Question

Differentiate between the following:

Osmotic pressure and Turgor pressure.

Answer 1

1. The minimum pressure that must be given to a solution to prevent the inward flow of its pure solvent through a semipermeable membrane is known as osmotic pressure.
2. The pressure inside the cell that pushes the plasma membrane against the plant cell wall is referred to as turgor pressure.

Turgor pressure	Osmotic pressure
The pressure (hydrostatic) that occurs in the cell as a result of osmotic water entry.	It's the pressure that builds up in a solution when it's separated from water by a semipermeable membrane.
2. Turgor pressure keeps plant parts in their original form and size. The maximum turgor pressure is found in a completely turgid cell.	2. The osmotic pressure is measured in bars and is equal to a positive osmotic potential.
