Activity 2.8Theeffect of temperature on membrane permeability in beetroot
Aim and Introduction
Within the vacuole of the beetroot cell, a pigment, known as betalain [or anthocyanin], can be found. Betalain pigments give beetroots their deep red colour and are recognised as antioxidants, which may...

A Moral Story: The Red Hen and Her Friends
Once, there lived a hen with her five chicks. The hen was as red as beetroot. She had three friends: a duck, a cat and a dog. They all lived happily.
One day, the red hen stumbled on to a wheat seed. “Hey, who among you wish...
Title Membrane Permeability
Aim To determine the effect of various chemicals and high temperature on the membrane permeability of beetroot
Hypothesis Organic solvent and high temperature will destroy the cell membrane and make it permeable to the red pigment. The higher the concentration of the...
Beetroot Experiment Write-Up
Hypothesis: The higher the temperature, the more permeable the beetroot will be.
Independent Variable: The temperature of each test tube.
Dependant Variable: The transmission of light through the beetroot water.
Control Variables: The volume of distilled...
What was for Lévi-Strauss a symbol of cultural homogenisation has paradoxically been elevated to the status of an Australian icon: the beetroot has come to be recognised as the distinguishing ingredient of the classic Australian milkbar hamburger. At the same time, this unassuming vegetable has been...
Cell membrane permeability experiment
With temperature and pH
To investigate the membrane permeability with different temperature & pH (acid and base)
Predict that the most damage to the membrane will be caused by the
acid or the boiling water...

Investigating the Effect of Temperature on the Permeability of Membranes
The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents, for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances...
effect of the organic solvents on the cell membrane of the beetroot
To investigate the effect of different organic solvents, such as alcohol and paraffin oil, on the cell membrane of the beetroot by using the red pigments in the beetroot as indicator.
Organic solvents dissolve...
The effect of temperature on the permeability of cell membranes
For my coursework, I intend to assess how temperature affects the plasma membrane of a cell. For this I will use the cell of a beetroot.
What is a cell membrane?
The cell membrane, also called the plasma...
Concentration (cont.) has
on Membrane permeability of Beetroot cells.
Hypothesis: I predict that as detergent concentration increases, the
solution will become less clear, plus mass increases. The increases in
mass will indicate that the water potential of the Beetroot cell is
lower than that of the...
An Investigation to determine the effect of temperature on cell
This investigation involves the estimation of the extent to which a red pigment present in the cell sap of
beetroot storage tissue, passes out in defined circumstances, when the tissue is immersed for...
Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using...
temperature on the permeability of cell membranes using fresh beetroot
In this investigation, you will subject fresh, washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane.
The beetroot discs will be placed...
Title: An experiment to investigate how temperature affects the Permeability of beetroot cell membranes
(Description )Beetroot cells contain a red pigment, which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell...
scapel to cut the cylinder of beetroot into 15 discs of 2mm each. Make sure this is done on the white tile to so as to minimize the probability of hurting oneself and that one is holding onto the beetroot using the forceps.
Step 2 - Take three of the 2mm discs of beetroot and cut them further into small...
Hypothesis: To investigate the effect of different concentrations of ethanol on the permeability of beetroot cell membranes.
Prediction: By exposing a membrane to a solvent, ethanol, it will increase its permeability. So the higher the concentration of the solvent, the more permeable the membrane...
temperature on the membrane permeability of beetroot. Since I was unfamiliar with this experiment, I first conducted a preliminary test. I considered my preliminary test as my trial for this experiment. My Hypothesis for this experiment was to found out the amount of pigment loss of beetroot when exposed to varying...
Beetroot Practical 2.8
An investigation to find out whether the raise of temperature will increase the permeability of the cell membrane:
The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’
Membrane Permeability under Stressful Conditions
Membrane permeability is a primary function of the cell. This experiment tests the limits at which permeability will function in beet root cells. Beet roots were chosen because of the betacyanin that is stored in the cells. As the cells became...
