Plant Physiology and Metabolism

By Dr. Sudeshna Shyam Choudhury   |   St. Xavier’s College, Kolkata
The course focuses on the fundamentals of plant physiology for undergraduate students. It consists of 40 modules divided into nine major units. This course will acquaint students with the basic concept of plant water relation and mineral nutrition. This course will help them to understand the different physiological processes of translocation, photosynthesis, respiration and nitrogen metabolism. Within respiration they will learn different basic metabolic processes. They will also learn about structure, function, nomenclature, assay of different enzymes and plant growth regulators specially hormones. They will have an idea of differential plant response to light and temperature.
Thus by studying these 40 modules, a student should be able to understand and appreciate the major concept of plant physiology including the different catabolic and anabolic processes, mineral nutrition, enzymes, plant growth regulation, photoperiodism and vernalization.
