This document summarizes an AP Biology lab review covering several topics: - Lab 1 discusses diffusion and osmosis, describing experiments with dialysis tubing and potato cores in sucrose solutions. It concludes that water moves based on concentration gradients and molecule size. - Lab 2 examines enzyme catalysis, measuring factors like pH and temperature that affect the rate of a reaction catalyzed by the enzyme catalase. - Lab 3 covers mitosis and meiosis, describing experiments with onion root tips and fungi to observe cell stages and genetic recombination.
