Question

What is the principle of diffusion?

Answer 1

Diffusion:

The movement of ions and molecules from a region of high concentration to a region of low concentration is called diffusion.

Principle of diffusion:

1. The diffusion is based on the principle that the net flow of molecules occurs from regions of higher concentration to regions of low concern under the influence of concentration gradient.
2. In biological systems it is a type of passive transport in which the cell transports the molecules and other essential substances across the concentration gradient without any energy requirement.
