Classification of Animal Phyla — NEET Biology
📚 Practice ConceptPorifera (b) Ctenophora (c) Echinodermata (d) Chordata
Match the following distinctive features with their respective phyla: Column I (Distinctive Feature) A. Comb plates B. Notochord C. Water canal system D. Flame cells E. Cnidoblasts Column II (Phylum) i. Chordata ii. Platyhelminthes iii. Ctenophora iv. Porifera v. Cnidaria
View solution & NCERT explanation
Correct answer: A — A-iii, B-i, C-iv, D-ii, E-v
This question tests the distinctive features of various animal phyla as given in NCERT. A. Comb plates are the eight external rows of ciliated plates characteristic of Phylum Ctenophora, used for locomotion (NCERT page 42). B. Notochord is a mesodermally derived rod-like structure found in Phylum Chordata during embryonic development (NCERT page 39). C. Water canal system is a characteristic feature of Phylum Porifera, helping in food gathering, respiratory exchange, and waste removal (NCERT page 40). D. Flame cells are specialized cells in Phylum Platyhelminthes that help in osmoregulation and excretion (NCERT page 42). E. Cnidoblasts (or cnidocytes) containing stinging capsules are present in Phylum Cnidaria, used for anchorage, defense, and prey capture (NCERT page 41). Thus, the correct match is A-iii, B-i, C-iv, D-ii, E-v.
