Microbiology Osmosis Lab Report Lab Experiment 9 Osmosis Introduction Kinetic energy is present in cells and its this energy that causes the cells to move. Diffusion causes cells to move from a higher concentration to a lower concentration. Osmosis is a diffusion that allows movement of water through a selectively permeable membrane. Osmosis occurs until it reaches equilibrium‚ or when the concentration on each side is the same. This is called an isotonic solution. A solution with differing

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

Introduction The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in

Pigmentation of an Onion Cell within 40% Ethanol and Deionized Water Purpose: To measure the amount of pigment in a solution of 40% ethanol and deionized water both containing pieces of an onion with a spectrometer. Hypothesis: 40% ethanol breaks down the cell creating less surface area and spreading out the pigment while the deionized water absorbs the pigment in a greater surface area. Procedure: Add 10ml of deionized water and 40% ethanol to a 6-dram vial Add 6g of chopped onion to the vials; allow
