Simple diffusion short definition
WebbMethod: The rate of simple diffusion can be expressed by a modification of Fick's Law for small, nonpolar molecules. The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time.

Webb1 : movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane 2 : a process of absorption or diffusion (see diffusion sense 3a) suggestive of the flow of osmotic action orchid first choiceWebb30 nov. 2024 · Why does Diffusion take place. Diffusion : The spreading out and mixing of a substance with another substance due to the motion of its particles is called diffusion. Diffusion is a property of matter which is based on the motion of its particles. Diffusion is fastest in gases because the particles in gases move very rapidly. iq tricksWebb7 Simple (passive) diffusion The unique design of biological membranes provides a barrier separating a hospitable environment inside the membrane from the external environment.
