Choanoflagellates resemble to collar cells in
Correct answer: A. Sponges
- A. Sponges
- B. Cnidarians
- C. Ciliates
- D. Actinopods
Explanation
Choanoflagellates are single-celled organisms that have a distinctive structure featuring a collar of microvilli surrounding a single flagellum. This structure is remarkably similar to the choanocytes (collar cells) found in sponges, which also use a similar mechanism to filter food particles from the water. This similarity suggests a close evolutionary relationship between choanoflagellates and sponges. The other options, such as cnidarians, ciliates, and actinopods, do not share this specific cellular structure.
