Question

What is the relationship between osmosis and turgor pressure?

Answer 1

Hint: Osmosis can be demonstrated by adding potato slices to a high salinity solution. The water moves out from the potato cells and the cell loses turgor pressure and shrinks.

Complete answer:
Osmosis is the movement of solvent molecules from an area of higher concentration to an area of lower concentration through a semipermeable membrane.
Osmotic pressure is the minimum external pressure required to inhibit the movement of solvent molecules across a membrane, resulting in no net movement of solvent molecules. Osmotic pressure depends on the molar concentration of the solution.
Osmosis is a fundamental process in biological systems, as most biological membranes are semipermeable. Biological membranes are impermeable to molecules of large sizes but are permeable to small sized molecules.
Turgor pressure is the pressure exerted by the contents of a cell onto its plasma membrane which pushes it against the cell wall. Turgor pressure is generated by the osmotic flow of water and other solvents through biological membranes like cell membranes. Turgidity is the pressure exerted by the osmotic flow of solvents. The cell contents push up against the cell wall when turgor pressure is too high. Low turgor pressure results in flaccidity of the cell.

Note:
Osmosis is the primary method of water regulation in biological systems like cells.
Wilting in plants occurs due to a lack in turgor pressure.
Turgor pressure plays an important role in the facilitation of nutrient transport in plants. Turgor pressure can differ in different parts of an organism.
