Passive transport is the movement of biochemicals and other atomic or molecular substances across cell membranes, without need of energy input.
Explanation:
Passive transport does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.
The rate of passive transport depends on the permeability of the cell membrane.
The four main kinds of passive transport are simple diffusion , facilitated diffusion,
filteration and osmosis.
