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...
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...
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...
Investigating Effects of duration of heating on permeability of beetroot cell membrane
Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer, which is the basic structure of the membrane...
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...
regular, increasing pattern to see how this effects my chosen plant; beetroot. I predict that the higher the temperature the more cell damage will occur to the membrane therefore allowing more color to leak out.
Beetroot is a vegetable, which is used greatly in food making and an important...

What is the effect of temperature on membrane permeability on beetroot as measured by absorbance of pigment?
Membrane permeability is affected by the structure of the membrane. Within the membrane, there is cholesterol and proteins maintaining the structure of...
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...
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?’
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...
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...
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...
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...
the number of magnetic field lines
passing through the region.
The ease with which a material will conduct magnetic lines force is called permeability.
An electromagnet is a type of magnet whose magnetic field is produced by the flow of electric
current. The magnetic field disappears when...
A STUDY OF CELL MEMBRANE PERMEABILITY IN A BEETROOT.
AIM: To investigate the effect of different type of ethanol concentration in the beetroot cell membrane.

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...
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...
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...
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...
Investigating the effect of temperature on the permeability of cell membranes
The aim of the investigation is to investigate the effect of temperature on the permeability of membranes. To do this I will place cubes of cut up beetroot into a test tube with 5cm³ of distilled water. Then I will place...
