Mode of cell division in prokaryotes is

Short Answer

Expert verified

Answer: The mode of cell division in prokaryotes is called binary fission, a relatively simple and quick process resulting in the formation of two identical daughter cells, each containing a single circular DNA molecule. In contrast, eukaryotic cell division involves mitosis (for somatic cells) and meiosis (for reproductive cells), which are more complex processes that involve the replication and segregation of multiple linear chromosomes and division of various organelles.

Step by step solution

Understand the concept of prokaryotes

Prokaryotes are a group of organisms that include bacteria and archaea. These organisms have a simple cell structure, lacking a nucleus and membrane-bound organelles. Their genetic material is contained within a single, circular DNA molecule.

Define binary fission as the mode of cell division in prokaryotes

Binary fission is the process by which prokaryotic cells divide. It is a relatively simple and quick process compared to mitosis and meiosis in eukaryotic cells. Binary fission results in the formation of two identical daughter cells, each containing a single, circular DNA molecule.

Describe the steps of binary fission

Binary fission can be broken down into several steps: 1. DNA replication: The circular DNA molecule replicates, producing two identical copies. 2. Partitioning of DNA: The DNA molecules move to opposite ends of the cell. 3. Cytokinesis: The cell membrane starts to pinch inward at the center of the cell, forming a constriction. 4. Separation: The constriction continues to grow until the cell is divided into two separate daughter cells, each containing one copy of the DNA molecule.

Explain the importance of binary fission in prokaryotes

Binary fission is the primary mode of reproduction for prokaryotes, allowing them to reproduce rapidly under favorable conditions. This rapid reproduction enables them to adapt quickly to changing environments, colonize new habitats, and compete with other organisms for resources.

Contrast binary fission with eukaryotic cell division

While prokaryotes undergo binary fission, eukaryotes (organisms with a nucleus and membrane-bound organelles) divide using mitosis (for somatic cells) and meiosis (for reproductive cells). Mitosis and meiosis are more complex processes that involve the replication and segregation of multiple linear chromosomes and division of various organelles. In contrast, binary fission is a faster and simpler process that results in the formation of two identical daughter cells.
