Asexual Reproduction

The process of formation of offspring from parent body is generally called asexual reproduction. In

 asexual reproduction process no fusion of gametes take place. The cell division is mitosis in asexual reproduction. In this process characters of offspring are exactly same as parents and no variation occurs. Depending upon organism there are following types of asexual reproductions

  1. Fission: Fission is the process of division of one species into two or more than two species. If on organism divides to two, it is called binary fission and if it divides into more than two organisms it is called multiple fission. Generally unicellular organisms like amoeba, paramecium, euglena reproduce by fission.  
  2. Budding: in some organisms buds are formed on side of main body and by detaching of bud new organism is formed, this is called budding. Hydra and yeast reproduce by budding.
  3. Fragmentation: The process of formation of new organism from detached part of parent organism is called fragmentation. Spirogyra reprocess from fragmentation.
  4. Sporulation:  Some plants produce tiny dust called spore from which new organism develops and it is called sporulation. Fern, moss, mucor, mould etc reproduce by this process.
  5. Regeneration: The process of formation of new animal from the certain part of parent animal is called regeneration. Hydra, planeria, tapeworm, star fish reproduce by regeneration process.
  6. Vegetative propagation: The process of formation of new plant from vegetative parts(stem, root, leaf, rhizome etc) of plant is called vegetative propagation………..Read More
