An analogy Passive transport

An analogy passive transport is the comparing riding to the bicycle and to hill the passive transport.

Explanation:

Passive transport is also called to the passive diffusion is to the process passes the molecule through a cell to an low area of concentration.

Passive transport gives to the molecule room to breathe and the term is remembered its the opposite transport active.Passive transport is there are four types in a biology:- (1) facilitated diffusion (2) simple diffusion (3) osmosis (4) filtration.Passive transport is the reason to that ethanol molecule to the simple diffusion with expert ease,and pass to the consuming energy.Passive transport is to the communicate is easy to miss the fact of neurons and cells,its contains concentration on the outside system.Passive transport is that contain the vitamin and minerals tend to the extract bodies using the separate liquid.Passive transport are that perform another instance of this time and simple movement to the concentration gradient.Facilitated diffusion :- is that process to perform the molecule or pass the cell membrane.Simple diffusion :- is that process without the aid of internal protein membrane.Osmosis :- is the process of concentrations of material on side of membrane.Filtration :-this process is to remove of solid materials into the body.
