Tendrils of grapevines are homologous to the tendrils of pumpkins but are analogous to that of a pea. Justify the above statement.

Answers (1)

Homologous organs have similar origins but different functions. The Tendril of grapevine is homologous to the tendril of pumpkin as both originate from the axillary bud of the stem but perform different functions. A tendril of grapevine helps in climbing, whereas a tendril of pumpkin helps in protection and anchoring. 

Analogous organs have different origins but the same function. The Tendril of the grapevine is analogous to the tendril of the pea as both perform the same function of climbing, but the tendril of the grapevine originates from the axillary bud of the stem, whereas the pea has a leaf tendril.
