What is diffusion?
Diffusion is the process where molecules move from a higher concentrated area to a lower concentrated area.
When will this process stop?
It stops when all the molecules are evenly distributed.
Do molecules even stop moving?
No they do not, they always move.
What are the factors that determine the rate of diffusion?
It is affected by temperature, size of molecules and the steepness of the concentrated gradient.
Can you name some examples of diffusion in a living organism?
Gaseous exchange between the lungs and the surroundings.
Mineral salts enter the root cell when the root cell takes in water from the soil.
