The Effect Of Osmosis In Animal Cells, Plant Cells & A Model System

Introduction

The purpose of this experiment is to determine as well as observe the movement of water molecules going in and coming out of model system, animal cell and plant cell through a process called osmosis. Osmosis is referred to the movement of water molecules through a semi-permeable cell membrane from an area of low solute concentration to an area of high solute concentration within a biological cell system (Karp, 2010). In other terms osmosis can also be referred to as the movement of water molecules through a cell membrane from an area of high water concentration to an area of low water concentration (Karp, 2010). In this lab the membrane of the cells that are tested are permeable to water molecules, but impermeable to solutes. Permeability refers to substances that can enter, while impermeability means that substances can not enter (Karp, 2010). Within this experiment when the process of osmosis is observed between two solutions, the solute concentrations between the two solutions are compared in either three ways; they can either be isotonic, hypertonic or hypotonic. An isotonic solution is a solution that has
