Is there a trick to remember Analogous and Homologous organs examples ?

Homologous organs :

Similar structure , different function, Developmental origin is same, Divergent evolution
 

Example :

  • Flipper - whale
  • Wing - bat
  • Fore limb -horse
  • Paw - cat
  • Hand - human
  • Thorn - bougainvillaea
  • Tendril - cucurbita
     

Analogous organ :

Same function , different structure. Convergent evolution. Not anatomically similar
 

Example :

  • Wings of a butterfly and wings of a bird.
  • Flippers of penguin and dolphin
  • Eye of an octopus and a mammal ( both differ in retinal position but function is same )
  • Sweet potato( root modification) and potato ( stem modification) - both help in storage of food.
