endosmosis

The scientist observes endosmosis in a glass tube.

Definition

1. Noun:
   • Inward flow of a fluid: "endosmosis" refers to the passage of a fluid from an area of lower concentration to an area of higher concentration through a semipermeable membrane, specifically the movement into a cell or vessel. It is the opposite of exosmosis.
   • Scientific process: In biology and chemistry, "endosmosis" describes the osmotic movement of a solvent (usually water) into a system, such as a cell or a tube, due to differences in solute concentration.

Usage Examples

• Noun:
  • The endosmosis of water into the plant roots is essential for nutrient uptake. (The inward movement of water through the root membrane.)
  • Scientists observed endosmosis when the sugar solution caused water to enter the dialysis bag. (The inward flow of water across the membrane.)

Advanced Usage

• "to undergo endosmosis": to experience the inward osmotic flow.

  • The red blood cells undergo endosmosis when placed in a hypotonic solution. (The cells take in water from the surrounding fluid.)

• "rate of endosmosis": the speed at which the inward osmotic movement occurs.

  • The rate of endosmosis depends on the temperature and the concentration gradient. (The speed of inward flow varies with conditions.)

Variants and Related Words

• Endosmotic (adj): relating to or characterized by endosmosis.

  • The endosmotic pressure caused the cell to swell. (The pressure from inward osmotic flow.)

• Endosmometer (n): an instrument used to measure endosmosis.

  • The researcher used an endosmometer to quantify the water uptake. (A device for measuring inward osmotic movement.)

Synonyms

• Inward osmosis: the specific type of osmosis moving into a system.
• Intake through membrane: the process of a substance being drawn into a structure via a semipermeable barrier.
