Detailed explanation-1: -II. Stem tendrils develop from axillary buds in plants like cucumber and they help in climbing.
Detailed explanation-2: -Complete answer: Watermelon, cucumber, and pumpkin have modified axillary buds that form thin, wiry, leafless, and spirally coiled branches and it helps the weak plant to climb the support referred to as stem tendrils.
Detailed explanation-3: -Stem tendrils develop from axillary buds. They are slender, spirally coiled and help plants climb up structures. They are seen in gourds (cucumber, pumpkins, watermelon) and grapevines.
Detailed explanation-4: -Solution : Grape Vine and Pumpkin have long slender and coiled stem tendrils.
Detailed explanation-5: -An axillary bud, the precursor of a branch or lateral shoot, is formed at the junction between a leaf and the stem. The shoot apex tends to inhibit outgrowth of axillary buds, a phenomenon called apical dominance. Removal of the shoot tip leads to growth of these buds to produce lateral shoots.
