Prokaryotic Cell Division

Prokaryotes, including bacteria and archaea, are single-celled organisms found everywhere. They multiply rapidly through binary fission, a simple form of asexual reproduction. Their small size, quick DNA replication, and simple cell structure enable fast growth, with some bacteria dividing every 20 minutes. This rapid multiplication can lead to exponential population growth. Understanding prokaryotic cell division aids in disease prevention and environmental applications, such as using antibiotics to control harmful bacteria and employing beneficial prokaryotes in digestion and bioremediation. Prokaryotes are vital to life on Earth.

What characteristic of prokaryotes contributes to their widespread presence?

• Their complex cellular structure

• Their ability to photosynthesize

• Their rapid multiplication

• Their large size

What is the process called by which prokaryotic cells divide?

• Conjugation

• Binary fission

• Mitosis

• Meiosis

During binary fission, what happens after the DNA replicates?

• The cell undergoes meiosis

• The DNA attaches to the cell membrane

• The cell stops growing

• The cell forms a nucleus

Why can prokaryotes multiply so quickly?

• They have a high surface area to volume ratio

• They have multiple nuclei

• They require no nutrients

• They are resistant to antibiotics

How do scientists use knowledge of prokaryotic cell division?

• To create new forms of energy

• To develop new plant species

• To prevent and treat diseases

• To enhance animal growth
