Question

Which of the following groups consists of analogous organs?

• A. Nephridia, Malpighian tubules, Keber's organ
• B. Ctenidia, Taenidia, Comb plates
• C. Flame cells, Oxyntic cells, Peptic cells
• D. Amphids, Statocyst, Halteres

Hint:

Analogous = Same Function, Different Origin (e.g., Excretion in different animals).

Answer 1

The Correct Option is A

Step 1: Concept
Analogous organs are structures that have different evolutionary origins and internal anatomy but perform similar functions (Convergent Evolution).

Step 2: Meaning
Nephridia (Annelids), Malpighian tubules (Insects), and Keber's organ (Mollusks) all serve as excretory organs in their respective phyla.

Step 3: Analysis
While they all perform the same function of waste removal, they are anatomically distinct and evolved independently across different invertebrate groups.

Step 4: Conclusion
Group A represents analogous structures centered on excretion. Final Answer: (A)
