Water, Carbon dioxide and Oxygen travel in and out of semipermeable barrier with the help of diffusion.

Factors regulating rate of diffusion are as follows;

1.Concentration gradient

2.Temperature

3.Surface area

The movement of molecules from an area of higher concentration to an area of lower concentration is known as diffusion.

Water follows osmosis to move in and out of cell. Osmosis is a type of diffusion.

Concentration Gradient:

The difference in concentration and the rate of diffusion are directly related to each other.

Temperature:

The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the rate of diffusion increases.

Surface area:

The greater the surface area, the faster the rate of diffusion.
