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 […]

Research Project

Calcium transport study of SF-9 lepidopteran cells and bull frog sympathetic ganglion cells ABSTRACT The intracellular calcium level and the calcium efflux of the bull-frog sympathetic ganglion cells (BSG) and the SF-9 lepidopteran ovarian cells were investigated using a calcium-sensitive fluorescence probe fura-2. It was found that the intracellular calcium levels were 58.2 and 44.7 […]

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 […]

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, […]
