2.8 Investigating why the colour leaks out of beetroots soaked in alcohol
- to investigate the effects of different concentrations of alcohol on the membrane structure of a beetroot
a) Decide what you think will be the effect of alcohol on beetroot cell...
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 u
The effect of temperature on membrane permeability in beetroot
The colour of beetroot is due to the presence of a red pigment, anthocyanin, in the cell sap. You are going to investigate the effect of temperature on the selectively permeable membranes of beetroot.

Aim: To investigate how effect of Detergent 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 potent

The effect of alcohol concentration on the cell membrane
In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol, results in more damage done to the...
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?’
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 memb

To investigate the effect of variation in 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.
Investigating Membrane Permeability
Reason for choosing beetroot as the object of experiments
Beetroot is usually used as the membrane ‘disruption’ experiment. It is because of beetroot has more pigments in their vacuole. These pigments show how variables damage the membrane of beetroot. Th

The aim of this investigation is to find out what the effect of temperature can have on plant cell membranes . For this experiment I will be using different temperatures ranging from below 0 to 80 Celsius in a regular,...
In what way do the various membranes of a eukaryotic cell differ? Phospholipids are found only in certain membranes. Certain proteins are unique to each membrane. Only certain membranes of the cell are selectively permeable. Only certain membranes are constructed from amphipa

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 be
