- No fusion of gametes is involved, a vegetative part of the parent is involved in the process
- The different methods of asexual reproduction include:

- Budding: Found in yeasts or hydra, where a part (bud) of the organism grows into a new organism
- Vegetative propagation: A vegetative part of the plant grows into the entire plant due to totipotency
- Fragmentation: A mature algae breaks into smaller but complete pieces called fragments which is capable of surviving on its own
- Spores: Asexual reproduction found in plants and algae during unfavorable conditions
