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.

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...

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.

Like any other design process, site development starts with the analysis of the existing situation and the design probl
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

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

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.
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 surrounds it. The outer of the cell is also surrounded by a membrane, which again helps contain the pigment inside the c
