Is a guard cell a tissue a organ or a cell?
A guard cell is a type of cell found in the epidermis of plant leaves. It is not a tissue or an organ; rather, it is a specialized cell responsible for regulating the opening and closing of stomata to control gas exchange and water loss in plants.
What do the features on a guard cell do?
Guard cells are specialized cells located on the surfaces of plant leaves and stems that regulate the opening and closing of stomata. These cells control gas exchange by changing shape in response to environmental conditions, allowing carbon dioxide to enter for photosynthesis while minimizing water loss through transpiration. The features of guard cells, such as their flexible cell walls and the presence of chloroplasts, enable them to respond to light, humidity, and internal water levels effectively. This regulation is crucial for maintaining the plant's overall health and metabolic functions.
What is the function of a vacuole in a Guard Cell?
Vacuoles in guard cells help regulate the movement of water and ions in and out of the cell, which in turn affects the opening and closing of the stomata. The vacuole can change its volume to control the turgidity of the guard cell, leading to the opening and closing of the stomatal pore for gas exchange.
What two features can be found in the plant cell but not in the animal cell?
cell wall
How plants open and close the stomata?
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.
