(N/A) $1$. Homologous Organs: These organs have the same evolutionary origin and structural plan but may perform different functions. In both grapevines and pumpkins,the tendrils are modifications of the axillary buds (stem origin). Since they share the same origin,they are considered homologous.
$2$. Analogous Organs: These organs have different evolutionary origins but perform similar functions. In peas,the tendrils are modifications of leaves (leaf origin). Although they perform the same function of climbing as the stem tendrils of grapevines,their structural origin is different. Therefore,they are considered analogous.
$3$. Conclusion: Because grape and pumpkin tendrils share a common stem-based origin,they are homologous. Because grape tendrils (stem-based) and pea tendrils (leaf-based) share a common function but have different origins,they are analogous.
