effect of variation in temperature on the permeability of cell membranes using fresh beetroot Aims 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. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly objectively using

permeability of beetroot Hypothesis Organic solvent and high temperature will destroy the cell membrane and make it permeable to the red pigment. The higher the concentration of the alcohol‚ the greater will be this effect. Principle Beetroot is the material used in this experiment to demonstrate the effects of high temperature and chemicals on the permeability of the cell membranes. Beetroot contains a red pigment called betalain‚ which is located in the large central vacuole of the beetroot cells.

fatty acid composition. This means that at temperatures below this critical point no dye in the beetroot cell would be able to leak from the cell and would not change the colour of the surrounding water. The phospholipids also undergo phase changes at higher temperatures causing the membrane to be more permeable thus allowing the red pigment to move more freely into the water surrounding the beetroot.

Canker sores are painful‚ open sores on the inside of the mouth and cheek. They may be white or yellow. The sores usually heal in 1 to 2 weeks. Women are more likely than men to have recurrent canker sores. CAUSES The cause of canker sores is not well understood. More than one cause is likely. Canker sores do not appear to be caused by certain types of germs (viruses or bacteria). Canker sores may be caused by: • An allergic reaction to certain foods. • Digestive problems. • Not having enough

Biology A - Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and

Investigating the effect of salt concentration in beetroot at different temperature Abstract The aim of the experiment is to find out the effect of salt concentration in a beetroot at a different temperature. The experiment will help to identify the effect of salt concentration in beetroot at different temperatures. After this‚ equipment called colorimeter will be used to take a reading for absorbency. The readings for the absorbency will be repeated three times in order to find the mean of

Independent variable: Temperature of beetroot Dependent variable: Absorbency of light Hypothesis: As temperature rises to its optimum temperature‚ the absorbency of light will increase because protein is an enzyme and will therefore be affected by temperature. This is because more beetroot dye will pass through the cell membrane and then into the distilled water. The deeper the colour of the beetroot dye‚ the higher the absorbency of light. Beetroot vacuoles have red pigments which can’t
