Differentiate between homologous organs and analogous organs?  

1 Answer

Answer :

Homologous organs: -

Organs, which do not look alike but their internal structure is almost similar. E.g. fore

limbs of horse, human arm, wing of bird etc

Analogous organs: -

Organs, which are similar in function but different in basic structure. E.g. wing of fly

bird performs same function but their structure is different.
