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
DESCRIBE turgor pressure?
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.
What is an example of tugor pressure?
Turgid pressure is the outward pressure that happens in a plant cell when the vacuoles and cytoplasm fill up with water. It pushes the plasma membrane against the cell wall of bacteria, plant, and fungi cells.
Which organelle if empty would cause the plant to welt?
If the organelles called vacuoles are empty inside the plant cells, the cells will implode causing the plant to wilt.Further explanationPlant cells have many organelles out of which one is the vacuole that stores water.When the vacuole is filled with water, it pushes out and exerts an outward pressure against the cell wall and keeps the cells walls firm. This pressure is called the turgor pressure that keeps the plant stiff.When a plant is well-hydrated the vacuoles in a plant is filled with water, and the turgor pressure inside the cells is high, and this turgor pressure keeps the plant stiff. This stiffness helps the plant to stand straight (since they do not have any bone for support against gravity).When a plant gets dehydrated due to lack of water, the plant starts to use the water inside the vacuoles for its vital functions. So water inside the vacuoles starts to exit, and the vacuoles shrink in size.When water inside the vacuoles comes out the turgor pressure reduces thereby causing the plant to wilt.
What are two methods cells use to withstand hypotonic environments?
Plant cells have rigid cell walls that prevent bursting. The pressure of the cytoplasm against the cell wall keeps the plant from wilting and losing its shape. This pressure is called turgor pressure Some protists (such as Paramecium) counteract hypotonicity with the use of contractile vacuoles that pump water rapidly out of the cell.

What is pressure produced by water pushing outward against the cell wall of plant cells?
Turgor pressure

What is turgor pressure and why is it so important?
Turgor supports plants that do not have woody stems. Plants lacking in turgor visibly wilt. The process of osmosis plays an important part in maintaining the turgidity of plant cells.Water leaves and enters the cell by osmosis. If too much water leaves the cell, for example during drought or saline conditions, then turgor is lost and the cell becomes flaccid. As turgor gives the plant rigidity, loss of turgidity results in the plant wilting

How many vacuoles does a plant cell usually have?
Plant cells have just one large central vacuole, functioning as a site for the cells' waste. That is why people claim they can 'smell rain'. A law of nature states that high pressure regions always move into low pressure regions. When a low pressure front is over you, the higher pressure of the plant-cell central vacuoles cause the waste contents to move out of the cells and into the atmoshpere.
What is the different between turgor pressure and diffusion?
The difference of turgor pressure and diffusion is that turgor pressure is an osmotic pressure exerted by the contents of a plant cell against its cell wall; while diffusion is a movement of molecules from an area higher concentration to an area lower concentration.
What do cell walls do in plant cells?
They keep the structure so that the contents of the cell do not spill out.

Why do plant and bacterial cell not burst in a very dilute solution?
Plant and bacteria cells have rigid cell walls that are able to provide pressure against a swelling cell, preventing the cell from bursting.
