प्रश्न
Tendrils of grapevines are homologous to the tendril of pumpkins but are analogous to that of pea. Justify the above statement.
उत्तर
Tendrils of grapevines are homologous to the tendril of pumpkins because both are the modification of the stem (i.e., stem tendrils). The homologous structure has the same origin.
The analogous structure has a different origin but similar function. Tendrils of grapevines are analogous to that of a pea because tendrils of grapevines are modifications of the stem while tendrils of pea are modifications of leaves. Both have different origins but perform the same function, i.e., support.
