Question

Movement of solvent into the cell, through a semipermeable membrane is known as

Answer 1

Hint The biggest hint in the question is given in the word that is a semi-permeable membrane, as there is the movement of the solvent inside the cell, and the presence of a semi-permeable membrane directly indicates towards the most common process of osmosis.

Complete answer:
The answer to this question is osmosis, as osmosis is a type of process in which the solvent molecules pass through the semipermeable membrane from the less concentrated solution to the more concentrated solution. The main result of the process of osmosis is the equalization of the solute concentration on both sides.

The external pressure which is needed to be applied so that there will be no net movement of the solvent across the semipermeable membrane is called osmotic pressure.

Whenever any type of the cell is placed in the water, the movement of the water depends upon the solute concentration basically, as the water tends to move from low solute concentration to the higher solute concentration.

For example, whenever the cell is placed in the saltwater, the water molecules tend to move outwards from the cell, whereas when the cell is placed in the freshwater, molecules of the water tend to move inside the cell.

Note:
- Whenever there is the movement of the solvent from low concentration to higher concentration and there is the presence of a semi-permeable membrane between the movements, the process is always the osmosis.
- The whole movement of the osmosis is the spontaneous process. Osmosis plays a very important role in biological systems. The semi-permeable membrane mostly does not permit the movement of polar molecules and larger molecules like ions, proteins, etc.
