Phylum Characteristics & Key Features — NEET Biology
📚 Practice ConceptAnnelids are metamerically segmented animals with a true coelom. The arthropods are the most abundant group of animals characterised by the presence of jointed appendages. The molluscs have a soft body surrounded by an external calcareous shell. The body is covered with external skeleton made of chitin. The echinoderms possess a spiny skin. Their most distinctive feature is the presence of water vascular system. The hemichordates are a small group of worm-like marine animals. They have a cylindrical body with proboscis, collar and trunk.
Match the organisms in Column I with their specific structures/functions in Column II. COLUMN I (ORGANISMS) 1. Asterias 2. Prawn 3. Sycon 4. Earthworm 5. Cockroach COLUMN II (CHARACTERISTICS) a) Nephridia for excretion b) Canal system for food gathering and respiration c) Malpighian tubules for excretion d) Water vascular system for locomotion and respiration e) Green glands for excretion
View solution & NCERT explanation
Correct answer: C — 1-d, 2-e, 3-b, 4-a, 5-c
Asterias (Starfish, Echinodermata) → Water vascular system (d). Prawn (Crustacean, Arthropoda) → Green glands for excretion (e). Sycon (Porifera) → Canal system (b). Earthworm (Annelida) → Nephridia for excretion (a). Cockroach (Insect, Arthropoda) → Malpighian tubules for excretion (c). Thus, the correct combination is option (c).
