Question

Tendrils of Vitis (grapevine) are homologous to tendrils of Cucurbits but analogous to those of pea. Justify the above statement.

Answer 1

Homologous: Have a similar origin but different function

Tendrils of Vitis (grapevine) are homologous to tendrils of Cucurbita because they have the common origin as they both are modified stem but performs different functions.

Analogous: Have different origin and similar function.

Tendrils of Vitis (grapevine) are analogous of those of pea because tendrils of pea are the modification of leaves but perform the similar function as tendrils of grapevine, Hence analogous.
