Which one of the following phyla is correctly matched with its two general characteristics?

  1. Echinodermata - pentamerous radial symmetry and mostly internal fertilization
  2. Mollusca - normally oviparous and development through a trochophore or veliger larva
  3. Arthropoda - body divided into head, thorax and abdomen and respiration by tracheae
  4. Chordata - notochord at some stage and separate anal and urinary openings to the outside

Answer

(3) Arthropoda - body divided into head, thorax and abdomen and respiration by tracheae

Solution

As per NCERT, the body of arthropods consists of head, thorax and abdomen, and respiratory organs include the tracheal system (besides gills, book gills and book lungs). Hence (3) is correct.

⇒ As per NCERT, echinoderms show radial (pentamerous) symmetry in adults, but fertilisation is usually external, so (1) is wrong.

⇒ Molluscs are usually oviparous with indirect development, but a trochophore or veliger larva is not a general feature of the whole phylum, so (2) is not the best match.

⇒ Chordates have a notochord at some stage, but many (amphibians, reptiles, birds) have a common cloacal opening, so (4) is wrong.

Answer: (3)
