Log structured file system fragmentation asexual reproduction


Asexual reproduction is a mode of reproduction in which, a new offspring is produced from a single parent.

The offspring produced are identical to each other, both physically as well as genetically. They are the exact copies of their parent cell. Hence, they are called clones. Asexual reproduction is observed in both unicellular and multicellular organisms. Organisms choose to reproduce asexually by different means.

Some of the asexual methods are binary fission e. Amoeba, bacteriabudding e. Hydrafragmentation e. Planariaspore formation e. During asexual reproduction, the parent cell divides into two or more cells. Unicellular organisms show different patterns of cell division according to their cell Log structured file system fragmentation asexual reproduction i.

For example, amoeba can divide itself into two at any plane but the division in euglena is longitudinal. Fission can be of two types, namely, binary fission and multiple fission. In binary fission, parent cell divides into two equal halves called daughter cells. Daughter cells are identical to each other and to their parent cell. Organisms like amoeba, bacteriaeuglena, etc.

Fragmentation is another mode of asexual reproduction. Multicellular organisms like planaria, spirogyra, etc.

The parent body divides into two or more fragments. Later, each fragment develops into a new individual. When a lizard loses its tail, it grows a new one. This is called regeneration. In many organisms, there are specialized cells, which can differentiate and grow into a new organism.

Organisms like hydra and planaria also show regeneration. In these organisms, when the cell divides into numerous pieces, each piece proliferates and differentiates to regenerate new organisms.

Some organisms develop buds on their body. These buds develop into a new individual. This is called budding. An example is a hydra.

From the parent hydra, a bud arises which eventually matures into a new hydra. Once it is matured, it detaches from the parent body. Plants reproduce asexually through their vegetative parts such as leaves, roots, stem, and buds. This is called vegetative propagation.

Vegetative propagation is much faster than the sexual reproduction in plants. This can be done artificially as well, which is widely employed in horticulture. Spore formation is another means of asexual reproduction.
