ATendrils protect the plant from grazing animals
BThorns let the plant climb on other surfaces
CThorns store starch for the winter season
DTendrils let the plant climb on other surfaces
Answer & Solution
Correct answer: D. Tendrils let the plant climb on other surfaces
1. Tendrils and thorns are the two aerial stem modifications named for stems.
2. Tendrils are slender twining strands that let a plant seek support by climbing on other surfaces.
3. Thorns are modified branches that appear as sharp outgrowths and protect the plant.
4. Swapping the two roles produces the two wrong options, and starch storage belongs to tubers and corms.
