Solution

Asexual reproduction is the process by which a plant gives rise to a new plant without producing seeds or spores. Asexual reproduction in plants occurs by vegetative propogation. The development of a new plant from the vegetative part of a plant-like stem, root, or leaf is known as vegetative propogation. The various methods of vegetative propogation are:
From underground stem: A potato plant has an underground stem known as the tuber. It has many buds called eyes. A vegetative bud consists of a short stem, around which immature overlapping leaves are present in a folded state. A bud can give rise to a new plant through asexual reproduction.
Rhizome: The underground stem of ginger is known as the rhizome which is capable of giving rise to a new plant. A corm is the underground stem as found in Gladiolus. It can also be used for vegetative propogation.

Through leaves: Leaves perform the function of photosynthesis. However, they can take part in asexual reproduction as well. In some plants, leaves can give rise to a new plant asexually. For example, the leaves of the plant Bryophyllum contain buds on its margins. These buds give rise to a new plant through asexual reproduction.

From aerial stem: In certain plants, a slender stem arises from the base of the plant and touches the soil, it develops roots and buds at the point of contact with the soil and gives rise to new plants. When the new plant is old enough the stem connecting it to the parent plant withers away.
