Plasmolysis is when a plant cell looses so much water (via osmosis) so the cell membrane begins to "peel away" from the cell wall :)

The prefix cyto- comes from a word meaning .?
a prefix meaning 'cell' as in cytoplasm. The origin is Greek 'Cutos' meaning a vessel or container
What is the meaning of bartolina?
dark cell, dungeon
What does the prefix cyto comes from a word meaning?
cell
What is the English meaning of Malayalam word nilavara?
Nilavara = underground cell of house
What is the definition of uncellular?
Unicellular, as in a unicellular organism, means "To have on cell". The prefix "Uni-" meaning one or single, and the root word is cellular or cell.
What would a blood cell do if it went into a salt solution?
It will get plasmolysed.
Do cells reccover from the state of plasmolysis?
Yes, if a plasmolysed cell is placed in a hypotonic solution it can recover as a turgid cell.
What does a plant cell look like when it is plasmolysed?
externally the cell looks the same as the cell wall is rigid, internally the cell membrane pulls away from the cell wall
What is a plasmolysed cell?
A plasmolysed cell is where the cell membrane has pulled away from the cell wall, resulting in the collapse of the cell. This usually occurs because the cell has been placed in a solution with a concentration of water lower then that inside the cell so the water has diffused through the semi-permeable membrane of the cell into the solution and the cell shrivels because it has no water.
Which pressure is absent in plasmolysed cell?
Tugor pressure. Tugor pressure is caused by the cell's vacuole filling up with water and pressing against the outside of the cell. Isnt turgor pressure occurring in a turgid cell? =/
Why is the cell membrane still attached to the cell wall at some point when the cell is plasmolysed?
Cellulose microfibrils extending from strands of the Hechtian reticulum and entwining into the cell wall matrix act as anchors for the plasma membrane as it moves away from the wall during plasmolysis.
Do animal cells prefer hypertonic or hypotonic solutions?
isotonic solution is when the cell content has the same solute potential as the solution the cell is in. therefore no net movement of molecules.when a animal cell is placed in a hypotonic solution (a solution containing less solute particles than inside cell e.g water) molecules move from a high water potential to a low one because diffusion. net movement is into the cell. because of this the cell swells and eventually burst. this is osmotic shock.in a hypertonic solution the net movement is out of the cell. the cell shrinks this is called crenation.plant cell have a cell wall so in a hypotonic solution the cell swells but doesn't not burst because of the strong structure of the cellulose cell wall.the cell becomes turgid.in a hypertonic solution the net movement is out of the cell because of the high solute conc outside the cell. the cell membrane begins to pull away from the cell wall. the cell is plasmolysed. when fully plasmolysed it is irreversible.
What will happen if Plasmolysed Spirogyra filament is placed in water?

What does prolonged plasmolysis do to cells?
Plasmolysis might be a disadvantage to a cell when too much water is drawn out of the cell. This could cause the cell to collapse. This rarely happens in nature but can be seen in laboratory testing when the cell is forced into a concentrated saline solution.
What fills the space between cell wall and membrane after plasmolysis?
The cell membrane is a selectively permeable membrane that will only let water and solutes across it. The cell membrane freely allows pretty much everything to pass across it, meaning that things unable to pass the membrane back up and push it away from the cell wall. Therefore the gap is filled with the SUGAR SOLUTION that is surrounding the cell.
What happens to a animal cell when in a hypertonic solution?
1. When a plant cell is immersed in a solution with low water potential, the water potential of its cell sap is higher than that of the solution outside its cell.2. water will leave the cell by osmosis. As the cell loses water the vacuole decreases in size and the cytoplasm shrinks away from the cell wall.3. the shrinkage of cytoplasm and cell membrane away from the cell wall is known as plasmolyses or dehydrated cell. the cell is said to be plasmolysed. A plasmolysed cell can be restored to its original state by placing it in water or in a solution with high water potential.
What is the medical term meaning granular cell?
Granulocyte is the medical term meaning granular cell.
