concentration of betacyanin when placed under these various stresses Introduction: The Beta vulgaris craca plant‚ commonly referred to as the beet root contains a pigment‚ red in colour‚ called betacyanin. The betacyanin’s containment within the cells of the beet root cell relies on the stability of the plant’s membrane structure. The manipulation of the cell’s membranes through temperature change and solution treatments often causes damage to the vacuoles within the cell which contain betacyanin. Poovaiah

BEETROOT PIGMENTS - and membranes – These pigments are betalain pigments (not‚ as often thought‚ anthocyanins)‚ which they replace in some organisms. They are named after the Beet family of plants (Beta) but are also found in fungi (Fly Agaric - the red‚ spotted one!). In petals they presumably attract pollinating insects and may be present in seeds/fruits to encourage birds to eat them and so disperse the seeds. Man has selected for colour in beetroot‚ both because

The Effect of temperature on beetroot This experiment is designed to investigate the effect of varying temperature (centigrade) on beetroot and its cells. My earlier experiment suggest that as temperature increases the integrity of the beetroot cell membrane will be destroyed and a subsequent release of beetroot pigment will be released into its surrounding milieu(in this case distilled water). In the experiment I will examine if my hypothesis (above) is correct. In order to conduct this experiment

When a beetroot cell is exposed to various kinds of temperatures‚ its plasma membrane is affected and may change in structure resulting in the leaking of betacyanin. If the temperature changes‚ then I would expect to observe that there would be a change in the concentration of betacyanin that has leaked from a beetroot cell. In specific‚ at high temperatures‚ the phospholipids that make up the plasma membrane of the beet root cell become progressively more destabilized causing them to transform into

Keywords: beet root model system‚ spectrophotometer‚ betacyanin‚ cellular membrane‚ phospholipid Abstract The cellular membrane separates and protects the cell acting almost as a wall. Depending on what stressors there are the cellular membrane can become damaged. The objective of this experiment was to examine the structure of the cell membrane using the beet root model system by observing the effects of solvents on the beet root. The beet root was placed in seven solvents to see if the beetroot would leak any of its color to see if the membrane was damaged and by

Why does belatin leak out of cooked Beetroot? In cooked beetroot‚ the water or food would become stained due to its leakage of betalin (the redish-purple pigment). Betalin is found in the vacuole of beetroot cell. The leakage may have been caused by something happening in the cell membrane of the beetroot – concerning the proteins embedded in the phospholipid layer. The study will require the experiment of different temperatures of water and to find out which in temperature causes the most leakage

Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes
