Lloyd James (13.3) 16th March 2001 Biology A-Level Coursework Planning Experimental Procedures Design an Experiment to show that an increase in temperature influences the release of red pigment from beetroot 1. Design an experiment 2. Analyse 3. Produce a hypothesis that would enable a cell biologist to account for the result Equipment needed: Water tank, Test tubes, Test tube rack, Cork Borer, Beetroot, Colorimeter, Stop Clock, Scalpel, Forceps, Tile, Spatula, Thermometer, Ruler, Sharp Knife Investigating the effects of temperature on the release of red pigment from beetroot, will consequently distinguish the effects that temperature has on the permeability of a cells membrane. The cells inside beetroot tissue contain in their vacuoles a water-soluble and a radiant red pigment which is an anthocyanin derivative, surrounded by a specialised vacuole membrane called a tonoplast. This red pigment can be detected easily by the eye and its concentration measured using a colorimeter (Clegg and Mackean, 1995). Using this acquired knowledge, and my...
