Which of following pairs is not correctly matched?

The correct answer is Fragmentation- Echinoderms.

Key Points

• Asexual Reproduction:
  • It is the process in which a new individual is formed by the involvement of a single parent with or without the involvement of the gamete formation.
  • The individuals produced are genetically and morphologically similar.
  • It occurs in unicellular organisms where cells divide by mitotic division and no fertilization takes place. The division occurs very rapidly.

Additional Information

• Types Of Asexual Reproduction
  • Binary Fission-
    • It is seen in amoeba and euglena.
    • The parent cell undergoes mitosis and increases in size. The nucleus also divides.
    • Two identical daughter cells are obtained, each containing a nucleus. Prokaryotes like bacteria majorly reproduce by binary fission.
  • Budding-
    • In this, the offspring grows out of the body of the parent.
    • It remains attached to the parent until it matures.
    • After maturation, it detached itself from the parent and lives as an individual organism.
    • This form of reproduction is most common in Hydras.
  • Fragmentation-
    • In some organisms like Planarians, when the body of an organism breaks into several pieces each piece grows into an individual offspring. This is known as fragmentation.
    • It can occur through accidental damage by predators or otherwise, or as a natural form of reproduction.
    • In few animals such as seastar, a broken arm grows into a complete organism.
  • Regeneration-
    • It is a modified form of fragmentation and occurs mostly in Echinoderms.
    • When a part of an organism, like an arm, detaches from the parent body, it grows into a completely new individual. 
  • Parthenogenesis-
    • This is a form of asexual reproduction where the egg develops without fertilization.
    • This process occurs in bees, wasps, ants, aphids, rotifers, etc. Ants, wasps, and bees produce haploid males. Parthenogenesis has been observed in a few vertebrates such as hammerhead sharks, Komodo dragons, blacktop sharks when the females were isolated from the males.
