Which of the following openings have cilia?
Correct answer: A. Nephrostome
- A. Nephrostome
- B. Nephridiopore
- C. Both of these
- D. None of these
Explanation
The nephrostome of an earthworm has cilia that create a current and draw coelomic fluid into the nephridium. The nephridiopore is an external outlet and is not the ciliated funnel, so choosing both confuses the two openings.
