BIOLOGY AND PLANT PHYSIOLOGY
Learning outcomes of the course unit
To provide the student with elementary knowledge relating to the nature of the living matter and plant organisms; the fondamental physiology, anatomy and morphology of the organisms, and their genetics, with special reference to those organisms that represent a source of food for man.
