Which is best the definition of he term diffusion?
|
|
the movement of water across a cell membrane
|
|
|
the movement of water from root cells to leaf cells
|
|
|
the movement of particles from an area of high concentration to an area of lower concentration
|
|
|
the movement of particles from an area of a low concentration to an area of a higher concentration
|
Explanation:
Detailed explanation-1: -Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy.
Detailed explanation-2: -diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
Detailed explanation-3: -In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
