Diversity And  Evolution Of Non-Chordates Practical

CO:31 Analyze anatomical features of various invertebrate specimens, including Annelids, Arthropods, Molluscs, and Echinoderms.

CO:32 Examine ecological roles of various invertebrate specimens, including Annelids, Arthropods, Molluscs, and Echinoderms.

CO:33 Investigate earthworm's digestive system and nephridia, understanding their functions in digestion and excretion.Examine transverse sections of earthworm's pharynx, gizzard, and intestine, understanding their adaptations for feeding and digestion.

CO:34 Create a project report on larval forms of crustaceans, molluscs, and echinoderms, demonstrating understanding of developmental biology and ecological roles.

CO:35 Demonstrate skills and record the concepts in the form of  practical file and reflect on personal learning experiences and experimental outcomes during viva voce.
