Answer 2

Animals are divided into different groups based on their complexity of the body structure:

PORIFERA

• The phylum consists of simple organisms commonly known as sponges.
• Sponges live in contact with water to facilitate the process of respiration, digestion, and excretion.
• The sponges are characterized by the presence of collar cells or choanocyte cells.
• These cells play important role in the movement of water through the sponge body.
• Examples - Bath sponge, Spongilla, Sycon.

CNIDARIA

• Animals with simple body organization and radial symmetry.  
• Characterized by the presence of cnidocyte or stinging cells.
• These specialized cells contain nematocysts used to immobilize prey.
• Example - Sea anemones, Jelly fishes, Corals.

The analogy is - Collar cells: Bath sponge:: Cnidocytes: Sea anemones.
