What are three types of passive transport?

Answer 1

1. Diffusion- is the movement of the substance from an area of higher concentration to an area of lower concentration,
2. Osmosis- is the diffusion of water molecule only through a membrane semipermeable cell membranes allow water to pass through them until equilibrium occurs.
   
3. Facilitated Diffusion- carrier proteins, and channel proteins it occurs when molecule pass through a cells membrane.

Answer 2

Three types of passive transport include simple diffusion, facilitated diffusion, and osmosis. Simple diffusion is the movement of molecules across the cell membrane from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to help large or charged molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
