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 of the pigment and why

drinking and though she is well aware of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. 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

leaks out of beetroots soaked in alcohol Planning Aim: - to investigate the effects of different concentrations of alcohol on the membrane structure of a beetroot a) Decide what you think will be the effect of alcohol on beetroot cell surface membranes and how this will affect their permeability. Write down your idea as a hypothesis that you can test‚ and support your idea with biological knowledge. Hypothesis “The greater the concentration of the alcohol the more red pigments (betalains)

concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration of ethanol the more permeable the cell membrane will become. Introduction: The cell membrane is a thin semi permeable

investigated the effect of different temperatures on beetroot cell membranes (a type of plant cell). Through this experiment‚ the process of diffusion and osmosis was in action. Various temperatures ranging from low temperatures to high temperatures such as -5⁰C‚ 5⁰C‚ 30⁰C‚ 50⁰C and 80⁰C were used to investigate the temperature effects on beetroot cell membranes. The hypothesis predicted that the higher the temperature the darker the beetroot substance and the lower the temperature the least colour

PRODUCTION OF CARBON PAPER USING CHARCOAL AND BLACK MIX OF USED BATTERY AS PIGMENT D EPARTMENT O F S CIENCE IN COOPERATION WITH THE AND T ECHNOLOGY ABSTRACT The objective of the first part of the study was to find the best ratio of ink using carbon from used batteries and charcoal as pigments. The ink was evaluated on the basis of how much pigment is suspended in the mixture and their shelf life. The second part was aimed at the production of carbon paper. The best kinds of ink were tested

5.5 Candy Chromatography Background Information: Paper Chromatography is a separation tool in which pigment is put on a paper made of cellulose and water‚ and placed in a solvent‚ in this case isopropyl alcohol. Due to capillary action‚ the solvent crawls up the paper‚ separating the pigments. This technique is used to identify components of a mixture‚ even unknown ones‚ and can be used to isolate components into pure samples. Real world uses of this technique includes identifying certain biomolecules

Background Information and Research Paper chromatography uses selective adsorption on a strip of paper. It is used for separating and identifying mixtures that are or can be colored‚ especially pigments. This can also be used in secondary or primary colors in ink experiments. Is it used for Contaminants in rainwater‚ Analysis of narcotics‚ and Detection of substances in urine. Purpose • The purpose of this lab is to see the separation of dye on the candy.
