On completion of this course, the students will be able to:

CO80: To execute and implement procedures leading to field study of a floristic rich area to observe and collect the plants from their natural habitats.

CO81: To analyse and remember the gross anatomical details of cells, tissues and various other organs of plants.

CO82: To distinguish plants based on their taxonomic and evolutionary variation in xylem and phloem.

CO83:  To explain and interpret the details of the components of shoot, root, and floral development.

CO84:  To demonstrate and execute the preparation of permanent slides like anther, male gametophyte, different types of ovules for a better insight.

CO85: To implement the procedure of preparation of a plant specimen from members of locally available dicotyledonous and monocotyledonous families to distinguish among them.

CO86: To understand the methods used for describing various specimens with preparation of keys up to generic level of locally available plants.

CO87: To demonstrate formulating of different media for tissue culture, isolation of protoplast and organogenesis.
