Question

A protein cell attains turgidity due to
A. Electrolysis
B. Exosmosis
C. Plasmolysis
D. Hydrolysis
E. Endosmosis

Answer 1

Hint:
Cell is the basic of life in living organisms.
Cells are more often known as “Building blocks of life”.
Cells provide six functions such as
1. Structure and support,
2. Facilitate growth through mitosis,
3. Allow passive and active transport,
4. Produce energy, create metabolic reactions
5. Reproduction.

Complete answer:
To solve this question, we need to know about the various types of processes related to cells.
Cell is the smallest unit or the basic unit of living organisms.
Two types of cells are:
1. Plant cell
2. Animal cell
Electrolysis: It is the process by which electric current is passed through a substance for a chemical change.
Exosmosis: The passage of a fluid through a semipermeable membrane toward a solution of lower concentration through a cell membrane into the surrounding medium.
Endosmosis: It is the movement of the water inside the cells when the cell is placed in a hypotonic solution.
This movement of water causes the cell to swell.
Plasmolysis: It is a process in which when a cell is placed in a hypertonic solution so due to exosmosis the cell loses water and shrinks.
Hydrolysis: It is the chemical breakdown of a compound due to reaction with water.
If a cell is placed in a hypotonic medium, it will swell due to the uptake of water by endosmosis.
So, by this way the plant cell stains turgidity.

So, the correct option is option E. Endosmosis.

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.
