Zorluk: OrtaKingdom Monera: Bacteria and Cyanobacteria

A culture of bacteria in a nutrient-rich broth undergoes rapid population expansion under optimal environmental conditions. Which mechanism is primarily responsible for the asexual reproduction and multiplication of these prokaryotic organisms?

  1. Binary fission, resulting in two genetically identical daughter cellsCevap
  2. B
    Mitotic division involving spindle apparatus assembly and nuclear membrane breakdown
  3. C
    Germination of reproductive spores formed by cellulose cell wall cleavage
  4. D
    Replication by assembling protein capsids inside host cytoplasm

Cevap

Binary fission, resulting in two genetically identical daughter cells
In Kingdom Monera, bacteria reproduce asexually under favorable conditions through binary fission. The single circular chromosome replicates, attaches to the plasma membrane, and the cell elongates before invaginating to yield two genetically identical cells.

Adım Adım Çözüm

1
Identify the biological group and kingdom of bacteria
Bacteria belong to Kingdom Monera and are prokaryotic organisms.
Prokaryotic cells lack membrane-bound organelles, a true nucleus, and mitotic structures.
2
Determine the standard mode of cellular reproduction in prokaryotes under favorable conditions
Prokaryotes replicate their single circular chromosome and divide by binary fission.
Binary fission allows rapid exponential growth by splitting one parent cell into two identical daughter cells without mitosis.
