Example of Porifera

Example of Porifera

• A. Sponges
• B. Jellyfish
• C. Clams
• D. Earthworms

Answer: (A)

Porifera are sponges, the simplest animals known for their porous bodies and cellular-level organization rather than true tissues or organs. They filter feed by pulling water through numerous pores into a central cavity and out through an opening, using specialized cells called choanocytes to capture food. This basic, tissue-less structure is the hallmark of Porifera. The other options belong to different animal groups with tissues and organs: jellyfish are cnidarians with tissues and a nerve net, clams are mollusks with a mantle and shell, and earthworms are annelids with segmented bodies and a digestive tract. So the example that fits Porifera is sponges.
