Question

Which of the following is a pair of analogous organs?

• A. Contractile vacuole in $Amoeba$ and uriniferous tubule in frog
• B. Paddle of whale and front legs of horse
• C. Thorn of Bougainvillea and tendrils of Cucurbita
• D. Forelimbs in lizard and wings in birds

Answer 1

Answer: (A)

Contractile vacuole in Amoeba and uriniferous tubule in a frog are analogous organs. Analogous organs have different origins and structures but have the same function. Similarity on the basis of the same function is called an analogy. Both contractile vacuoles and uriniferous tubules are concerned with osmoregulation.
