Detailed explanation-1: -In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

Detailed explanation-2: -In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.

Detailed explanation-3: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

Detailed explanation-4: -Passive Diffusion The net flow of molecules is always down their concentration gradient-from a compartment with a high concentration to one with a lower concentration of the molecule.

Detailed explanation-5: -Passive diffusion follows a concentration gradient, which relates to the transport of molecules from a location of higher concentration to a site of lower concentration without using chemical energy according to Fick’s law of diffusion.
