Course Objectives
• Describe how physiological processes scale up from the functioning of complex structures such as stems, roots and leaves to whole plants and plant communities
• Our objective is to provide training in scientific and transferable skills through modular lecture courses, research projects, written work, seminars and supervisions.

Course Syllabus
Module-I
Plant-water relations: Water Potential and its components, water absorption by roots, aquaporins, pathway of water movement,symplast, apoplast, transmembrane pathways, root pressure, guttation.
Practice:
1. Determination of osmotic potential of plant cell sap by plasmolytic method.
2. Determination of water potential of given tissue (potato tuber) by weight method.
Module-II
Ascent of sap: Cohesion-tension Theory; Transpiration and factors affecting transpiration, antitranspirants, mechanism of stomatal movement; Minerals: Mineral nutrition; . Macro and micronutrient; Essential and beneficial elements, methods of study and use of nutrient solutions; criteria for essentiality, mineral deficiency symptoms and their solution, roles of essential elements, chelating agents.
Practice:
1. Study of the effect of wind velocity and light on the rate of transpiration in excised twig/leaf.
2. Calculation of stomatal index and stomatal frequency from the two surfaces of leaves of a mesophyteand xerophyte.
3. To calculate the area of an open stoma and percentage of leaf area open through stomata in a mesophyte and xerophyte (both surfaces).
4. To demonstrate suction due to transpiration
Module-III
Nutrient Uptake: Soil as a nutrient reservoir, transport of ions across cell membrane, passive absorption, electrochemical gradient, facilitated diffusion, active absorption, role of ATP, carrier systems.
Module-IV
Translocation in The Phloem: Experimental evidence in support of phloem as the site of sugar translocation, Pressure–Flow Model; Phloem loading and unloading, Source–sink relationship.
Practice:1. Study of water absorption through root.
Module-V
Plant Growth Regulator: Discovery, chemical nature (basicstructure), bioassay and physiological role of Auxin, Gibberellins, Cytokinin, Abscisic acid, Ethylene, Brassino steroids and Jasmonic acid.
Practice:
1. To study different concentration on Avenacoleoptile elongation (IAA Bioassay).
2. Bolting experiment/Avenacoleptile bioassay (demonstration)
Module-VI
Stress Physiolology: Abiotic stress on plant; drought, salinity, cold, heat, submergence etc. Biotic stress on plant.
Module-VII
Physiology of Flowering: Photoperiodism, flowering stimulus, florigen concept, vernalization, seed dormancy. Phytochrome, Crytochromes and Phototropins: Discovery, chemical nature, role in photo morphogenesis, low energy responses (LER) and high irradiance responses (HIR),mode of action.
