Question

Organs that have different embryonic origin but perform similar functions are:

• A. Homologous organs
• B. Analogous organs
• C. Vestigial organs
• D. Identical organs

Answer 1

Answer: (B)

Analogous organs

Organisms belonging to different groups but living in the same habitat have organs that are modified and adapted to their requirements. This gives rise to organs that may have a different origin with dissimilar structures but will perform similar functions. These types of structures or organs are called analogous organs. For example, the wings of a bat and an insect. Bats and insects have different embryonic origins; bat is a mammal whereas, an insect is an arthropod. Their wings are structurally different. The wings of bats have bones but, insects' wings are membranous folds composed of cuticle. But both these types of wings perform a similar function, i.e. of flying.

Hence, option B is the correct answer.
