Certainly! Here's a breakdown of the descriptions provided:
1. Unicellular, has tissues, reproduces asexually:
- This description is incorrect because unicellular organisms do not have tissues. Tissues are a feature of multicellular organisms where specialized cells group together to perform specific functions.
2. Multicellular, no tissues or organ systems, reproduces asexually or sexually:
- This description is incorrect as well because multicellular organisms typically have tissues and organ systems. Organisms without tissues or organ systems are usually simple multicellular organisms like sponges.
3. Unicellular, marine, filter feeder:
- This description is correct. Sponges are multicellular but lack true tissues or organs. They are filter feeders that live in marine environments.
4. Multicellular, tissues regulate filter feeding:
- This description is incorrect because sponges do not have tissues that regulate filter feeding. Sponges filter feed by pumping water through their bodies and trapping food particles.
Therefore, the correct description of a sponge from the options provided is: "Unicellular, marine, filter feeder." This description accurately captures the key characteristics of sponges.
