Kostyuk K. Structural and functional response of water plant cells to the action of toxicants

This thesis is devoted to research of influence of different toxicants (Zn2+ - 1,0 mg/l; 2,0 и 5,0 mg/l; Pb2+ - 0,1 mg/l; 0,2 и 0,5 mg/l; diesel fuel - 0,01 ml; 0,05; 0,1; 0,2; 0,3 ml) on the structural and functional changes of cell and cellular membranes of water plants (Chlorella vulgaris Beijer., Elodea canadensis Michx., Lemna minor L.). Membranogenesis, qualitative and quantitative composition of cell membranes of water plants were investigated. It has been shown for the first time that the mechanism of adaptation of water plants to chemicals through induction of their cells of double concentric membranes, detected changes in lipid and protein composition, permeability and activity of membranes ATP-ase and alkaline phosphates in the process of their formation.
