What are the Conditions for Osmosis?

By BYJU'S Exam Prep

Updated on: November 9th, 2023

The Conditions for Osmosis are that the two solutions should have different concentrations, and the membrane separating the solutions should be semi-permeable. Molecules move through osmosis from a region of higher concentration to a region of lower concentration until the concentrations are equal on both sides of the membrane.

Significance and Types of Osmosis

Osmosis is a passive process that happens without spending any energy. Any solvent, including supercritical liquids and gases, can undergo the process of Osmosis.

Osmosis is of two types – Endosmosis and Exosmosis.

  • Endosmosis: If a substance is placed in a hypotonic solution, the solvent moves inside the cell, which becomes turgid and undergoes deplasmolysis. It is known as endosmosis.
  • Exosmosis: If a substance is placed in a hypertonic solution, the solvent moves outside the cell, which becomes flaccid and undergoes plasmolysis. It is known as exosmosis.

Conditions for Osmosis

The release of metabolic waste products and the transport of nutrients are influenced by osmosis. It is responsible for the water absorption from the soil and conducts it to the upper parts through the xylem.

  • By keeping the levels of intercellular fluid and water in balance, an organism’s internal environment is kept stable.
  • It keeps the cells turgid.
  • Apart from water loss due to transpiration, it is a process by which plants maintain their water content.
  • It regulates water diffusion between cells.
  • It causes the cell turgor that controls the movement of the plant and its constituent parts.
  • It regulates how sporangia and fruits dehisce.


What are the Conditions for Osmosis?

The two solutions must have different concentrations, and the membrane separating them must be semi-permeable are the Conditions to occur Osmosis. High osmotic pressure shields plants from the effects of drought.
