Step-by-Step Solution

According to the text:

  • Scales: Reptiles (Class Reptilia) are characterised by the presence of dry and cornified skin, epidermal scales or scutes.
  • Comb plates: Ctenophores (Phylum Ctenophora) bear eight external rows of ciliated comb plates, which help in locomotion.
  • Radula: The mouth of Molluscs (Phylum Mollusca) contains a file-like rasping organ for feeding called radula.
  • Choanocytes: Sponges (Phylum Porifera) have choanocytes or collar cells lining the spongocoel and canals.
