Diffusion is movement of a substance from a region of higer concentrations to the region of lower concentrations.

Diffusion is movement of a substance from a region of higer concen

Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). The passive forms of transport, diffusion and osmosis, move materials of small molecular weight across membranes.

it is nothing but a osmosis means the liquid enter from higher to lower concentrations or lower to higher concentrations

definition of plasma membrane is movement of a substance from a region of higher concentration to the region of lower concentration is called plasma membrane

SimpleDiffusion acrosstheCell(Plasma)Membrane. The structure of the lipid bilayer allows small, unchargedsubstancessuch as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to passthroughthecell membrane, down their concentration gradient, by simplediffusion.

All cells are surrounded by aplasma membrane. Themembraneis composed of a phospholipid bilayer arranged back-to-back. Themembraneis also coveredinplaces with cholesterol molecules and proteins. Theplasma membraneis selectively permeable and regulates which molecules are allowed to enter and exit thecell.

diffusion is the movement of substances from high concentration to low concentration.

Theplasma membrane, also called thecell membrane, is themembranefound in all cells that separates the interior of thecellfrom the outside environment. In bacterial and plant cells, acellwall is attached to theplasma membraneon its outside surface.

water from osmosis and depend upon a material which transferred

Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.
