The Effect of Surface Area on the Osmosis Rate of a Potato Essay

Introduction Osmosis involves the movement of water molecules from an area with more pure water to an area that has less pure water. The water molecules must pass through a membrane. The goal is for the water to be equally dispersed throughout. There are different types of solutions that osmosis may take place in. Things such as temperature, light and surface area will affect how optimally the osmosis process will work. Reverse osmosis can be used to create systems that purify water. It can also

Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially

affect the weight of pieces of potato after osmosis has taken place? Aim The aim of this is experiment is to investigate how much sucrose is in a potato. We are going to investigate the effect of different concentrations of sucrose on the weights of pieces of potato after osmosis has taken place. Prediction I predict that the less concentrated the solution of sucrose is, the greater the weight of the potato will be. I predict this because osmosis is the movement of water from a

kinetic energy, from an area of higher concentration to an area of lower concentration. Once the two substances are in equilibrium, diffusion still occurs. However, the substances stay in equilibrium, as the random movement is equal across both sides. Osmosis is the diffusion of water, through a selectively permeable membrane. A selectively permeable membrane is a membrane that allows certain molecules to pass through itself, and is resistant to other molecules. Osmosis is a very important process

Investigate the Effect of Varying Solution Concentration on Osmosis in a Potato Chip Prediction A definition of osmosis is: 'the movement of water molecules from an area of high water concentration to a low water concentration across a semi-permeable membrane' (Oxforddictionary 2000). In a high concentration of water the amount of solute (e.g. sugar) is low. These solutions are usually known as a dilute or weak solution. But in a low concentration of water the amount of solute (e.g. sugar) is

Discussion: Effects of Osmosis on Potato Cell: In the first experiment of the Osmosis and Potato Lab, two slices of potatoes were used to analyze how the extracellular fluid of a cell membrane effects the net movement of free water molecules in and out of the cell. The first potato slice was used as the control, while the other potato slice was sprinkled with salt, after leaving both slice to set for 10 minutes, the potato slices with the salt was more dry and shriveled than the control. In this

An investigation to find the water potential of potato and carrot tubers in a sucrose solution, of concentration 0.00 – 0.50Mol, over a 24 hour period Interpretation Written Communication C1 From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change in mass for the potato and 0.355 M at 0% change in mass for the carrot. I will use these values to find the solute potential by using the calibration graph. I will work out the water potential by using the

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.   Osmosis is the movement of water molecules (H20) from a region in which they are highly concentrated to a region in which

Solution affects the Rate of Osmosis Introduction: Diffusion is the movement of particles from a high concentration to a low concentration until they are spread out evenly. An example of diffusion is when an aerosol is sprayed. The particles spread out from the high concentration at the nozzle into the rest of the room and that is how the smell moves. Osmosis is the passage of water molecules from a weaker solution to a stronger solution through a partially permeable membrane. Osmosis is a type of diffusion

There are four types of main tissues in human body 1. Epithelium – Epithelium tissues are composed of layers of the cells that are closely packed together which is specialised to form the covering or lining of both external and internal surface of body such as surface of your skin and internal digestive system. The main function of epithelium tissues are to provide protection like skin that protects you from injury, secretion like glands such as enzymes, and to absorb materials like intestine such
