Objective: 

This course will enable the students to-

  1. To study the vital and the various metabolic activities in plants.
  2. To provide an overview of the plant biochemical and physiological processes that could be exploited both to reduce the environmental impact of modern agricultural practices and to develop strategies and tools to increase plant yield and quality and to illustrates knowledge of stress adaptations in biological systems.
