Lesson 10: Membrane Transport

One of the main ways the substance can get into and out of cells by simple diffusion. Diffusion movement of molecules from a region of high concentration in the region of low concentration by random molecular motion (www.biologyplace.com).

Diffusion in the solution can be accelerated by heating the solution. This makes sense, given that heat is the total amount of kinetic energy in the solution. Similarly, to slow down the diffusion of the solution can be cooled. Be careful not to be confused with a diffusion convection currents caused by uneven heating of solutions or the ...
