Objective: 

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 (Theory)

CO13: Explain the    basis of

classification in

Invertebrates and locomotion in

invertebrates

CO14:Judge the structure  and

physiology  of  Digestive  and

Respiratory       System        of

Invertebrates

CO15:Understand              the

evolutionary  advancement of

nervous and excretory functions

in       different          invertebrate phylums.

CO16:Illustrate the

significance of Larval forms of

invertebrates and can correlate

their characteristic features with

their adult forms.

characteristics,    features    and

significance of Minor Phyla; as

well    as    their    role    in    the

ecosystem

CO18:Contribute effectively in

course-specific interaction
