  • Asexual reproduction is the type of reproduction in which only one individual is involved.
  • Here, no gametes are involved,but some part of the organism or the entire organism may give rise to the new individual.
  • The types are as follows :
  1. Fission
  2. Budding
  3. Regeneration
  4. Fragmentation
  5. Spore Formation
  6. Vegetative Reproduction

FISSION :

  • In pigeon, the organism divides or splits into two or more parts.
  • There are two types of fission namely binary fission and multiple fission.
  • The binary fission is shown in amoeba and leishmania.
  • These organism divide into two new organisms during division.
  • The multiple fission is shown in plasmodium.
  • During division, the plasmodium divides into many daughter cells simultaneously.
  • The yeaat on the other hand, put out small buds with separate and grow further.

FRAGMENTATION :

  • This is shown in Spirogyra.
  • After maturation, it simply breaks up in two different small pieces.
  • The new fragments further grow into new individuals.

REGENERATION :

  • Many organisms have the ability to give rise to new individual organisms from their body parts.
  • The examples include hydra and planaria.
  • Planaria can be cut into any number of pieces and each piece will grow into a new complete organism.
  • It can only be carried out by specialised cells.

BUDDING :

  • Organisms like hydra, develops a bud as an outgrowth due to repeated cell division.
  • These buds, father detached from the parent body after getting fully matured and become new independent individual.

VEGETATIVE PROPAGATION :

  • There a lot number of plants which grows with the help of different parts of a plant in some appropriate conditions.
  • This property of vegetative propagation is used in the methods of layering and grafting to grow many plants for agricultural purposes.
  • These methods make possible the propagation of plants such as fruit plants that have lost the capacity to produce seeds.
  • Theother advantage of it is that all the plants produced are genetically similar enough to the parent plant to have its characteristics.
  • This also includes the bryophyllum leaf.
  • In a bryophyllum leaf, small buds are produced in the notice along the leaf margin.
  • These buds, fall on the soil and develop a new plant.
