Which term describes a stem that creeps across the soil, grows roots and develops into a replica plant?

• A. Bulblet
• B. Plant runners
• C. Cormel
• D. Chlorosis

Answer: (B)

Plant runners are horizontal stems that creep along the soil surface and root at intervals to produce new, genetically identical plants. This growth habit lets a single plant clone itself and spread quickly, which matches the description of a stem that travels across the ground, takes root, and becomes a replica plant. The other terms refer to different forms of propagation or to a symptom: a bulblet is a small bulb used for new plants, a cormel is a tiny corm for propagation, and chlorosis is a yellowing condition of leaves, not a propagative stem.
