A&P Lab Diffusion/osmosis

Motion energy or energy that can do work

When the concentration of a substance differs from 1 point to another

The term used to the visible movement of large particles being hit by invisibly small molecules. The movement of the visible particles is evidence of the kinetic energy of the molecules.

The sum of the atomic weights of all the atoms in a molecule.

Tendency for solute molecules to move from an area of high concentration to an area of low concentration

Determines how quicklly a cell can acquire nutrients or rid itself of waste, how quickly it diffuses

Only allows something to pass

Diffusion of water thru a membrane from a less concentrated solution to a more concentrated solution.

Solution that causes cells to shrink.

Shrink or shrivel

Solution that causes cells to swell

Movement, due to a pressure difference of a liquid thru a filter that prevents some or all of the substances in the liquid from passing thru.

Does not require ATP

Carrier mediated process that requires ATP and can move substances against a concentration gradient.
