Question
Which one of the following pair of items correctly belongs to the category of organs mentioned against it?
Thorn of Bougainvillea and tendrils of Cucurbita – Analogous organs
Nictitating membrane and blind spot in the human eye – vestigial organs
Nephridia of the earthworm and Malpighian tubules of cockroach - Excretory organs
Wings of a honey bee and wings of crow - Homologous organs
Nephridia are the tubular excretory structures of earthworms (annelids) , and Malpighian tubules are the excretory structures of insects like cockroaches ; therefore, this pair is correctly matched. In contrast, the thorns of Bougainvillea and tendrils of Cucurbita are homologous organs (divergent evolution) , and the wings of insects (honey bee) and birds (crow) are analogous organs (convergent evolution) .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Evolution. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
