The Effects of Temperature on Beetroot Cell Membranes Argumentative

Tube was removed and the water in the test tube was tipped out. 10ml of tap water was then added to it and then left to stand in the test tube rack. The beaker was then heated to 35c. The burner was then turned off and the water’s temperature was left to rise to 40c. […]

What affects membrane permeability

Cell Membrane Permeability Practical Investigation This experiment investigates the effect of changes in pH, alcohol and different concentrations of detergents on beetroot membrane. If the extreme levels of pH would degrade the beetroot cell membrane, the experiment would prove that different solutions react differently. Introduction Cell membranes are the entry points for liquid solutions. They […]

The Effects of Temperature on Beetroot Cell Membranes

Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water, it is on the outside of the cell, the […]

Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage

Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage By: Trevor Sandum, Lab 2, March 9, 2013 Introduction: A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk, 2013). The membrane is necessary for sustainability of the cell’s life, it […]

Investigating Membrane Permeability

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. The pigments will be automatically extracted from the vacuole when the membrane is […]

The Cell Membrane

The Cell membrane surrounds all living cells and is the most important organelle, there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the […]

Factors Affecting Cell Membrane Permeability

Aim: to investigate the factors affecting cell membrane permeability of red cabbage, using absolute alcohol (10 cm3), 1 M hydrochloric acid (10 cm3), 1M sodium hydroxide (10 cm3), and distilled water (10 cm3), and change of temperature (40 oC, 65 oC, 100 oC)Hypotheses:If the leaf discs are not rinsed, the distilled water will change colour, […]

Proteins of the Red Blood Cell Membrane

The aim of this experiment was to find the major proteins that make up the plasma membranes of cells, their whereabouts within the membranes, and what effect various pre-treatments would have on these proteins. It was the erythrocyte membrane that was studied in this experiment because red blood cells can easily be extracted from whole […]
