Question

Which one of the following groups are not analogous organs?

• A. Wings of birds and wings of butterfly
• B. Eye of octopus and eye of mammals
• C. Flippers of penguin and flippers of dolphin
• D. Thorns of bougainvilla and tendril of Cucurbita
• E. Tuberous root of sweet potato and tuberous root of carrot

Answer 1

Answer: (D)

Thorns of bougainvilla and tendril of Cucurbita

Analogous structures/organs are ones that basically have the same function but not the same underlying structures/organs. Thorns of bougainvilla and tendril of Cucurbita do not have the same function and thus, could not be called as analogous organs.
