Question

In a prokaryotic cell, cell division takes place by...... type of reproduction.

Answer 1

Hint: Prokaryotic cells such as bacterial cells, have an undefined nuclear region called a nucleoid. The nuclear region is not bounded by a nuclear membrane. Thus, the true nucleus is absent in prokaryotes. Most of the membrane-bound cell organelles are also absent in a prokaryotic cell.

Complete answer:
As prokaryotes do not have a true nucleus, they are unable to reproduce in the same way as eukaryotic cells do. A prokaryotic cell reproduces only by an asexual mode due to the absence of sex organs. It is a simple method of reproduction. Prokaryotic organisms reproduce asexually by binary fission. It is a process by which unicellular organisms divide to produce two genetically and morphologically identical daughter cells.
Binary fission in prokaryotes is a stepwise continuous process.
> DNA replication: single circular DNA is copied which results in two identical chromosomes instead of just one.
> Chromosome segregation: Copied chromosomes separate or segregate by moving to opposite ends of the cell.
> Formation of two daughter cells: A new cell membrane begins to form in the centre of the cell and the cytoplasm divided into two. This results in forming two daughter cells. The new cell wall also forms around the two cells.

Thus, the correct answer is binary fission.

Note:
In prokaryotic cell division, the single chromosome is copied, the cell grows larger. Ultimately the two chromosomes separate and move to opposite ends of the cell. The newly formed cell membrane then grows into the centre of the cell, separating the two chromosomes, and forming two genetically identical daughter cells.
