My group and I are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house. Osmosis is a vital mechanism in the transport of fluids in living organisms. This point is clearly proven when you put a plant cell in water.Osmosis causes water to enter the plant cell, which results in swelling. However, the cell will not burst as the plant cell walls are made up of an extremely strong substance called cellulose. The swelling within the cell eventually stops, and at this point, the cell is said to be turgid. This process involving osmosis is important within a plant as it allows the stems to become strong and upright. There are many other cases where osmosis is responsible for the basic survival of living organisms. Here is a diagram which visually shows how osmosis will occur in this situation :

In my group we are going to perform our investigation by firstly taking five equally sized test tubes and a potato which we will take a sample of using a cork borer. Afterwards, we will cut five equal pieces of potato using a knife, so that they are more or less the same weight. Once we have weighed all the five pieces of potato, we will get the five different glucose solutions that will be used throughout the experiment. These solutions will consist of different molars of glucose. For example, there will be a solution of 0 molars, 0.2 molars, 0.4 molars, 0.6 molars and 0.8 molars. Using a measuring cylinder, we will measure accurately 10 ml of each solution and put it in the appropriate test tube which would have been labelled relavant...

...INTRODUCTION
Osmosis is the movement of water molecules from high concentration to low concentration through semipermeable membranes, caused by the difference in concentrations on the two sides of a membrane (Rbowen, L.). It occurs in both animals and plants cells. In human bodies, the process of osmosis is primarily found in the kidneys, in the glomerulus. In plants, osmosis is carried out...

Aim
To investigate the effects of increasing salinity on potatocell mass.
Background Information
This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a...

Introduction
In this experiment I am going to investigate the effect of varying concentration of a differing glucose solution on the amount of osmotic activity, between the solution and a potato tuber of a given size. The purpose of this experiment is to demonstrate how living cells rely on osmosis, the diffusion of water.

The aim of this investigation is to see the effect of varying concentrations of glucose solution on the amount of osmotic activity between the solution and a potato chip. An investigation into Plasmolysis in onion cells was undertaken prior to this...

...EXPERIMENT TO SHOW THE EFFECT OF DIFFERENTCONCENTRATION OF GLUCOSE ON POTATO STRIPS
INTRODUCTION: Molecules of liquid and gas are constantly in motion, they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move, they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called...

...glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used, I do not think it would have made a difference in the results. The mood of the person experimenting could possibly alter the results. For example, if a person is under stress, they may accidentally squeeze too...
