Fission

Definition

Fission is a form of asexual reproduction where an organism divides into two or more separate entities. It allows for rapid population increase without the need for a mate.

5 Must Know Facts For Your Next Test

1. Fission is common in single-celled organisms such as bacteria and protozoa.
2. The process results in offspring that are genetically identical to the parent organism.
3. Binary fission involves the division of one cell into two, while multiple fission involves the division into more than two cells.
4. Fission can be influenced by environmental factors like temperature and nutrient availability.
5. Some multicellular organisms, like certain types of worms, also reproduce through fission.
