Which statement describes how diffusion works?
molecules always move from inside of the cell to outside of the cell. molecules always move from areas of high concentration to low concentration. molecules always move from areas of low concentration to high concentration. molecules always move from of outside the cell to inside of the cell.

Answer : The correct option is, Molecules always move from areas of high concentration to low concentration.

Explanation :

Diffusion : It is a process in which the solute particles flow from a solution of high concentration to a solution of low concentration.

Or we can say that, the diffusion is the movement of a molecule or substance from the area of high concentration to the area of low concentration.

The example of diffusion is, when the perfume is sprayed in one corner of the room then it diffuses into the entire room and you can smell it everywhere.

Hence, the correct statement is, Molecules always move from areas of high concentration to low concentration.
