ADVERTISEMENTS: The below mentioned article provides a study note on the plasmolysis in plant cell. In many plant cells, the protoplasm may shrink completely away from the cell wall and collect as a spherical mass in the centre or in one corner of the cell (Fig. 665). This phenomenon is called plasmolysis. When this contraction […]

The process of plasmolysis in plant cell is defined as: (a) Breakdown of plasma membrane in hypotonic solution. (b) Shrinkage of cytoplasm in hypertonic medium. (c) Shrinkage of Nucleoplasm.

Exosmosis: Exosmosis is defined as the osmotic withdrawal of water from a cell or system when it is placed in a hypertonic solution. Exosmosis in a plant cell leads to plasmolysis. 2. Plasmolysis (Plasma = cytoplasm; lysis = breakdown) When a plant cell is kept in a hypertonic solution, water leaves the cell due to exosmosis.

If exosmosis continues in a plant cell, the cytoplasm appears to be shrunken. This is called plasmolysis and the cell Is said to be plasmolysed. Plasmolysis is the loss of water from the cytoplasm of a plant cell when placed in a hypertonic solution. Here, the water potential of the cytoplasm is higher than the water potential of the outside solution.

Question 44. This phenomenon of water loss from cells which is akin to exosmosis is called plasmolysis. Wilting of plants noticed under conditions of water scarcity is an indication of plasmolysis of cells.

Plasmolysis in a plant cell is defined as GB Cells Tissues Plasmolysis in a plant cell is defined as. break down (lysis) of plasma membrane in hypotonic medium; shrinkage of cytoplasm in hypertonic medium; shrinkage of nucleoplasm; none of them; Answer. When a cell is immersed in hypertonic (very concentrated) solution, water diffuses out of the cell by the process of osmosis.

The Plasmolysis is defined as the process of shrinkage of the cytoplasm of a plant cell occurred due to loss of water in the plant cell. Share Save Report.

(b) Shrinkage of cytoplasm in hypertonic medium. As a result of this the cell shrinks. This process is called exosmosis. If exosmosis continues in a plant cell, the cytoplasm appears to be shrunken. This is called plasmolysis and the cell Is said to be plasmolysed.

It occurs when plant cells are placed in a solution that has a higher concentration of solutes than the cell does. In this, plant cell is kept in hypertonic solution. Plasmolysis Definition Plasmolysis is when plant cells lose water after being placed in a solution that has a higher concentration of solutes than the cell does.

Shrinkage of cytoplasm in hypertonic medium. Plasmolysis in a plant cell is defined as the process of shrinkage of the cytoplasm as a result of loss of water from the cell. It occurs when plant cells are placed in a solution that has a higher concentration of solutes than the cell does. Plasmolysis in a plant cell is defined as (a) break down (lysis) of plasma membrane in hypotonic ) shrinkage of nucleoplasm (d) None of the above Answer. When a cell is kept in hypertonic solution then exosmosis occurs, i.e., water molecules move outward from lower solute concentration to higher solute concentration through cell membrane. Due to this, the cell protoplasm shrinks. Exosomosis is also termed as plasmolysis.
