Osmosis

Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration, aiming to equalize solute concentrations on both sides of the membrane. This process occurs without the expenditure of energy.

Overview

Osmosis is a vital biological process that involves the movement of water across semi-permeable membranes. This process is essential for maintaining cell structure, nutrient absorption, and waste removal in both plant and animal cells. Understanding osmosis helps explain how cells interact with thei...

Key Terms

Osmosis
The movement of water across a semi-permeable membrane.

Example: Water moving into a plant root.

Semi-permeable membrane
A barrier that allows certain substances to pass while blocking others.

Example: Cell membranes are semi-permeable.

Solute

Turgor pressure
The pressure exerted by water inside the cell against the cell wall.

Example: Turgor pressure keeps plants upright.

Hypertonic solution
