Potato Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you

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

Cell Membrane Permeability and Osmosis Experiment 3 Objectives: To demonstrate the mechanism involved in Osmosis; To demonstrate the tonicity of solutions by subjecting the cells to different concentration of solute. To view‚ under the microscope‚ any change in the shape and volume of the cells after subjecting them to different concentrations of solutes; To demonstrate the permeability of cell membrane by subjecting the cells to different solutes; To demonstrate the mechanism involved in

and Isotonic Solutions Affect the Water Movement of a Cell? Purpose: The purpose of this activity is to teach students about osmosis and the effects of hypotonic‚ hypertonic‚ and isotonic solutions on animal cells. This lab is designed for high school biology students but may be adapted for middle school students. Objectives: The students will be able to describe osmosis and differentiate between the effects of hypotonic‚ hypertonic‚ and isotonic solutions on animal cells and determine the equilibrium

Introduction: 1. The purpose of doing this lab was to recognize the effects that salt‚ in different strengths‚ has on cells. 2. Osmosis is the movement of water molecules

occurs when solutes are transferred from a high concentration of that solute to a lower concentration of solutes. Solutes do not depend on the concentration of other solutes‚ which allows the cell to take in oxygen while releasing carbon dioxide. Osmosis is a special type of diffusion‚ which occurs when water is diffused across the membrane. This can be affected by how hydrophilic a solute is on either side of the membrane. The diffusion of glucose‚ starch‚ and iodine was observed when the solutes

Osmosis in Plants Outline: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Definition - Osmosis: Movement of a solvent (liquid) through a semi-permeable membrane separating solutions of different concentrations. The solvent passes from a less concentrated solution to a more concentrated solution until the two concentrations are equal. All

INTRODUCTION Osmosis is a passive movement of water molecules going across the partially permeable membrane. It is a very spontaneous process due to the downhill energy flow known as “water potential” by which‚ water molecules move from a region of higher water potential
