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?’
whether temperature will damage and denature the permeability of plasma membrane.
The effect of temperature on the cell membranes of Beetroot cells.
To investigate whether temperature will damage and denature the permeability of plasma membrane.
Membrane Behavior Lab
The permeability of a cell to solutes in an aqueous medium depends upon the physical and chemical make–up of the membrane. The maintenance of the living cell depends upon the continued presence and functioning of a selectively permeable 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...

may lead to internal erosion of the base soil. A geotextile is an economical way to solve this problem using it as a filter to maintain the system permeability. A filter as a woven geo-textile has a mesh opening uniform and evenly distributed over the fabric. The coarser soil particles will bridge over...
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...

Step 2 - Take three of the 2mm discs of beetroot and cut them further into small...
To find out how the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out.
I predict that as the concentration...
The passive movement of materials across cell membranes is the result of a) the permeability of the membrane to the diffusing substance and b) the driving force. For uncharged compounds, the concentration gradient is the driving force between the inside and the outside of the cell. In...
Beetroot is one of many type of beets known as Beta Vulgaris.It can be used in cooking and drinking as it is one of the source of vitamins, minerals, nutrients and antioxidant as well including magnesium, potassium, sodium and vitamin C and betaine. Betaine in the cells serve as organic...
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...

Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane), however When beetroot is heated these red pigments...
BRIEF INTRODUCTION: Beetroot cells contain a red pigment stored in the cell vacuole in the membrane to prevent leaking out from the cell. In this experiment we used several solvents to calculate which one made the cell release more pigment.
RESULTS: A table showing the results of the intensity...

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...
