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 Invertebrate s |
CO120: Able to explain the basis of classification in Invertebrates CO121: Judge the structur e and physiological functions of Invertebrates C0122: Understand the evolutionary advancement of digestion, locomotion, respiration, nervous and excretory functions in different invertebrate phylums. CO123: Illustrate the significance of Larval forms of invertebrates and can correlate their characteristic features with their adult forms. CO124: Correlate the characteristics, features and significance of Minor Phyla; as well as their role in the ecosystem CO125: Contribute effectively in course-specific interaction |
Approach in teaching: Discussion, Demonstration, Field Trip Learning activities for the students: Field activities, Simulation, Presentation, Giving task |
Class test Semester end examinations, Quiz, Assignments, Seminar Presentation Individual and group projects |
Basis of classification (brief account)-:
Symmetry, coelom, segmentation, embryogeny and level of organization
Locomotion-:
Flagellar and ciliary movement in protozoa
Hydrostatic movement in Coelenterate, Annelida and Echinodermata
Nutrition and digestion
Filter feeding in Polychaeta, Mollusca and Echinodermata Respiration
Organs of respiration – gills, lungs and trachea Respiratory Pigments
Mechanism of respiration
Excretion
Organs of excretion: coelom, coelomoducts, nephridia and Malpighian Tubules Mechanism of excretion Excretion and osmoregulation
Trends in Neural Evolution
Primitive nervous system -Coelenterata and Echinodermata
Advanced nervous system- Annelida, Arthropoda (Crustacean and Insecta) and Mollusca (Cephalopoda)
Larval forms of free living invertebrates
Larval forms of parasites
Significance of larval forms
