Q
Reproduction in Plants

Question:

Describe the different methods of asexual reproduction. Give examples.

Answer:

In asexual reproduction, plants can give rise to new plants without seeds. Asexual reproduction in plants can take place by the following methods:

1. Vegetative propagation:  Vegetative propagation is a type of asexual reproduction in which new plants are produced from roots, stems, leaves, and buds. 

  • Vegetative propagation by stems – Example: rose, Champa, money plant, and sugarcane.
  • Vegetative propagation by roots – Example: Dahlia and sweet potato
  • Vegetative propagation by leaves – Example: Bryophyllum

2. Buddig: In budding, a small part of the body of the plant grows out as a bulb-like projection called ‘bud’ which gradually grows and detached from the parent body and forms a new plant. Eg: Yeast

3. Fragmentation: Fragmentation is the method in which the body of a plant is broken into two pieces on maturing and each part grows to form a new plant. Example: Spirogyra (algae).

4. Spore formation: In this method, the parent plant produces hundreds of tiny spores. These spores are released into the air and under favorable conditions; they germinate and produce new plants. Eg: Fungus and bread molds.
