Tendrils of grapevines are homologous to the tendril of pumpkins but are analogous to that of pea. Justify the above statement.
Both the tendrils of grapevine are homologous to the tendril of pumpkin are modified stem that is they have a common origin but perform different functions. Thus they are homologous to each other.
However, the tendrils of pea are the modification of leaves but perform the same function as the tendrils of the grapevine and thus are called analogous organs.
