Collapse of a walled cell's cytoplasm due to the lack of water.
Plasmolysis= contraction of the protoplast of a plant cell as a result of loss of water from the cell.
plasmolysis- is the separation of plant cell cytoplasm from the cell wall as a result of water loss.
cytolysis-the bursting or rupturing of cell membrane when the cell can no longer contain the excessive inflow of water (or extracellular fluid).

The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is called?
The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is plasmolysis
What does plasmolysis explain?
Plasmolysis explains the process in plant cells where the cell membrane detaches from the cell wall due to water loss, leading to the shrinking of the cell contents. This occurs when a plant cell is placed in a hypertonic solution, causing water to move out of the cell.
What do you call it when a plant cell is placed in a hypertonic solution?
yes...when placed in a hypertonic solution, it goes shrinks (plasmolysis).
Which prokaryotes should be expected to be most strongly resistant to plasmolysis in hypertonic enviornments?
Halophiles, which are prokaryotes that thrive in high salt environments, are expected to be most strongly resistant to plasmolysis in hypertonic environments. Their ability to maintain high internal salt concentrations allows them to counteract the water loss and maintain turgor pressure, preventing plasmolysis.
What are the effects of hypertonic solutions on living cells?
Hypertonic solutions are solutions that have a higher concentration than that of its immediate environment. The effects of hypertonic solutions on living cells is crenation in animal cells and plasmolysis in plant cells.
What is the contraction or shrinking of the cell membrane of a plant cell in a hypertonic solution in response to the loss of water by osmosis?
plasmolysis
What is the shrinking of cytoplasm by osmosis called?
The shrinking of cytoplasm by osmosis is called plasmolysis. This occurs when a plant cell loses water due to a hypertonic environment, causing the cell membrane to detach from the cell wall.
What causes plasmolysis in plants?
Plasmolysis occurs when the cell(hypotonic) is kept in a hypertonic solution. If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure, making the plant cell flaccid. Plants with cells in this condition wilt. Further water loss causes plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane. Eventually cytorrhysis -- the complete collapse of the cell wall -- can occur.
Why can't plasmolysıs take place in an animal cell?
Plasmolysis cannot occur in animal cells because they lack a rigid cell wall, which is essential for this process. Plasmolysis involves the contraction of the cell membrane away from the cell wall due to loss of water in a hypertonic environment. In animal cells, instead of plasmolysis, the cell would shrink and potentially undergo crenation when placed in a hypertonic solution, as there is no cell wall to provide structural support.
Plasmolysis of a human red blood cell would occur if the cell were?
Placed in a hypertonic solution with a higher solute concentration than inside the cell, causing water to leave the cell and the cell to shrink and shrivel.
How can can plasmolysis be demonstrated in the laboratory using a filament of spirogyra?
To demonstrate plasmolysis with a filament of spirogyra in the laboratory, place the filament in a hypertonic solution such as salt water. As water leaves the cell by osmosis, the cytoplasm shrinks away from the cell wall, leading to the detachment of the cytoplasm from the cell wall, demonstrating plasmolysis. This can be observed under a microscope.
What is the difference between lysis and plasmolysis?
When a cell is placed in a hypotonic solution, water will enter the cell. This is called lysis. When a cell is placed in a hypertonic solution, water will leave the cell (causing it to shrink). This is called plasmolysis.
