Objective: 
  1. To impart knowledge about not only morphology, structure and development of flowering plants but also at their practical and experimental aspects as they are most sought after areas of modern research.
  2. To enhance the fundamental knowledge about living cells and their systematic up gradation in to the tissue level.
  3. To study the differentiation features of internal structure of the plant body.
  4. To obtain a thorough knowledge about the life cycle of higher plants and study special phenomena related to their development.

Developmental and Reproductive Biology of Angiosperms

 

CO77:  Maximize their knowledge about histological organization of root & shoot meristems and their secondary structures

CO78:  Understand the structural details and development of leaf and flower to build the concept of genetic and molecular aspects of their development.

CO79:  Determine the structure & development of male and female gametophyte and vital plant processes like fertilization and pollination.

CO80:  Propose solutions to problems of self-incompatibility faced by the geneticists and plant breeders by understanding various stages of plant development.

CO81:  Evaluate the causes of polyembryony, apomixes, and plan culture experiments related to embryo, nucellus and ovules.

CO82: Contribute effectively in course-specific interaction.
