EXERCISE 1C: Determining the Water Potential of Potato Cells
Introduction: Water potential was defined above as an expression of the tendency of water to diffuse from one region to another. Water potential is a numerical value that must be determined for a given temperature and pressure. In this
The Effect of Salt Concentration on Osmosis in Potato Cells
We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material, which allows some things to pass throug
Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment, a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to meas
Osmosis and Diffusion Lab using Potato Cores
Determine if there will be a difference of the movement of water through the potato cores in sucrose solutions of different concentration.
The process of water passing through the cell membrane is called osmosis. Th

Using Sucrose Solutions to Determine Osmolarity of Potato Tubers Based on Weight
By Thomas Pelikan
October 2, 2012
In this experiment we were trying to determine the osmolarity of potato tubers by weighing them before and after incubati
Lab Report on Diffusion and Osmosis Our objective is to figure diffusion and osmosis. Diffusion is the process whereby particles of liquids, gases, or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region o
Osmosis and water potential
Aim of the experiment:
Finding the water potential of potato.
Independent variable: concentration of the solution.
Dependent variable: percentage changed in weight of the potato strips.
Controlled variable: size of the potato strips, i
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
Michael Castelli Keegan Bauman
Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis, which is a transport mechanism. In this lab the probl
The Relationships between Osmosis, Osmotic Potential, Concentration, and Density Introduction Now, the goal of this lab was to find the osmotic potential of the potato cells. Each of the five solutions can either be hypotonic, hypertonic, or isotonic to the potato cell. If a solution is hypotonic,
Osmosis in Potato Tubers
When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment, its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or

1). What is energy? = The capacity to cause change, especially to perform work. Kinetic and Potential energy? = Kinetic Energy = The energy of motion; the energy of a mass of matter that is moving. Pote
How does the mass of a potato slice change when it is put into distilled water, tap water or salt water?
Background: In this lab we will find out how water with different concentrations affects the mass of a potato slice when the slice is soaked in the water. In this lab the effects of osmosis
Potato Cell Cytoplasm Composition
PURPOSE: To determine the concentration of salt in the cytoplasm of potato cells
HYPOTHESIS: Increase in salt concentration results in a hypotonic solution where the mass of the potato increases due to the movement of water into the cell. On the other...
My name is Seamus O'Malley and I emigrated to the United States of America due to the horrible potato famine Ireland is facing, I am better known as a "potato famine" immigrant. I am writing this journal entry in an effort to inform others and shed some light on the struggle we Irish immigrants had
In order for cells to interact with their environment, molecules must be able to move through the cell membrane. Movement within the cell occurs by diffusion. Molecules move through the cell membrane by osmosis. Diffusion is the movement of molecules from a region of hi
The movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent, each containing different concentration levels, then the water would move along its concentration gradient until each side of the membrane are equal. The wate

Sucrose solution (0.2,0.4,0.6,0.8,1.0)
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 o

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION 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 sp
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
From our graph it can be seen that the concentration of sucrose solution is 0.18 M at 0% change i
Humans have to exchange with their environment in order to stay alive and get all the nutrients and air they need. Cells, just like humans, exchange molecules with its surrounding by two processes call diffusion and osmosis. These two processes can occur due to the selective permeabl
Sports Drinks and Their Effectiveness
Sports drinks were first invented in order to combat dehydration. When the body loses water through sweating, many nutrients are lost as well. Depending on the severity of dehydration, a wide range of symptoms can occur from impaired performance to circula
