Which one of the following pairs of items correctly belongs to the category of organs mentioned against itA. Thom of Bougainvillea and tendrils of Cucurbita-Analogous organsB. Nictitating membrane and blind spot in human eye-Vestigial organsC. Nephridia of earthworm and Malpighian tubules of cockroach - Exctretory organsD. Wings of honey bee and wings of crow - Homologous organs |
Answer» Correct Answer - C In annelids like Nereis, earthworm leech, etc., the tubber coiled structures called nephridia are excretory organs. In phylum-Arthropoda, insects centipedes, milipedes and arachnides possess Malpighian tubules as their principal excretory organ. Analogous organs have almost similar appearance and perform the same function but develop in totally different groups and are totally different in their basic structure and developmental origin, e.g., wings of butterfly, birds bats. The homologous organs have common origin, perform different type of functions and have different appearance, e.g., thorns of Bougainvillea and tendrils of Cucurbita. Vestigial organs are useless remnants which might have been large and functional in the anogestros e.g, nictitating membrane, vermiform apperdix, etc. |
