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

ORGANIC MATTER AND INORGANIC MATTE Organic matter is that which is living or has been alive‚ e.g. wood or coal. Inorganic matter is that which is not living and never has been alive‚ e.g. water or iron. Inorganic substances can be built up into organic compounds by living organisms. All living matter is made up of small units called cells. Some organisms‚ such as bacteria‚ consist of one single cell; others‚ like human beings‚ consist of many hundreds of millions of cells‚ all functioning together

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

Biological Membrane Study: HCl‚ NaOH‚ SDS Objective and Hypothesis: The objective of this lab is to determine the effects of SDS‚ HCl‚ and NaOH on red cabbage cell membrane. Prior knowledge can tell us that the red cabbage is a red-purple color due to a pigment called anthocyanin. This is what we will be testing in the experiment. We also know that HCl is a strong acid (very low pH) and that NaOH is a strong base (very high pH). From information learned in this course (lecture/lab) we can assume

experiment. I want to find out what effect temperature has on the permeability of a cell membrane. Controlling other Variables- I will use measures to ensure that everything stays the same in my test to gain the best and most reliable results possible - Same volume of water that I put the beetroot into after heating. - The beetroot I use will be the same size each time‚ I will ensure this using a cork borer. - The beetroot will be heated for the same time for each one‚ also it will be left in the water

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

Investigate factors affecting cell membrane permeability in beetroot. Research Question: How does variation in temperature affect the permeability of cell membranes? Background Information: In this investigation I will want to identify how variations in temperature effect the permeability through the use of a beetroot. I predict that as the temperature of the water increases so will the dispersion of the pigment. Independent Variable: The temperature of water will be increased in increments of 10oC

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
