Each species, possessing genotypic specificity and his characteristic degree of plasticity, reacts differently to their environment. Bioindication at the tissue and cellular level is based on a narrow range percolation biotic and physiological reactions. Its advantages are high sensitivity to disturbances, which allows to identify even small concentrations of pollutants, and to identify them quickly. It is at these levels is possible with the earliest detection of violations of the environment. In this paper we studied the root meristem mitosis Allium cepa L. During the laboratory experiment recorded the frequency of abnormal and normal mitosis in cells of the root meristem of onion (Allium cepa L.), treated with extracts of different concentrations (0.5%, 1%, 5.0 %) Plantago major L. i Plantago media L., growing in anthropogenic areas of Tobolsk.
