Question

The movement of solvent molecules into the region of higher solute concentration through a semipermeable membrane is called
A. imbibition
B. diffusion
C. osmosis
D. plasmolysis

Answer 1

Hint: Osmosis is defined as the process in which the solvent or water moves from a region of higher concentration to a region of lower concentration through a semipermeable membrane. This process tends to equalize the solute concentrations on the two sides. This process by osmotic pressure. It is important for living organisms because it allows water and nutrients dissolved in water to pass through cell membranes.

Complete answer:
> Option A is imbibition
Imbibition is a special type of diffusion. It takes place when water is adsorbed by solids-colloids that causes an increase in volume. Examples- the absorption of water by seeds and dry wood.

> Option B is diffusion
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases as their particles move randomly from place to place. Diffusion is an important process for living things because it is how substances move in and out of cells.

> Option c is osmosis
In the process of Osmosis, water or solvent move across a semipermeable membrane toward a higher concentration of solvent from a lower concentration of solvent. The solvent is usually water, but can also be other liquids, supercritical liquids, and even gases.

> Option D is Plasmolysis
In the process of Plasmolysis, cells lose water in a hypertonic solution. The reverse process of plasmolisis is deplasmolysis or cytolysis. This can occur if the cell is in a hypotonic solution.

Hence, the correct answer is option (C).

Note: Semipermeable membrane is a type of biological or synthetic, polymeric membrane. It allows only certain molecules or ions to pass through it by diffusion. Or sometimes by more specialized processes like facilitated diffusion, passive transport, or active transport.
