Types of Asexual reproduction:
- Binary fission: A unicellular organism divides into two daughter cells. Parent generation does not exist post binary fission. Ex - Amoeba
- Multiple fission: Nucleus of mother cell divides into daughter nuclei. A cyst develops around the mother cell, which ensures safety during unfavourable conditions. When favourable condition resumes, the cyst disintegrates, and daughter nuclei develop into new individuals. Ex – Plasmodium, Entamoeba
- Budding: Nucleus produces a daughter nucleus. This nucleus moves to a bud formed at one end of the cell. The bud then detaches from the mother cell to develop into a new individual. Ex – Yeast.
