Part 1 Part 1 of the experiment 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

Planning AIM Beetroot cells contain a red pigment‚ which is stored in the cell vacuole and a vacuole membrane to prevent this leaking out of the cell surrounds it. The outer of the cell is also surrounded by a membrane‚ which again helps contain the pigment inside the cell. In this experiment I aim to find out the relationship between the leakage of red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot cells accurately

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 are phospholipid bilayers meaning they are composed of lipids and proteins. The membrane-bound organelle‚ vacuole‚ in a cell is accustomed to maintain structure and

Implementation My aim for this experiment was to find the effect of temperature on the membrane permeability of beetroot. Since I was unfamiliar with this experiment‚ I first conducted a preliminary test. I considered my preliminary test as my trial for this experiment. My Hypothesis for this experiment was to found out the amount of pigment loss of beetroot when exposed to varying temperatures. Betalain pigment found in beetroot My method for this experiment is:- * Use a cork borer to cut about

Control process Beetroot samples: The same size beetroots will be used throughout the experiment this is to ensure that the impact of the temperature on every sample will stay the same‚ i.e. if having a bigger beetroot sample less pigments will be released into the test tube at lower temperature‚ or having a smaller beetroot sample more pigment will be released into the test tube. This error will change the results of the experiment at large. Therefore it is important to insure the sample sizes

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the 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

the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out. Hypothesis I predict that as the concentration of ethanol goes up‚ the permeability will increase as the ethanol will slowly dissolve more phospholipids (lipid bilayer) and so more anthocyanin (the beetroot juice) will leak out of the membrane. So at 10% concentration

Beetroot Practical 2.8 An investigation to find out whether the raise of temperature will increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can
