Naturally, molecules move from an area of high concentration to low concentration without the need of energy. This type of movement is passive transport. Molecules with strong electrical charges such as ions cannot simply diffuse across the cell membrane. Irrespective of their size, their charge prevents them from moving freely across the cell membrane.
passive transport, the movement of small molecules across the membrane of a cell by diffusion.

Passive transport is essential to various processes of metabolism, such as the intake of digestive products by the cells lining the intestines.
