What is Asexual Reproduction: Budding

1 36

In asexual reproduction, one individual produces offspring that are genetically identical to Budding

it. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction. Budding is one of the types of asexual reproduction. Budding is a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. Budding is characteristic of a few unicellular organisms (e.g., certain bacteria, yeasts, and protozoans); however, a number of metazoan animals (e.g., certain cnidarians species) regularly reproduce by budding.

Process of Budding in Hydra

Asexual budding in hydra takes place during summer months, when the animal is well-fed and healthy. Near the middle or in the posterior part of repeated multiplication of the epidermal interstitial cells; this grows as a bud with its wall consisting of epidermis and gasrodermis and the interior lumen in continuation with the parent gastro vascular cavity. The bud enlarges, develops a mouth and a circle of tentacles at its free end. When full grown, the bud constricts at the base and finally separates from the parent body. It feeds and grows into an adult hydra. occasionally, several buds occur at the same time on a single parent, and these in turn may develop secondary buds, so that a group is formed which temporarily resembles a colonial hydroid. This process of budding is same in yeast and other organisms as in hydra.

Conclusion

In this type of asexual reproduction, there is no need of another partner as in sexual reproduction. Such reproduction is characterized by exponential growth phases. A disadvantage is that there is little or no genetic variation, so habitat adaptation is not as rapid as would be expected with eukaryotic sexual reproduction. There is no evolution in this type of reproduction but reproductive cycle is small in this type of asexual reproduction. Through budding organisms are reproduced in very less time.
