    INTRODUCTION: This lab was done to know how diffusion takes place. In the first place‚ particular penetrability is characterize as the particular "determination" with reference to what particles to enter the cell or kept outside of the cell; it is basically specific of what is going in and what is going out‚ primarily supplements going in and squanders going out (Marieb). Moreover‚ specific penetrability happens in two ways: dynamic process that requires ATP for the transportation of cell while
