Web1. Description of Diffusion and Osmosis. A water solution that contains nutrients, wastes, gases, salts and other substances surrounds cells. This is the external environment of a cell. The cell’s outer surface of the plasma membrane is in contact with this external environment, while the inner surface is in contact with the cytoplasm.

Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of … See more Diffusion is of fundamental importance in many disciplines of physics, chemistry, and biology. Some example applications of diffusion: • Sintering to produce solid materials (powder metallurgy, … See more Fundamentally, two types of diffusion are distinguished: • Tracer diffusion and Self-diffusion, which is a spontaneous mixing of molecules taking place in the … See more Collective diffusion is the diffusion of a large number of particles, most often within a solvent. Contrary to brownian motion, which is the diffusion of a single particle, interactions between particles may have to be considered, unless … See more • Diffusion – Transport of dissolved species from the highest to the lowest concentration region • Ambipolar diffusion See more Diffusion is part of the transport phenomena. Of mass transport mechanisms, molecular diffusion is known as a slower one.

WebHere, the cell can't import glucose for free using diffusion, because the natural tendency of the glucose will be to diffuse out rather than flowing in.Instead, the cell must bring in more glucose molecules via active …

WebDiffusion rate is directly proportional to the gradient but also depends on the molecule’s lipid solubility, size, degree of ionization, and the area of absorptive surface. Because the cell membrane is lipoid, lipid-soluble drugs diffuse most rapidly. Small molecules tend to penetrate membranes more rapidly than larger ones.
