On a cellular level, a plant cell's cell wall restrains turgid cells. The cell maintains a slightly hypertonic solution within the cell to cause water to diffuse in by osmosis. The cell is "pressurized" in a sense by the incoming water, and would burst if it wasn't contained by a cell wall.
On a molecular level, a plants cell membrane contains "pumps" or "gates", specialized proteins that collect metabolites and other ions from the intercellular space and concentrate them within the cell causing water to diffuse in through the membrane by osmosis.
On a plant organ level, stomata reduce the loss of water during the day by typically staying closed, while opening at night (when cooler and more humid conditions persist) to allow uptake of CO2. This positive control keeps th plant from losing too much water which would cause it to wilt (lose turgor).
There is much more, but you get the general idea.

What else can I help you with?
Turgor pressure occurs in what kind of solution?
Turgor pressure occurs in a hypotonic solution where the cell's cytoplasm has a higher solute concentration than the surrounding environment, causing water to flow into the cell and create pressure against the cell wall.

What cell organelle is most affected by turgor pressure?
The cell organelle that is most affected by turgor pressure is the central vacuole. Turgor pressure helps maintain the rigidity of plant cells by pushing the plasma membrane against the cell wall, which is facilitated by the water-filled central vacuole. Decreased turgor pressure due to water loss can cause wilting in plants.
Why aren't animals capable of turgor pressure?
Short answer: we do not have cell walls in our cells as plants do. The cell wall is required so that the turgor pressure has something to push against. Since we do not have cell walls, this is impossible.
The internal pressure of a plant cell is called what?
turgor pressure, also turgidity, is the main pressure exerted by cell contents against the cell walls in plant cells
How is the internal pressure counter-balanced in plants?
The internal water pressure in plants is countered by the cell wall. This is called turgor pressure.
Turgor pressure occurs in what kind of solution?
Turgor pressure occurs in a hypotonic solution where the cell's cytoplasm has a higher solute concentration than the surrounding environment, causing water to flow into the cell and create pressure against the cell wall.
The pressure in plant cells to make them firm?
The pressure in plant cells that makes them firm is called turgor pressure. It results from the osmotic movement of water into the cell, causing the cell to swell and exert pressure against the cell wall. Turgor pressure is important for maintaining the structural integrity and rigidity of plant cells.
Wilting is counteracted by?
Turgor Pressure
When do plants exhibit turgor pressure?
Plants exhibit turgor pressure when their cells are fully hydrated and the central vacuole is swollen with water, causing the cell to become rigid and firm. This pressure aids in maintaining the structural integrity of the plant and supports processes such as cell expansion for growth.
What is osmotic influx of water?
entry of water that causes turgor pressure in vacuoles of plants

What large structure in plants cell help it maintain turgor pressure?

What is the function of pressure?
Turgor pressure forces plasma membrane against cell walls of plants and bacteria. The pressure is caused by osmosis.
Can plant cells have negative turgar pressure values?
Yes, plant cells can have negative turgor pressure values when there is water loss through transpiration or when the cell loses water due to osmotic gradients. This can cause the cell to plasmolyze or shrink, resulting in negative turgor pressure.
The pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cell?
Turgor pressure is the pressure exerted on the inside of cell walls when water enters the cell through osmosis. This pressure helps maintain the structural integrity and shape of the cell. If the cell becomes too turgid, it can lead to issues like wilting in plants.
What cell organelle is most affected by turgor pressure?
The cell organelle that is most affected by turgor pressure is the central vacuole. Turgor pressure helps maintain the rigidity of plant cells by pushing the plasma membrane against the cell wall, which is facilitated by the water-filled central vacuole. Decreased turgor pressure due to water loss can cause wilting in plants.
