b) What are its subtype
of which organism show these

Answer 1

Answer:

Organisms in the domains of Archaea and Bacteria reproduce with binary fission. This form of asexual reproduction and cell division is also used by some organelles within eukaryotic organisms (e.g., mitochondria). Binary fission results in the reproduction of a living prokaryotic cell (or organelle) by dividing the cell into two parts, each with the potential to grow to the size of the original.

Fission of prokaryotes Edit

The single DNA molecule first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicated and original chromosomes are separated. The consequence of this asexual method of reproduction is that all the cells are genetically identical, meaning that they have the same genetic material (barring random mutations). Unlike the processes of mitosis and meiosis used by eukaryotic cells, binary fission takes place without the formation of a spindle apparatus on the cell. Like in mitosis (and unlike in meiosis), the parental identity is preserved.

Answer 2

Answer:

(a) Binary fission is the process in which a unicellular organism splits (or divides) to form only two new organisms.

(b) There are four types of binary fission

1. Irregular Binary Fission

2. Longitudinal Binary Fission

3. Transverse Binary Fission

4. Oblique Binary Fission

(c) Organisms like Amoeba , Lieshmanai , Paramecium and some bacteria shows binary fission.
