Explain the terms analogous and

solution:
Homologous organs are those organs having similar basic structure but has been modified to perform different functions, e.g., forelimbs of reptiles, frog, lizard, bird and human (amphibians and mammals) are homologous organs. Such homologous characteristic helps to identify an evolutionary relationship between apparently different species.

Analogous organs are those organs which are different in basic structure but perform same function, e.g., wings of bat and wings of birds.
