Movement of material in and out of cells
It moves molecules from a low concentration to a high concentration, against the concentration gradient.
The taking in of matter by a living cell by invagination of its membrane to form a vacuole.
Diffusion is the net movement of molecules or atoms from a region of high concentration to a region of low concentration as a result of random motion of the molecules or atoms
Several factors affect the rate of diffusion of a solute including the mass of the solute, the temperature of the environment, the solvent density, and the distance traveled.
You can smell perfume because it diffuses into the air and makes its way into your nose.
A teabag placed in a cup of hot water will diffuse into the water.
Placing food coloring in a liquid will diffuse the color.
Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.
A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
Factors influencing affecting exchange of materials across membranes
