Bot.415 Advances in Plant Physiology 3+1

LEARNING OBJECTIVE:

 The study will provide depth understanding about Water relations of plants, Inorganic
nutrition, Photosynthesis, Respiration, Nitrogen metabolism, and Phytohormones.
 It will help to add about Growth, Stress physiology, and the coordination growth under
stress condition.

LEARNING OUTCOME:

 The students will be learning about the various mechanisms water and nutrient uptake in
plants.
 During the course students will strengthen their knowledge about photosynthetic pigments,
carotenoids, photosystems, oxygen evolving complex, and electron carriers.
 The course will deal with various phytohormones and their signalling pathways associated
with growth and development.
