Question

describe any two underground modification of stem​

Answer 1

Answer:

Explanation:

Undersground stem

Underground stems are modified plant structures that derive from stem tissue but exist under the soil surface. They function as storage tissues for food and nutrients, propagation of new clones, and perennation. Types include bulbs, corms, rhizomes, stolons, spindle-shaped, and tubers.

Answer 2

Answer:

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.
