Hint: Only some molecules can flow across a semipermeable membrane, which prevents the passage of other molecules. It means a semipermeable barrier acts as a filter. Different types of semipermeable membranes can block out molecules of different sizes.
Complete Step by Step Answer:
Solvent molecules passing through the semipermeable membrane is called osmosis. The minimum pressure which is required to be applied to the solution to prevent the inward flow of the solvent across a semipermeable membrane is known as osmotic pressure. This process is known as osmosis. Osmotic pressure is a colligative property.
The direction of flow of solvent is from that side of the semipermeable membrane where the concentration of solute is low to the other side where the concentration of solute is high. The factors on which osmotic pressure depends are the temperature and the concentration of solute. If there is no osmotic pressure, there will be no movement of solvent. Osmosis is a unidirectional process. It tends to make the concentration of solute across the two sides of the membrane equal.
Correct Option: (D) Osmosis.
Note: Electrolysis is the process of changing a substance's chemical composition by passing an electric current through it. A separation technique known as electrophoresis depends on the movement of charged species in a supporting medium when they are subjected to an electric field. Cataphoresis is another name for electrophoresis.
