Do various different temperatures affect a cell membranes permeability it is thought that if the temperature increases then so does the beetroots cell membrane permeability, which can be seen by the optical density of the solution dipped with the beetroot sample. Investigating the effect of temperature on the permeability of the cell membrane of beetroot 5088 words | 21 pages investigation i will be measuring the effects of temperature on the membrane permeability of beetroot.
A decrease in temperature can also have a negative effect on cell membranes and cells at low temperature, the fatty acid tails of the phospholipids move less and become more rigid this decreases the overall fluidity of the membrane, also decreasing its permeability and potentially restricting entry of important molecules such as oxygen and. An investigation to determine the effects that various temperatures have on beetroot membrane using colorimetry abstract/aim the aim of this experiment is to look at how temperature has an effect on the movement of pigments through a beetroot membrane, this will involve investigating how the membranes in the beetroot will split and leak the red pigment, anthocyanin.
Fill 8 boiling tubes each with 10cm³ of distilled water and place them into 8 separate water baths of different temperatures (eg 0°c, 10°c, 20°c, 30°c, 40°c, 50°c, 60°c, 70°c) once at the desired temperature, add a piece of beetroot to each boiling tube and leave for 30 minutes. The effect of temperature on the cell membrane of a beetroot essay sample aim in this experiment i will be testing the effect of temperature on the plasma membrane of a beetroot. Different temperatures of water bath was used so that we can see the effect of temperature on the beetroot cells clearly the temperatures used are 25°c, 35°c, 45°c, 55°c and 65°c the responding variable in this experiment is the reading of absorbance by the spectrophotometer of the dye solution. : the effect of temperature on membrane : : : : lecturer’s name : practical date submission date : : objective to investigate the effect of temperature on membrane structure to practice experimental and investigative skill introduction beetroot the beet (beta vulgaris) is a plant in the chenopodiaceae family.
If beetroot is not available, use discs of red cabbage you will need ten or more discs for each tube if it is not possible to prepare beetroot in advance, students could cut the cores/ chips at the start of the lesson, wash in distilled water and blot dry 2 note: beetroot juice will stain clothing (and, temporarily, skin) but is not hazardous students may wish to wear labcoats to protect their clothing from stains. - an investigation to show how water temperature and alcohol concentration affect membrane permeability aim the aim of the experiment is to show the cell’s membrane permeability is affected by being placed into different temperatures of water also the effect of placing beetroot in to different concentrations of alcohol.
The effect of temperature on the permeability of beetroot membrane 874 words | 4 pages the effect of temperature on the permeability of beetroot membrane analysis the graph shows the colorimeter readings increase as the temperature increases, they increase by the most at higher temperatures this is shown by a smooth curve. The effect of temperature on the permeability of beetroot membrane 874 words | 4 pages effect of temperature on the permeability of beetroot membrane analysis the graph shows the colorimeter readings increase as the temperature increases, they increase by the most at higher temperatures. Investigating the effect of temperature on the permeability of the cell membrane of beetroot 5088 words | 21 pages investigation i will be measuring the effects of temperature on the membrane permeability of beetroot i will be measuring the amount of anthocyanin that will diffuse out of the beetroot. A cut bores of beetroot with a size 4 cork borer and soak overnight in a beaker of distilled water (note 1) b set up a series of water baths at different temperatures investigation procedure c collect 3 or 4 beetroot cores from the beaker provided cut each core into 2 cm sections until you have enough for one core for each temperature of water bath that you will be using.
