You should use diagrams were possible.
……………..Answer preview………………..
Diffusion is the process by which substances cross a permeable plasma membrane. The molecules move from an area of high concentration area to an of the low concentrated area. Molecules of any substance are always in motion they keep on moving, but if there is no energy is put into the system, the molecule will reach a state of equilibrium where they will be distributed equally throughout the system……..
