Biology GCSE Coursework: Osmosis in Potato Chips
Skill Area P: Planning
Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size.
Hypothesis: Osmosis is defined as the net
GCSE Biology: Osmosis in a Potato
To investigate the effect of placing a piece of potato in a given strength of sugar solution.
I predict that, as the solution becomes more concentrated the more the cell will shrink, as the water, of higher concentration inside the potato cells, f

What is the aim of your experiment? What do you want to find out?
The aim of this experiment is to investigate how potato tissue changes when placed in sucrose solution
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

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
Observing Osmosis in Potato Cells
Purpose: To observe the effect of osmosis on plant cells.
Hypothesis: The higher the salt content of the water, the lower the mass of the potato.
Variables: Independent: the salt percentage of the solution
Dependent: the weight of the potato in

Hypothesis: The more sugar in solution, the more potato mass will decrease.
Aim: To see how potato m
Controlled Assessment: Osmosis of a Potato
Osmosis: Osmosis is the movement of substances through a partially/semi permeable membrane from an area of high concentration to an area of low concentration to balance of the concentration of the two sides.
Biological membranes do allow wate
A.P. Biology Lab: 1. Osmosis
a. Purpose: The purpose of this lab was to observe the diffusion process of water, osmosis, as well as create an understanding of water potential, the basis of osmosis. The experiment proved how water molecules i
Osmosis is a specialised form of diffusion. Water moves from an area of LOW concentration of Solute to an area of HIGH concentration of solute through a semi-or fully permeable membrane by the process.
Water moves constantly through the cell's membrane its estimated that about 250 times the volum
Osmosis in Potato Cells Investigation
The purpose of this experiment is to look at the effect of concentration of sucrose solution on potato cells.
Osmosis is a special kind of diffusion and involves the movement of water molecules through a partially permeable membrane from a w
Osmosis and Diffusion Lab
Diffusion is vital to many life functions of a cell, it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion,

Which saltwater concentration will have the most damaging effects on potato cells?
Osmosis is the diffusion of water across a selectively permeable membrane. Generally, water moves from a lower solute
