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.
