Solution

Asexual reproduction:

  1. It is a form of reproduction in which a single parent produces a new offspring.
  2. The new individuals developed are exact copies of their parents.
  3. They are clones of their parents.

Various methods of asexual reproduction:

Vegetative propagation

  1. In vegetative propagation, new plants are produced from roots, stems, leaves, and buds.
  2. It is a form of asexual reproduction.
  3. Examples- Tuber of potato, the rhizome of ginger.

Budding

  1. Bud is a small outgrowth that grows and gets detached from the parent body.
  2. The new detached bud grows, matures, and produces more buds.
  3. Examples- Hydra

Fragmentation

  1. In this mode of reproduction, the growth is done by rapidly breaking down into more fragments.
  2. When resources (water and nutrients) are available these fragments grow into new individuals.
  3. Examples- Algae

Fission

  1. Unicellular organism splits into new organisms.
  2. There are two types of fission:
  1. Binary fission (Amoeba, paramecium, etc.)
  2. Multiple fission (Plasmodium)

Spore Formation

  1. Reproduction is done by spores.
  2. Under favorable conditions germinate and develop into a new individual.
