investigation is an indirect study of the effects of different substances and treatments on living beetroot cells. Beetroot cells have been chosen for this activity because each beetroot cell has a large central vacuole bounded by a membrane (Figure 1). Contained in the vacuole is the red pigment anthocyanin‚ which gives the beetroot its typical colour. The whole beetroot cell is also surrounded by the cell membrane. If the two membranes remain intact the anthocyanin cannot escape into the surrounding

These alleles are found at particular places on the chromosomes called loci. During meiosis
