Ap biology lab 1 - diffusion & osmosis paul andersen starts with a brief description of diffusion and osmosis he then describes the diffusion demonstration and how molecules move over time. Ap biology lab #1: diffusion and osmosis purpose: in this lab, we will be conducting an experiment where we will observe the acts of passive transport: diffusion and osmosis the experiment will show how molecules in a solution are able to move from an area of high concentration to an area of low concentration.

First, slice the potato into to 3-cm discs use the potato corer to core out 24 cores weigh 4 cores together and record their mass fill each cup with one of the following solutions: distilled water, 02 m glucose, 04 m glucose, 06 m glucose, 08 glucose, and 10 m glucose in each cup put 4 potato cores, and allow them to sit over night.
