Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

Hooke could see the cell walls‚ but there was no indication of a nucleus and other organelles found in most living cells. Something similar to what Hooke would of observed‚ a cork under a microscope. In 1774‚ a man named Anton Van Leeuwenhoek‚ also referred to as the “Father of Microbiology”‚ a Dutch tradesman and

the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot using a cork borer‚ I will slice them into a certain width and then place them into distilled water at different temperatures. Using a colorimeter I will measure the anthocyanin that will diffuse into the distilled water‚ the higher the reading of the colorimeter
