Question

Scales of fish and shells of molluscs are homologous or analogous organs

Answer 1

They are analogous organs since their origin and basic structure is different but their function is same (of protection)

Answer 2

Analogous organs

Explanation:

• The analogous organs are those organs which functionally similar in organisms but structurally different.
• As these organs are different in structure thus no ancestral origin can be traced back.
• An example is wings of insects, bats and birds as these structures evolved independently from different lineages.
• The scales of fish and shells of molluscs are structurally different. Thus no phylogenetic or ancestral relationship can be traced back but these are functionally similar that is the scales and shells helps in providing protection against the predator.
