Guard cells are specialized epidermal cells that surround and control the opening and closing of stomata in plant leaves. They have a unique kidney or bean shape, which allows them to change size when turgor pressure alters due to water movement. Each guard cell contains chloroplasts, enabling photosynthesis and influencing their ability to regulate gas exchange. The cell walls of guard cells are unevenly thickened, which facilitates their movement and the opening and closing of the stomatal pore.
What else can I help you with?
Which structure controls transpiration?
guard cells
Is the specialized structure that surrounds the stomata on the underside of leaves?
guard cells
What cell structure is in the guard cells but not in other epidermal 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.
How does the structure of guard cells relate to the function of guard cells?
control the size of the openings called stoma the stoma allow gases such as carbon dioxide and oxygen to move into and out of the leaf
What is the difference between a guard cell and other cells?
Answer1. Guard cells have chloroplast, epidermal cells do not have.2. Guard cells are much smaller than the epidermal cells.3. The cell walls of guard cells are not uniform, inner walls are thicker than the outer walls. epidermal cells are unformly thin.
What leaf structure adjusts the size of the stomata?
Guard cells, which are specialized cells that surround the stomata, are responsible for adjusting the size of the stomatal pore. When the guard cells take up or release water, they change shape and control the opening and closing of the stomata.
What cells guard the opening and closing of the stomata?
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.
Each stoma is composed of?
Each stoma is composed of two specialized cells called guard cells that control the opening and closing of the pore. This structure allows for gas exchange, such as the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor.
What two structure control and allow the plant leave to cycle oxygen and carbon dioxide in and out of the leaf?
Stomata and guard cells.
What is the of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
What the function of guard cells?
the function of guard cells are that they control the opening and closing of the stoma
The guard cells control the opening and closing of what structure?
The guard cells control the opening and closing of the stomata, which are tiny pores found on the surface of plant leaves that regulate gas exchange and water loss. By adjusting the turgor pressure within the guard cells, the stomata open to allow gases like oxygen and carbon dioxide to enter and exit the leaf.
