Course Objectives: 

This course will enable the students to-

  1. To make the students study morphology, structure and development of flowering plants and its practical and experimental aspects.
  2. To make the students learn about the basic concepts in anatomy and to understand the various components of stem and wood during its secondary growth, about the mechanism of pollination and basic structure of the embryo.

Plant Anatomy and Embryology

CO51: The course paper cover basic aspects of anatomy of plant tissues such as meristems, epidermis, permanent tissues, complex tissue systems and structure of plant organs; reproductive developmental aspects of male reproductive system and female reproductive system.

CO52: Students will be able to utilize embryological studies in various aspects like analysis of evolutionary trends, circumscription and delimitation of taxa and making a decision on systematic positions.

CO53: Students will be able to analyze the composition of different parts of plants and their relationships
