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
