Question

give examples of leaf tendrils and leaf spine​

Answer 1

Common examples of tendril-producing plants are the grape, members of the squash or melon family (Cucurbitaceae), the sweet pea (Lathyrus odoratus), and the passionflowers (Passiflora species).

Two examples of true spines (modified leaves). Left: Barberry (Berberis vulgaris) showing lateral buds arising in the axils of 3-pronged, modified leaves called spines. Right: Gum tragacanth, an Iranian locoweed (Astragalus), showing the rigid, sharp-pointed leaf rachises after the leaflets have dropped off.
