Ben Zaré 9MK Biology Investigation - Osmosis in Potato Cells 9/7/04
Section 1 Planning
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...
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...
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...
My objective is to plan and conduct an experiment from which I should be able to draw a firm conclusion that will either prove or disprove any predictions I make. This essay aims to asse...

In this project, the relationship between the concentration of salt solution and the length of the potato strip that was immers...
Biology laboratory work: Osmosis observation
Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution
By Jonas Kulikauskas
Siauliai Didzdvaris Gymnasium
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 in Plant Cells

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...
BIOLOGY OSMOSIS LAB REPORT
1. Research Question/ Aim
How do the different sodium chloride concentrations of solutions affect the length (measured in mm) and mass (measured in grams) of potato cores placed in them overnight (approximately 10 hours)?
NAME: IZYAN NABILA BINTI AHMAD `AZAM
TITLE: Transport across membrane
OBJECTIVES: To investigate the effect of concentration of blackcurrant squash on osmosis in chipped potatoes.
In biology, osmosis is...

[Osmosis Practical Report]
The purpose of this investigation is to see if the concentration of Sodium chloride (NaCl) solution will affect the mass of the potato cylinder hence the rate of osmosis. This can be done by placi...
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,...
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...
