Question

What is meant by deplasmolysis?
A. Process of returning a plasmolysed cell to its initial stage.
B. Process of returning a plasmolysed cell to a more plasmolysed stage.
C. Process of returning a normal cell to its plasmolysed stage.
D. Process of returning a normal cell to its shrink form.

Answer 1

Hint: Plasmolysis is the process in which cells lose water in a hypertonic solution.
So the turgor pressure decreases to that level where the protoplasm of the cell peel off from the cell wall and leaves the gaps between the cell wall and the membrane.
This gap makes the plant cell shrink.
A continued decrease in pressure leads to complete collapse of the cell wall.

Complete answer:
 In order to solve this question we need to learn more cells and we need to learn about what is deplasmolysis.
Cell is the smallest unit or the basic unit of living organisms.
Two types of cells are:
1. Plant cell
2. Animal cell
Plant cell is the type of cell present in plants.
Plants cells consist of following contents:
1. Outer coverings
A. Cell wall
B. Cell membrane
2. Nucleus
3. Cytoplasm
4. Protoplasmic Components
A. Golgi bodies
B. Mitochondria
C. Chloroplast
D. A single large vacuole
E. Endoplasmic reticulum
F. Peroxisome
G. Ribosome
Animal cells are the type of cells found in animals.
Animal cells consist of following components:
1. Outer covering
A. Cell membrane
2. Nucleus
3. Cytoplasm
4. Protoplasm components
A. Mitochondria
B. Many small vacuoles
C. Endoplasmic reticulum
D. Golgi bodies
E. Centromere
F. Lysosome
Plasmolysis is a process in which when a cell is placed in a hypertonic solution, then due to exosmosis, the cell loses water and shrinks.
Deplasmolysis: It means when the cell is placed in water or in the hypotonic solution, then the water molecules enter inside the cell and protoplasm of the cell returns to its initial state with normal turgor..

So, the correct option is option A. process of returning a plasmolysed cell into its initial stage.

Note: Tonicity: It is the relative concentration of solutes with respect to solution which determine the direction and extent of diffusion.
Hypertonic solution: A solution that contains more dissolved solute such as salt and other electrolytes than is found in normal cells and blood.
For example: soaking wounds.
Hypotonic solution: A solution that has a lower osmotic pressure than another solution.
It also refers to a solution that has less solute and more water than another solution.
