Fission
Fission (Medicine)
Fission (pronunciation: /ˈfɪʃən/) is a term used in the field of medicine to describe the process of cell division, where one cell divides into two or more separate cells.
Etymology
The term 'fission' originates from the Latin word 'fissio', which means 'a cleaving or splitting'. In the context of medicine, it refers to the process of cell division.
Process
Fission in medicine is a type of asexual reproduction where an organism or cell makes a copy of itself. This process is common in microorganisms, such as bacteria and protozoa. The parent organism divides into two or more organisms, each carrying a copy of the original genetic material.
Types of Fission
There are two main types of fission in medicine: binary fission and multiple fission.
- Binary Fission: This is the most common form of fission, where a single cell divides into two equal parts. Each new cell contains an exact copy of the parent cell's genetic material.
- Multiple Fission: In this type of fission, a single cell divides into many new cells. This is common in some species of protozoa.
Related Terms
- Mitosis: A type of cell division in which a cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell.
- Meiosis: A type of cell division that results in four daughter cells, each with half the number of chromosomes of the parent cell. This process is essential for sexual reproduction.
- Cytokinesis: The physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
