Plasmolysis refers to the contraction of the protoplast of a plant cell as a result of loss of water from the cell. The plasma membrane moves away from the cell wall due to loss of water through osmosis. Osmosis on its part, is the movement of water molecules from a region of high water potential to a region of lower water potential through selectively permeable membrane.

Can animal cells undergo plasmolysis?
Animal cells undergo lysis, and plant cells undergo plasmolysis. Lysis occurs when a plant cell explodes due to too much pressure on the inside, and plasmolysis occurs when the vacuole of a plant cell shrinks away from the cell wall due to lack of water.
Why are plant cells selected to demonstrate plasmolysis rather than animal cells?
Plant cells are selected to demonstrate plasmolysis because they have a cell wall that maintains the structure of the cell even when the cell membrane shrinks due to water loss. Animal cells do not have a cell wall, so they would burst instead of undergoing plasmolysis in a hypertonic solution.
What will happen if put plant cell in salty water?
Salt draws water from plant cells. This causes the cells to dehydrate and the plant to shrivel up and die.
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.
Why does plasmolysis occur only in plant cells?
Plasmolysis occurs only in plant cells due to their rigid cell walls, which provide structural support and maintain cell shape. When plant cells are placed in a hypertonic solution, water exits the cell, causing the cytoplasm to shrink away from the cell wall. This process highlights the difference between plant and animal cells; animal cells lack a cell wall, so they would simply undergo cytolysis or shrinkage without the structural context provided by a rigid wall. Thus, plasmolysis is a phenomenon specifically associated with the unique characteristics of plant cell structure.

What are some practical applications of plasmolysis in animal cells?
i don't know plss help me because i need it to may lab activity the submission is tomorrow...:(
What is the shrinking of plant cells called when water leaves so the cell membrane pulls away from the cell wall?
plasmolysis
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 term describes the condition of plant cells after being placed in distilled water?
Plasmolysis describes the condition of plant cells after being placed in distilled water. In plasmolysis, water exits the cell by osmosis, causing the cell membrane to detach from the cell wall. This results in the cell shrinking and the cytoplasm pulling away from the cell wall.
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 shrinking of plant cells when water leaves the cell membrane?
It is called plasmolysis. The cytoplasm and vacuole shrink but cell wall remains the same.
Suppose the test tube contained plant cells instead of red blood cells what will happened if the cells were placed in water with very little salt?
If the plant cells were placed in water with very little salt, they would undergo a process known as plasmolysis. Plasmolysis is the shrinking of the cell membrane away from the cell wall due to water loss. This occurs because the water concentration outside the cells is higher than inside, causing water to move out of the cells, leading to wilting and potential cell damage.
