Answer

Reproduction in Unicellular Organisms

Unicellular organisms, such as bacteria and protists, reproduce through various methods. One of the primary methods they use is fission.

Fission
- Fission is a form of asexual reproduction where a unicellular organism divides into two or more daughter cells.
- This process involves the duplication of genetic material followed by the division of the cell into two identical daughter cells.
- Each daughter cell then grows and matures into an independent organism.

Fragmentation
- Fragmentation is another method of asexual reproduction where the parent organism breaks into several fragments, each of which can grow into a new individual.
- This process is commonly seen in some algae and fungi.

Vegetative Propagation
- Vegetative propagation is a form of asexual reproduction seen in multicellular organisms where new individuals are produced from vegetative parts such as roots, stems, or leaves.
- Unicellular organisms do not reproduce through vegetative propagation as they do not possess specialized vegetative structures.

Conclusion
- Therefore, the correct answer to the question is option 'A', as unicellular organisms primarily reproduce through fission by dividing into daughter cells.

Answer

Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original.For unicellular organisms, cell division is the only method used to produce new individuals. In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells that are genetically identical to the parent cell. In unicellular organisms, daughter cells are individuals.
