When water leaves the plant cell, for example in osmosis, the pressure (created by the water) of the protoplast pushing against the cell wall will decrease. This pressure is known as turgor pressure and decreasing it will cause the cells to become soft/flaccid and so the plant will begin to wilt more and more as the turgor pressure decreases.
Turgor pressure is the pressure exerted by the fluid (usually water) inside the central vacuole of plant cells against the cell wall. This pressure helps to maintain the rigidity and shape of the plant cell. When a plant cell is well-hydrated, turgor pressure will be high, resulting in a turgid cell.
Turgor pressure pushes the plasma membrane against the cell wall of plant, bacteria, and fungi cells. An example of turgor pressure is osmosis which causes water to flow from an area of low solute concentration to an area of high solute concentration until the two areas are equal.
Since plant cells have a rigid wall, when water loads into a plant cell pressure can build up without the membrane bursting. The pressure from this overload and expansion of the inner cell membrane is called turgor pressure. Turgor pressure can be observed in swollen cells under microscopic examination.
"Definition: Turgor Pressure: also called turgidity, is the main pressure of the cell contents against the cell wall in plant cells. Turgid plant cells contain more water than flaccid cells and exert a greater osmotic pressure on its cell walls.
Turgor is a force exerted outward on a plant cell wall by the water contained in the cell. This force gives the plant rigidity, and may help to keep it erect. Turgor can result in the bursting of a cell."

So, basically it's water pressure on the cell wall.
Turgor pressure helps describe the amount of water in a plant and how it relates to its firmness. A plant with low turgidity is low on water, or perhaps just naturally soft and flexible.
Turgor pressure is the pressure exerted by the water that is inside the cell, against the cell wall. This helps the plants stand upright.
The term turgor pressure refers to the process of a plasma membrane being pushed against a cell wall. This process happens in plants, bacteria, and fungi cells.

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
What is a sentence for the term turgor pressure?
Turgor pressure is the pressure inside a plant cell that keeps it firm and rigid, like a fully inflated balloon.
What is The pressure exerted against the cell membrane and cell wall known as?
The pressure exerted against the cell membrane and cell wall is known as turgor pressure. It is generated by the osmotic flow of water into the cell, causing the cell to become rigid and maintain its shape.
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.
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.
Wilting is counteracted by?
Turgor Pressure
How can you tell if a plant has a decreased turgor pressure?
A plant wilts when it has a decreased turgor pressure.
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
Does turgor pressure in a hypertonic solution increase or decrease?
more solutes = less osmotic pressure = decreased turgor pressure
What is a sentence for the term turgor pressure?
Turgor pressure is the pressure inside a plant cell that keeps it firm and rigid, like a fully inflated balloon.
What is the structure associated with resisting turgor pressure?
The plasma membrane is the structure associated with resisting turgor pressure.
The pressure that builds in a plant cell as a result of osmosis is called?
The pressure that builds in a plant cell as a result of osmosis is called turgor pressure. This pressure is important for maintaining the rigidity and shape of plant cells.
Which pressur is opposite to turgor pressure?
wall pressure
What is the loss of cell pressure known as?
Turgor pressure
Using knowledge of turgor pressure explain how the plant might be revived?
To revive a wilted plant, you can water it to replenish lost turgor pressure. When a plant lacks water, its cells lose turgor pressure, causing wilting. Watering the plant will allow the cells to take up water, regain turgor pressure, and become rigid again.
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.
