WebThe most important thing about membranes is that they regulate what moves in and out of a cell. The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. WebTransverse Diffusion Over a Semipermeable Membrane Purpose: Examine the passage of materials through a semipermeable membrane. Question: Does molecule size have an impact on diffusion? Hypothesis: If molecules are tiny enough, they can pass through the pores in a semi-permeable membrane and diffuse over it. Variables: Independent: …
