Question

Describe the different methods of asexual reproduction, giving examples and diagrams.

Accepted Answer

The process of production of new organisms from existing organisms is known as reproduction. It is of two types: Sexual reproduction and asexual reproduction. In asexual reproduction, new individuals are produced by a single parent, and there is no formation of gametes. Different methods of asexual reproduction are as follows:

Budding

Fragmentation

Spore formation

Vegetative propagation.

Budding: It is a type of asexual reproduction in which a small bud originates on the parent body. It grows detaches itself from the parent body and forms a new organism. For e.g., Yeast.

Fragmentation: It is a type of asexual reproduction in which an organism such as Spirogyra (algae) divides into multiple fragments. Each of these fragments or pieces grow into new organisms.

Spore formation: Ferns, mosses and many fungi (the bread mould) reproduce through spore formation. Spores are very small (microscopic) bodies having thick protective walls. These spores form new organisms when provided with favourable conditions.

Vegetative propagation: When new plants can be obtained from roots, stems, leaves or buds without the help of any reproductive organs, it is called vegetative propagation. There are two methods of vegetative propagation: Natural method and Artificial method.

1. Natural method of vegetative propagation:

Vegetative propagation by roots- For e.g. sweet potato, dahlia and asparagus.

Vegetative propagation by stems- For e.g., potato, ginger, turmeric etc.

Vegetative propagation by leaves- For e.g., Bryophyllum and begonia.

2. Artificial methods of vegetative propagation:

Vegetative propagation carried out manually is called artificial propagation. Stem cutting, layering and grafting are the artificial methods.
