for gas exchange. Conversely, when they lose water, the guard cells shrink and the stomata close, reducing water loss.

What is the function of stroma guard cells?

Stroma is a fluid-filled area in the chloroplast that plays a role in the Calvin cycle, where carbon fixation occurs. Guard cells regulate the opening and closing of stomata, controlling gas exchange and water loss in plants. Both stroma and guard cells are essential for proper photosynthesis and plant function.


What is the specialized function of the guard cells?

i believe the function is to protect the stoma


Are there chloroplasts in subsidiary cells?

Subsidiary cells do not typically contain chloroplasts. Chloroplasts are found in the guard cells of plant stomata, where they play a role in regulating gas exchange. Subsidiary cells primarily function in supporting and assisting the guard cells in their role in controlling stomatal opening and closing.


What is the function of guard cells in regulating transpiration and wilting?

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.


What is the difference between a guard cell and other cells?

Guard cells are specialized cells found in plant leaves that control the opening and closing of stomata, regulating gas exchange and water loss. Unlike other plant cells, guard cells have a kidney-like shape and contain chloroplasts to help with photosynthesis. Additionally, guard cells possess a unique structure and function specifically designed for their role in controlling gas exchange.

How many kinds of cells does the lower epidermis have?

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.
