Overview

The course “Plant Physiology” is a Core Course in Semester V of B.Sc. Botany under the Choice Based Credit System (CBSE). The course has been meticulously designed to acquaint and enlighten the students about key concepts regarding various functional aspects of plants and complement the understanding of different topics of Plant Physiology, with special focus on uptake and translocation of water and nutrients, physiology of flowering and the role of plant growth regulators and photoreceptors.The objectives of this course are to give the target students an understanding of:
  • Water Potential and its components, and how they drive the flow of water
  • How the ascent of sap occurs in xylem
  • Transpiration and mechanism of stomatal movement.
  • The importance of mineral nutrition especially the role and deficiency symptoms of essential elements
  • How nutrients are uptaken and transported across cell membranes through active and passive processes
  • How translocation in the phloem occurs and its dependency on phloem loading and unloading
  • Discovery, chemical nature and physiological roles of plant growth regulators and some photoreceptors
  • Physiology of flowering with special focus on photoperiodism and vernalization
  • Seed dormancy
  • Growth and development
  • Stress Physiology
