Question

How diffusion helps animals and plants (6marks)

Answer 1

Diffusion is a passive process involving the movement of molecules from a region of a higher concentration to one of a lower concentration (the term passive means that the process does not require an input of energy to take place).

Answer 2

In both plants and animals, diffusion is important in the movement of important molecules both in and out of the cell. It is also essential for the removal of waste products produced by the cells themselves.
