Match the following

• Osmosis

• Movement of molecules across a plasma membrane by means of Protein Channel.

• Diffusion

• Movement of molecules from High to Low. It moves without assistance through the membrane.

• Facilitated Diffusion

• Type of transport that does not require energy to move substances across cell membranes.
