Question

33. Explain the modifications seen in stems with example.
bulum

Answer 1

Answer:

Tendrils are slender, twining strands that enable a plant (like the buckwheat vine) to seek support by climbing on other surfaces. ...

Answer 2

Explanation:

Modified stems that grow horizontally underground are either rhizomes, from which vertical shoots grow, or fleshier, food-storing corms.

New plants can arise from the nodes of stolons and runners (an aboveground stolon): stems that run parallel to the ground, or just below the surface.

Potatoes are examples of tubers: the swollen ends of stolons that may store starch.

The stem modification that has enlarged fleshy leaves emerging from the stem or surrounding the base of the stem is called a bulb; it is also used to store food.

Aerial modifications of stems include tendrils, thorns, bulbils, and cladodes
