Question

Shashwat identified a new organism X. After carefully examining he observed that X resembles Hydra.

Identify from the following which characters of X justify it's resemblance with Hydra.

• A. Aquatic habitat
• B. Lives in colonies
• C. Solitary
• D. Having tentacles

Answer 1

Answer: (A), (C), (D)

The correct options are
A Aquatic habitat
C Solitary
D Having tentacles

Hydra belongs to phylum Coelenterata. It is an aquatic animal, present in freshwater. These organisms stay solitary, rather than in colonies (e.g., corals). The organisms belonging to phylum Coelenterata bear tentacles on their body. These tentacles contain cnidoblasts or cnidocytes (stinging cells). Since, X resembles Hydra, then it should have these characters.
