Compare and Contrast Diffusion, Osmosis, Active Transport, Passive

							Compare and Contrast: Diffusion, Osmosis, Active
Transport, Passive Transport, Endocytosis, Excytosis

     All of these terms are ways for molecules to get
across membranes. The method that works best
depends on the size of the molecule trying to get
across and the concentration of similar molecules on
either side of the membrane.
     Diffusion, Osmosis and passive transport are
similar because small molecules move from areas of
high concentration to areas of lower concentration.
Osmosis is only different because it refers to water
and passive transport is a little more different because
protein channels have to be open for molecules to get
across.
     Active transport, endocytosis and exocytosis are
similar because they all require energy so they don’t
rely on concentration to get molecules across the
membrane. They are different because active
transport gets small molecules through protein
channels and endo and exo cytosis get larger
molecules across by pinching off vesicles.
