Homologous organs:
(i) They have same basic structural design.
(ii) They perform different functions.
(iii) Their appearances are different.
Analogous organs:
(i) They have different basic structural design.
(ii) They perform similar functions.
(iii) They have similar appearances.
Wings of a bird and wings of a bat are analogous organs as they have different basic structural design but have similar appearance and perform similar functions.
