a. Cucumber – Stem tendrils (In a cucumber plant, the axillary bud of the stem gets modified into a tendril. Hence, the tendrils in cucumber is a leaf modification. These slender, spiral, green, thread-like structures have adhesive glands for fixation and help in climbing onto a support).

b. Peas – Leaf tendrils (Peas have leaf tendrils that are modified terminal leaflets. Hence, the tendrils are leaf modifications and not stem modifications).

c. Pumpkins – stem tendrils (In pumpkins, the axillary bud is modified to form slender, spiral, green, thread-like structures with adhesive glands for fixation. These modifications are stem tendrils and help in creeping onto the ground).

d. Grapevines – stem tendrils (In grapevines, the axillary bud is modified to form slender, spiral, green, thread-like structures with adhesive glands for fixation. These modifications are stem tendrils found in weak stems and help them to climb onto a support).

e. Watermelons – stem tendrils (Watermelons have their axillary buds modified to form slender, spiral, green, thread-like structures. These help in creeping on the surface of a support and have adhesive properties for fixation on the support).
