Method of use of biotechnological research (for example, biologically active substances of higher aquatic plants) in teaching Biology

Abstract

The article gives an opportunity for students to practice theoretical knowledge obtained by integrating
biotechnological research into methods of teaching biology in higher education institutions. With the
help of biotechnological research, methods for conducting standard laboratory studies of pedagogical biology
in higher educational institutions are proposed. Laboratory classes are conducted efficiently, using
comprehensive technological methods, depending on the pedagogical skills of the teacher. Based on the
use of biotechnological research, biologically active substances from high-water plants were determined.
The subject of the study were aquatic plants Eichhornia crassipes, Pistia stratiotes, grown in a special
liquid medium, under the conditions of luministate. The amounts of biologically active substances from
aboveground and underground parts of aquatic plants were analyzed. Most of the biologically active

substances are alkaloids, amino acids, anthraquinones, proteins, carbohydrates, coumarins,, polysaccharides,
steroids, terpenes, phenolic acids and flavonoids. Methodical work is important in determining
the method of detecting biologically active substances in special experimental work and analyzing the
results obtained by developing research abilities of students.
Key words: Eichhornia crassipes, Pistia stratiotes aquatic plants, biologically active substances.
