What is the effect of of pure water and of salt water on turgor pressure of the potato strips as compared in control?
Pure water increases turgor pressure in potato strips due to osmosis, as water moves into the cells, causing them to swell and become firm. In contrast, salt water decreases turgor pressure because it draws water out of the cells, leading to plasmolysis and a loss of firmness. Compared to the control (potato strips in isotonic solution), potato strips in pure water will be more turgid, while those in salt water will be wilted and less turgid. This demonstrates the impact of solute concentration on cellular water movement and 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
What is a sentence for the term turgor pressure?
When the turgor pressure is low in a plant it will start to slouch and wilt.
What change will occur if a piece of peeled potato is dropped in a concentrated sugar solution?
The potato may show some shrinking, but the more observable change is loss in mass of the peeled potato. Water will move out of the potato by osmosis. In osmosis, the water moves from the area of higher concentration to the area of lower concentration. There is lower water concentration outside of the potato because of the high amount of sugar dissolved in it. Depending on the concentration differences between the potato and the solution, water loss will continue until an equilibrium is reached. The potato piece will become flaccid (floppy)/plasmolysed, because of the water loss it has suffered. Shrinkage results from loss of turgor pressure in the potato, as a result of it becoming plasmolysed.
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.
Wilting is counteracted by?
Turgor Pressure

How does water affect the appearance of a vegetable?
The amount of water in the cells of a vegetable affect the turgor pressure in the cells. The turgor pressure is how much pressure is in the cells. If the cells of the vegetable do not have enough water, the turgor pressure is low, so the plant wilts, making the vegetable look shriveled or small. If the cells of the vegetable have the right amount of water, the turgor pressure is high enough to keep the plant from wilting, so the vegetable looks healthy. If the cells of the vegetable have too much water, the turgor pressure is very high, and the cells may burst open, making the vegetable look shriveled and small.
How can you tell if a plant has a decreased turgor pressure?
A plant wilts when it has a decreased turgor pressure.
How does a change in turgor pressure cause a plant to move?
It changes it by singing the ball and wiener song
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?
When the turgor pressure is low in a plant it will start to slouch and wilt.
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.
Which pressur is opposite to turgor pressure?
wall pressure
What is the loss of cell pressure known as?
Turgor pressure
