Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However‚ Active transport requires ATPs which have energy in order for it to move something through the cell membrane. There are different types of transport to suit the sizes of molecules as well. Passive transport includes diffusion‚ osmosis‚ and
