Answer:
Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts to separate entities resembling the original. The object experiencing fission is usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts

HI MATE !
QUESTION :- ⬇️
Define binary ffussion.
ANSWER :- ⬇️
- Binary fission is a type of asexual reproduction typically observed in prokaryotes and few single-celled eukaryotes. In this method of asexual reproduction, there is a separation of the parent cell into two new daughter cells. This process happens with the division and duplication of the parent’s genetic matter into two parts, here, each daughter cell receives one copy of its parent DNA.
- It is a primary method of reproduction in prokaryotic organisms. Binary Fission occurs without any spindle apparatus formation in the cell. In this process, the single DNA molecule begins replication and then attaches each copy to various parts of the cell membrane. When the cell starts to get drawn apart, the original (actual) and replicated chromosomes get apart.
- However, asexual mode of reproduction has a significant drawback. All resultant cells are genetically identical, mirror copies of each other and the parent cell. Most antibiotics work on this principle. If a parent cell is vulnerable to an antibiotic, then all resultant daughter cells are vulnerable too. If a mutation occurs in their genes, then it can render a particular strain resistant to antibiotics.
- Prokaryotes such as E. coli, Archaea as well as eukaryotes such as euglena reproduce through binary fission.
