Dear student 
Homology : Those structure which have similar anatomy but perform different functions shows homology.
Example: Thorns of bougainvilleas and tendrils of cucurbits and forelimbs of whale and bats.
 
Analogy : Those structure which have similar functions but different anatomy shows analogy .
Example: Eye of octopus and mammals etc. Sweet potato and potato tuber.

Homology involves the study of organs that have evolved from same origin or from common ancestor but have different functions. For example, wings of bat and hands of humans. 
Analogy involves the study of organs that are evolved from different ancestors but perform a similar function.
For example, wings of bat and wings of insects.
