In what way is binary fission different from mitosis?

Binary fission is asexual reproduction where singled cell organisms copies of themselves. Mitosis is cell division that a cell and results in two newly formed cells that are identical. Binary fission is making copies of a cell, and mitosis is splitting a cell into two new indetical new ones.

Explanation:

Mitosis is a type of cell division that takes place among non-sex cells (somatic cells). This type of cell replication is designed to increase the number of cells during the blastogenesis and embryogenesis of both animals and plants. The most distinct characteristic of the mitotic process is the production of two product cells (daughters) which are similar to each other as well as to their original cell (mother) in both quantitative and qualitative aspects

Binary fission has three types: simple, transverse, and longitudinal binary fission. Simple binary fission happens in amoebas wherein the division goes by any plane. Transverse binary fission happens among paramecium and planaria wherein the cytoplasmic division plane matches the specimen’s transverse axis. Longitudinal binary fission occurs in the euglena when the plane matches the longitudinal alignment.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
