Fission

Definition

Fission is a form of asexual reproduction where an organism splits into two or more separate entities. This process results in genetically identical offspring from the parent organism.

5 Must Know Facts For Your Next Test

1. Fission primarily occurs in single-celled organisms like bacteria and protozoa.
2. In animal reproduction, fission is less common but can be seen in some simple animals like flatworms.
3. The resulting organisms from fission are clones of the original parent organism, sharing identical genetic material.
4. Fission can be binary (splitting into two parts) or multiple (splitting into more than two parts).
5. Environmental conditions such as nutrient availability and temperature can influence the rate and occurrence of fission.
