Answer :

Binary fission and Budding are the common method of Asexual reproduction.


Binary Fission: occurs when a parent cell splits into two identical daughter cells of the same size.eg. Bacteria, Amoeba.


Amoeba is a shameless tiny unicellular organism that has a porous cell membrane which encloses the cell organelle and cytoplasm, it reproduces by Binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal sized daughter cells. The genetic material is also equally partitioned, therefore the daughter cells are genetically identical to each other and the parent cell.


In this process, the nucleus of the amoeba first divides to form two daughter nuclei by the process of Karyokinesis. After the nucleus is divided into two, the process of Cytokinesis takes place in which the cytoplasm of the mother cell divides into two daughter cells.


This leads to the formation of the two daughter Amoebae cell having nucleus and its own cell organelles.



Budding: occurs when a parent cell forms a bubble-like bud. The bud stays attached to the parent cell while it grows and develops. When the bud is fully developed, it breaks away from the parent cell and forms a new organism.eg: Yeast.


Yeast is a unicellular eukaryotic micro-organism belongs to the kingdom Fungi. Yeast size vary greatly depending on the species, typically measuring 3-4μm in diameter. Most yeasts reproduces asexually by Budding.


First it produces a small protuberance on the parent cell that grows to a full size and forms bud. The nucleus of the parent cell splits into the daughter nucleus and migrates into the daughter cell. The bud detaches from the mother’s body by forming a constriction at the base. Budding will repeat forming a chain of bud cells. The daughter cll produced during the process is generally smaller than the mother cell.
