when water moves out of cytoplasm by osmosis
is it that the turgid cell has more red pigment than plasmolyzed cell
Plasmolyzed cells may not return to their normal condition even after washing and remounting because plasmolysis typically occurs due to a loss of water in a hypertonic environment causing the cell membrane to shrink away from the cell wall. Rehydration may not reverse this process completely.
In plants this is known as being plasmolyzed when the cell membrane pulls away from the cell wall.
If a plant cell becomes completely plasmolyzed, it means that all of the water has been removed from the cell, causing the cell membrane to shrink away from the cell wall. This can lead to irreversible damage to the cell and ultimately result in the death of the plant cell.
Higher solute concentration outside the cell than that inside causes net loss of water and plasmolysis occurs. This is due to the diffusion of water to areas of higher solute concentration.
when water moves out of cytoplasm by osmosis
In a plasmolyzed cell, the tonicity of the solution outside the cell is hypertonic compared to the cell's internal environment. This causes water to move out of the cell, leading to the shrinkage of the cytoplasm and the detachment of the cell membrane from the cell wall. As a result, the cell experiences plasmolysis, where the cell membrane pulls away from the rigid cell wall due to the loss of turgor pressure.
When a plant cell is placed in a hypotonic solution then plant cell gains water by osmosis there is swelling of the contents of the cell away from the cell wall ,this phenomenon is known as deplasmolyzis
When a cell is no longer turgid in salt water, it is said to be plasmolyzed. In this state, water exits the cell due to osmosis, causing the cell membrane to pull away from the cell wall. This occurs because the external salt concentration is higher than the internal concentration, leading to a loss of turgor pressure.
The cells of lettuce leaf will be plasmolyzed due to exo osmosis.
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.
A cell becomes plasmolyzed when it loses water through osmosis due to exposure to a hypertonic solution, which has a higher concentration of solutes outside the cell than inside. As water exits the cell to balance solute concentrations, the cell's cytoplasm shrinks, and the plasma membrane detaches from the cell wall in plant cells. This process can lead to wilting in plants and reduced cell function. Plasmolysis is reversible if the cell is placed back in an isotonic or hypotonic environment.
