Asexual Reproduction in Plants
Plants can clone themselves.
About this topic
Many plants reproduce asexually, producing genetically identical clones from one parent without seeds. Methods include runners (strawberries), bulbs (daffodils), tubers (potatoes), rhizomes (ginger), and plantlets. Gardeners use cuttings, grafting and layering. In tissue culture, small pieces are grown on nutrient agar to make thousands of identical plants.
Advantages: fast, reliable, no pollinator needed. The disadvantage is a lack of variation, so a disease can wipe out the whole crop.
A spider plant sends out runners with plantlets that root and become new plants, and a potato tuber sprouts new shoots from its eyes. Gardeners take cuttings and use rooting hormone, and growers use tissue culture, growing tiny pieces of tissue in nutrient jelly to produce thousands of identical plants, used for orchids and bananas.
Advantages are speed and no need for a partner or pollinator; the disadvantage is no variation, so a disease can wipe out a whole crop of clones. Seedless bananas are all clones, and a fungus now threatens them. Students often think asexual reproduction means no seeds in any case; some plants, such as dandelions, can make seeds asexually. Compare with sexual reproduction, which creates variation through mixing of gametes.
