Course objectives:

This course will enable the students to –

  1. Give an insight into the structure and mechanism of various life processes found in invertebrates.
  2. With the knowledge of basis of classification and detailed comparative study of the various physiological functions in an invertebrate body belonging to diverse phyla, students must be able to find affinities amongst each group
  3. The study on Minor phyla and the various larval forms will be adding value to their concepts.

Structure and Function of Invertebrates

 

Students will-

 

CO12: Able to explain the basis of classification, different physiological body processes of invertebrates.

 

CO13: Illustrate the significance of Larval forms of invertebrates and can correlate their characteristic features with their adult forms.

 

CO14: Correlate the characteristics, features and significance of Minor Phyla;  as well as their role in the ecosystem

 

CO 15: Judge the structure and metabolic functions of Invertebrates

 

CO16:Deduce the basis of classification

Approach in teaching: Discussion, Demonstration, Action Research, Project, Field Trip
