Question

what is the distinguishing feature of sponges (phylum porifera) that sets them apart from many other multicellular organisms? they are only found on land. they lack true tissues. they have segmented bodies.

Explanation:

• Analyze the first option: Sponges (Porifera) are aquatic organisms, not only found on land, so this option is incorrect.
• Analyze the second option: Sponges are multicellular but lack true tissues (groups of specialized cells working together as a unit), which is a key distinguishing feature from many other multicellular organisms with true tissues.
• Analyze the third option: Segmented bodies are a feature of organisms like annelids, not sponges, so this option is incorrect.

Answer:

B. They lack true tissues.
