Runners are specialized stems called stolons. These stems grow horizontally outward and downward from plants and produce baby plants at their tips. By cutting off the babies and planting them or allowing them to root on their own, additional plants may grow. This phenomenon is known as asexual reproduction.

What are runners in biology?
stolon, in biology, a special slender horizontal branch serving to propagate the organism. In botany a stolon—also called a runner—is a slender stem that grows horizontally along the ground, giving rise to roots and aerial (vertical) branches at specialized points called nodes.
What are runners give examples?
The runners also show the presence of some nodes that give rise to leaves and buds. The examples of runners are hydrocotyle plants, Oxalis, Cynodon dactylon that is also known as the lawn grass. Examples of suckers are mint also known as pudina, chrysanthemum, etc.
Which plant uses runners to reproduce asexually?
Natural Methods of Asexual Reproduction
In some plants, such as the sweet potato, adventitious roots or runners (stolons) can give rise to new plants. In Bryophyllum and kalanchoe, the leaves have small buds on their margins.
How do bulbs tubers and runners reproduce asexually?
Tubers, such as potatoes, are fleshy underground storage structures composed of enlarged parts of the stem. A tuber functions in asexual propagation as a result of the tiny scale leaves equipped with buds that grow on its surface. Each of these buds can form a new plant, genetically identical to the parent.
What is runners in plant propagation?
Runners. Also known as stolons, runners are modified stems that, unlike rhizomes, grow from existing stems just below the soil surface. As they are propagated, the buds on the modified stems produce roots and stems. Those buds are more separated than the ones found on the rhizome.
What is the function of runners in plants?
A runner is the stem portion of the plant that tends to grow horizontally as opposed to upright like the main stem. The end tip of the runner can produce buds that develop into new plants that are clones. Adventitious roots are also produced from the buds found on the runner.
What is a runner called?
Synonyms: athlete, miler, sprinter, harrier More Synonyms of runner.
Who is runner?
A runner is a person who runs, especially for sport or pleasure. ... a marathon runner. I am a very keen runner and am out training most days. Synonyms: athlete, miler, sprinter, harrier More Synonyms of runner.
What are runners of grass?
What Exactly Is a Runner? An aboveground runner, formally known as a stolon, is a stem or shoot of grass that grows upward, out of the crown of the grass plant. As it grows, it does what many landscaping enthusiasts refer to as creeping, which simply means it grows horizontally across the surface of the ground.
How do runners reproduce asexually?
Runners are specialized stems called stolons. These stems grow horizontally outward and downward from plants and produce baby plants at their tips. By cutting off the babies and planting them or allowing them to root on their own, additional plants may grow. This phenomenon is known as asexual reproduction.
How do bulbs reproduce asexually?
Bulbs enable plants to reproduce asexually—that is, without producing gametes. ... Eventually, gemmae grow into new gametophyte plants. Other plants reproduce asexually through the development of miniature plantlets at the edges of their leaves. In time these plantlets drop off and develop into independent plants.
Why asexual reproduction is important?
The advantages of asexual reproduction include: the population can increase rapidly when the conditions are favourable. it is more time and energy efficient as you don't need a mate. it is faster than sexual reproduction.
What triggers asexual reproduction?
Asexual reproduction occurs when an organism makes more of itself without exchanging genetic information with another organism through sex. ... This is beneficial to the population because genetically diverse populations have a higher chance of withstanding survival challenges such as disease and environmental changes.
How do plants reproduce asexually GCSE?
Plants reproduce sexually when a pollen grain from the male part of the flower fuses with the ovule from the female part of a flower. ... Some plants can reproduce asexually by growing runners. Gardeners may clone plants to produce a large number of genetically identical plants with desirable characteristics.
How do runners grow?
Most varieties of strawberries produce runners, also known as stolons. These runners will eventually develop their own roots, resulting in a clone plant. Once these adventitious roots establish in the soil, the runners begin to dry up and shrivel away.
