Sycon belongs to a group of animals, which are best described as

  1. unicellular or acellular
  2. multicellular without any tissue organization
  3. multicellular with a gastrovascular system
  4. multicellular having tissue organization, but no body cavity.

Answer

(2) multicellular without any tissue organization

Solution

Sycon (Scypha) is a sponge — Phylum Porifera.

As per NCERT, members of Phylum Porifera are multicellular animals with a cellular level of organisation; true tissues are absent.

∵ A gastrovascular cavity is found in coelenterates, and tissue level without a body cavity in coelenterates / flatworms.

∴ Sycon is multicellular without any tissue organisation.
