What is the difference between diffusion and active transport?

Open in App

Solution

Diffusion:
The movement of any substance from a region of its higher concentration to a region of lower concentration is referred to as diffusion.
Active transport:
Active transport is associated with accumulating high concentrations of molecules that the cell needs, such as glucose, ions, and amino acids.
Diffusion Active transport
Diffusion is a process in which substances move in and out of cells.
It is the movement of a substance by using the energy against a gradient in concentration across a plasma membrane
2. Diffusion does not require energy.
2. Active transport requires the expenditure of energy in the form of ATP.
3. Example: the smell of perfume.
3. Example: uptake of minerals from soil by the roots.
