Certain plants that reproduce asexually send out underground stems known as?

• A. Rhyizomes
• B. Root buds
• C. Stolons
• D. Suckers

Answer: (A)

Asexual reproduction in plants often uses underground stems that spread horizontally and store nutrients, helping the plant colonize nearby space and survive tough conditions. This underground system is called a rhizome. From the rhizome, new shoots can emerge at nodes, giving rise to genetically identical plants without seeds. That’s why rhizomes are a classic method of vegetative propagation.

Stolons, by contrast, are similar structures but lie above the ground and run along the surface, rooting at intervals to form new plants (like strawberry runners). Suckers are shoots that spring up from the base or roots of a plant, not from an underground stem, so they don’t fit the description of underground stems used for propagation. Root buds are not the standard term for this underground-reproducing system.

So the term that describes underground stems used for asexual propagation is rhizomes.
