Movement in cells

Movement in the cells involve physiological process

There two methods of physiological process: 

1.passive transport

2.active transport

Passive transport involve transport of substance in and out the cell without energy use

Active transport involve transport of substance using energy Passive transport involve two prosess Diffusion and osmosis . Diffusion is the movement of substance from an area of high concentration to an area of low concentration while osmosis is the movement of water molecules from an area of low concentration to an area of high concentration . Diffusion is of two types simple Diffusion and facilitated Diffusion. Simple Diffusion involve the simple movement while in facilitated Diffusion carriers are required
