Answer 1

1) Tendrils in cucumber

In a cucumber plant, the axillary bud of stem gets modified into 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.


Final answer: Stem tendrils

2) Tendrils in pea

Peas have leaf tendrils that are modified terminal leaflets. Hence, the tendrils are leaf modifications and not stem modification.


Final answer: Leaf tendrils

3) Tendrils in pumpkins

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.


Final answer: Stem tendrils

4) Tendrils in grapevines

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.


Final answer: Stem tendrils

5) Tendrils in watermelons

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.


Final answer: Stem tendrils
