How does a runner function in asexual reproduction?
Understand the Problem
The question is asking about the role of a runner in the process of asexual reproduction, specifically what function it serves in generating new plants.
Answer
Runners facilitate asexual reproduction by forming new plants at nodes along the stem.
Runners, or stolons, are specialized horizontal stems that enable asexual reproduction in plants by forming adventitious roots and buds at nodes, which grow into new plants identical to the parent.

More Information
Runners are an efficient means for plants to expand and cover ground quickly, especially in favorable environments. This method ensures offspring are genetically identical to the parent, maintaining successful genetic traits.
Tips
A common mistake is confusing runners with rhizomes; while both are involved in vegetative propagation, rhizomes grow underground, whereas runners grow above the ground. Understanding the growth direction helps in distinguishing them.
