STRUCTURAL ADAPTATIONS OF CELLULAR WALLS OF AQUATIC PLANTS TO THE ACTION OF IONS OF ZINC AND LEAD

Main specific and nonspecific cells responses and membrane structures participation in formation of cells resistance in stress conditions, caused by heavy metals (chlorella, waterweed, duckweed) in toxic concentrations are analyzed. The cell membranes participation in adaptation to toxicants (formation of growths, multiplication, fluidization, forming of aquaporin, apoptosis), which are first exposed to stressors, is discussed. Found specific and nonspecific reactions in membrane formation are proposed to use as biomarkers of toxicity.
