What role does the flaccid state of plant cells play in maintaining turgor pressure and overall cell function in biology?
The flaccid state of plant cells helps maintain turgor pressure by allowing the cell to take in water and become rigid. This pressure is important for supporting the cell structure and function, such as nutrient transport and maintaining cell shape.
How does a plant cell become flaccid?
A plant cell becomes flaccid when there is a loss of water due to osmosis. This loss of water causes the cell to shrink and lose turgor pressure, resulting in a lack of firmness or rigidity. Flaccidity can be reversed by rehydrating the cell.
How does the concept of flaccid biology relate to the study of plant cell structure and function?
The concept of flaccid biology is important in understanding plant cell structure and function because it refers to the state of a plant cell when it lacks turgor pressure, which is essential for maintaining cell shape and supporting functions like nutrient uptake and photosynthesis. When a plant cell becomes flaccid, it can affect its overall structure and ability to perform vital functions.
Which way would water move if a cell is placed in salt water (a hyper tonic solution)?
The water potential of the outside solution would be lower than the water potential of the cell itself. Therefore, water would pass out of the cell by osmosis (as water moves from a region of higher water potential to lower water potential). An animal cell would shrivel and become crenated. In a plant cell, the cytoplasm would shrink and the cell membrane would come away from the cell wall. This is called plasmolysis and when complete, the cell is said to be flaccid.
What are cells with low internal water pressure called?
Turgor
What is the difference between a flaccid cell and plasmolised cell?
A flaccid cell has lost water and lacks turgor pressure, while a plasmolysed cell has lost so much water that the plasma membrane has detached from the cell wall. Flaccid cells are not necessarily plasmolysed, but plasmolysed cells are always flaccid.

What will be the solute potential and pressure potential of the cell at equillibrium?
At equilibrium, the solute potential of the cell will be equal to the solute potential of the surrounding solution, as there will be no net movement of water molecules. The pressure potential will also be equal to zero, as there will be no additional pressure exerted on the cell membrane. This balance of solute and pressure potentials at equilibrium ensures that there is no net movement of water into or out of the cell.

What is the opposite of a turgid cell?
The opposite of a turgid plant cell is called a flaccid plant cell. A walled cell is flaccid in surroundings where there is no tendency for water to enter. A turgid wall is very form, while a flaccid cell wall is more limp.

What will be zero in a fully turgid cell?
The water potential will be zero in a fully turgid cell because the pressure potential (turgor pressure) is equal and opposite to the solute potential, resulting in a net water potential of zero. This balance prevents further influx of water into the cell.
If a plant cell has a lower water potential than its surrounding environment and if pressure is equal to zero is the cell hypertonic or hypotonic to its environment?
water potential measures the tendency of water to move from one region to another. In the case of osmosis occurring through the membrane of a plant cell, the water potential is the sum of the solute potential and the pressure potential.The question states the pressure potential is nil. Therefore, the water potential is a direct measure of the solute potential.The question also states that the water potential within the cell is lower than that of its surroundings. This means the solute potential within the cell is also lower than that of its surroundings Hence, there is more solutes outside the cell and less solutes inside the cell.This type of solute gradient will cause solvent to move out of the cell. Therefore the cell is hypotonic to its environment.
What happen when a living plant cell loses water through osmosis and what does that phenomenon is known as?
When a living plant cell loses water through osmosis, it becomes flaccid or plasmolyzed, causing the cell to shrink away from the cell wall. This phenomenon is known as plasmolysis. The cell membrane detaches from the cell wall due to the water loss, leading to a loss of turgor pressure and potential wilting of the plant.
What are flaccid cells?
Flaccid cells are plant cells that lack turgor pressure, causing them to become limp and wilted. This can be due to a lack of water or a disruption in the osmotic balance within the cell. Flaccid cells can impact the overall structure and function of the plant.
