Question

Explain asexual reproduction in plants.

Answer 1

Asexual reproduction in plants is the process by which a new plant is produced from a single parent without the formation and fusion of gametes. In plants, it commonly occurs through vegetative propagation, in which new plants develop from vegetative parts such as roots, stems, or leaves. Methods of vegetative propagation are:

1. From the underground stem
   • The potato plant has an underground stem called a tuber.
   • It bears buds called eyes, which can develop into new plants.
   • Similarly, the rhizome of ginger and the corm of Gladiolus can also give rise to new plants.
2. Through leaves
   • In some plants, leaves produce buds that develop into new plants.
   • For example, Bryophyllum has buds along the leaf margins that grow into new plants.
3. From the aerial stem
   • In plants such as strawberries, a slender stem grows along the ground.
   • When it touches the soil, roots and buds develop at the nodes, forming new plants.
   • Later, the connection with the parent plant dries up.

Answer 2

1. Asexual reproduction in plants is the process by which new plants are produced from a single parent without the formation and fusion of gametes. One common method of asexual reproduction in plants is vegetative propagation.
2. In vegetative propagation, new plants are produced from vegetative parts such as roots, stems, leaves, and buds.
3. All plants produced by this method are genetically similar to the parent plant because they arise from a single parent. For examples:
   • Potatoes reproduce through buds present in the eyes of the tuber.
   • Bryophyllum reproduces through buds present on the leaf margins.
   • Sugarcane and grasses reproduce through buds present at the nodes.
   • Carrots and radishes can reproduce with the help of the root.
