Osmosis: Potato and Sucrose Solution
Words • 2054
Pages • 8
Investigation of Factors Affect Osmosis in Potatoes Aim The aim of the following experiment was to investigate the effect of  varying the concentration of sucrose solution on osmosis in a potato. Preliminary Experiments One preliminary experiment was done before the main experiment. From  the preliminary, we were trying to find out how osmosis actually  occurred in potatoes, and gave us a vague idea on what the main  experiment would be like. This preliminary will aid my prediction, which is stated…...
Investigating the Water Potential of Root Vegetables
Words • 2409
Pages • 9
For my experiment I will be investigating the water potential of root vegetables. The vegetable I am going to use is turnip. I am going to use turnip because it is a uniform vegetable. This investigation is about osmosis. "Osmosis is the net movement of water molecules from an area of high water potential to an area of low water potential. This takes place through a partially permeable membrane." Water potential is the potential energy of the water molecules on…...
Find out what affects the rate of Osmosis

My Aims * I am aiming to find out what affects the rate of Osmosis. * To do this I am going to use temperature as a variation and my aim is to use it successfully. Prediction I predict that the warmer the water, the faster the rate of Osmosis occurs. I believe that Osmosis will occur when the water is at 10 but when the water temperature increases to higher temperatures e.g. 50 I believe a greater amount of…...

Determining the Rate of Osmosis with Water and Sucrose 10/3/2012 Determining the Rate of Osmosis with Water and Sucrose Author: Results: Bag 1 had a rate of osmosis equal to 0. 01 grams per minute. Bag 2 had a rate of osmosis equal to 0. 0543 grams per minute. Bag 3 had a rate of osmosis equal to 0. 0471 grams per minute. Bag 4 had a rate of osmosis equal to 0. 0886 grams per minute. Bag 5 had…...
Diffusion, Dialysis And Osmosis
Words • 575
Pages • 3
In Diffusion, Dialysis And Osmosis lab, we discovered that we were going to observe and understand the conditions under which diffusion, dialysis, and osmosis occur. Then we constructed models of diffusion, dialysis, and osmosis. We predicted that the direction of change would be from the membrane to the beaker. We understood how these processes affected the selectivity of the cell membrane. The second part of the lab was dealing with dialysis. In this part we studied starch and sodium chloride…...
Osmosis Lab Report

Pages • 4
Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable, to study the effects of osmosis on a model cell, and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives, we had to fill the dialysis tubing with either water, or different amounts of sucrose. We then tied off the tubes and put them into…...
Osmosis & Diffusion
Words • 354
Pages • 2
Kinetic energy, a root of energy stored in cells, causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water likely. Water potential…...

These two Case Studies come from a National Center on Case Studies. I think that a case study approach is very useful in applying knowledge and this is what makes you learn it better. They may be a little daunting when you read them but I will help you go through them. Please ask for help so this topic becomes more enjoyable for you. Part I—Too Much of a Good Thing Times were difficult in Habersham County. The skyrocketing prices…...
Scientific Critique of “Osmosis Jones”
Words • 2721
Pages • 10
SYNOPSIS The 2001 film, "Osmosis Jones", focuses on the representation of the human organism and the daily conflicts a body faces in order to maintain function. The film "Osmosis Jones" is a film that tries to capture the attention of children ages eight to fourteen, by exposing the mechanisms of the human body. It is able to reveal the dangers of maintaining an unhealthy diet and some of the consequences that are associated by doing so. The film illustrates that…...
Osmosis and Selectively Permeable Membrane
Words • 358
Pages • 2
Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another ( Reece,…...
Experiment to Investigate Osmosis in Potatoes
Words • 2789
Pages • 11
The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements: It is the passage of water through a semi permeable membrane It is…...
Effects of Osmosis in Plants’ Cells
Words • 984
Pages • 4
Introduction Osmosis is a movement of water across a semi-permeable membrane. This may only happen when there is a difference in concentration between the two sides of the membrane. The water moves from low concentrations to high concentrations. That is because the low concentrated area tries to dilute the opposite via osmosis. The effects osmosis has on a cell are either that it becomes turgid and hard as water enters the cell or it becomes dehydrated (this is called plasmolysing…...
To investigate the effect to the potato cells in the different solute concentration water
Words • 766
Pages • 3
Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell, the water will move into the cell. However, if the concentration of inside the cell is lower than the outside, water will not move into the cell. This process is called osmosis. Research question; This investigation will determine how different concentrated sugar water will affect to the mass change…...

1. Diffusion and Osmosis, June 4, 2013 2. Purpose: The purpose of this laboratory is to help provide visual understanding of diffusion which is a service of high concentration spontaneously (no energy required) moving to an area of low concentration. Likewise having a look at osmosis, which is the motion of chemicals throughout the cell membrane. Osmosis needs some kind of energy to be put in for this to take place. After these experiments we should have a much better…...

The basic principles of Osmosis and Diffusion were tested and examined in this lab. We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion, and in a biological context, we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1. Investigate the process…...
