effect of temperature on cell membrane structures Procedure SAFETY: Always carry scalpels clasped to a tile and with the tip pointing away from you. Beetroot cells contain pigments called betalains that give the tissue its dark purple-red colour. The pigment is contained in the cell vacuole. Investigation a. 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

The tissue used is from the taproot of a beetroot‚ and the effect on the membrane’s permeability assessed by the amount of pigment leakage that occurs. Hypothesis ========== I predict that the most damage to the membrane will be caused by the acid or the boiling water. I think

Hypothesis: Increasing the temperature and pH levels which the beetroot membrane cells are exposed to will increase the amount of dye that passes out of the membrane.

Beetroot Beetroot is a brilliantly versatile veggie. There are many ways to eat it including the traditional pickled beetroot but also more modern recipes such as marinated beetroot with grilled goat’s cheese and creamy beetroot risotto. To grow beetroot‚ sow 2 seeds every 10cm (4 inches) into a 2cm (0.75inch) deep trench. The children will enjoy using a stick to make the trench

The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)
