Chordate vs Non-Chordate Features — NEET Biology
📚 Practice ConceptTable 4.1 presents a comparison of salient features of chordates and non-chordates.
Which of the following statements are correct regarding the classification and features of various animal phyla? S1: Coelenterates are diploblastic and radially symmetrical, while Platyhelminthes are triploblastic and bilaterally symmetrical. S2: Both Aschelminthes and Platyhelminthes are acoelomate, with organ-system level of organisation. S3: Bioluminescence is a distinctive property of Ctenophores, and they possess eight external rows of ciliated comb plates for locomotion. S4: Annelids, Arthropods, and Molluscs all exhibit metameric segmentation and organ-system level of organisation. S5: While Echinodermata are triploblastic and coelomate, their adult forms show radial symmetry, unlike their larvae.
