Mitosis and Cytokinesis

284.2K
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome duplication, chromosome distribution to daughter cells, and finally, cell division. The cell cycle is tightly regulated by its regulatory systems as well as extracellular signals that affect cell proliferation.
The processes of the cell cycle occur over approximately 24 hours (in typical human cells) and in two major distinguishable stages. The...

Binary Fission

66.6K
Fission is the division of a single entity into two or more parts, which regenerate into separate entities that resemble the original. Organisms in the Archaea and Bacteria domains reproduce using binary fission, in which a parent cell splits into two parts that can each grow to the size of the original parent cell. This asexual method of reproduction produces cells that are all genetically identical.

Binary Fission

5.1K
Binary fission is the primary mode of asexual reproduction in prokaryotes, such as bacteria. It results in the production of two genetically identical daughter cells. This highly efficient process ensures the rapid propagation of bacterial populations under favorable conditions and involves coordinated cellular and molecular events.DNA Replication and SeparationThe process begins with the replication of the bacterial chromosome. The circular DNA molecule unwinds at a specific origin of...

Area of Science:

  • Plant cell biology
  • Algology
  • Evolutionary biology

Background:

  • Cytokinesis is crucial for cell division in eukaryotes.
  • The phragmoplast, involved in cell plate formation, varies across plant lineages.

Purpose of the Study:

  • To investigate the cellular mechanisms of cytokinesis in Spirogyra.
  • To compare the Spirogyra phragmoplast with those in higher plants.

Main Methods:

  • Light microscopy
  • Electron microscopy

Main Results:

  • Observed early cross wall formation via septum ingrowth.
  • Described the phragmoplast composition: Golgi vesicles, microtubules, and electron-dense material.

Conclusions:

  • Spirogyra exhibits a unique cytokinesis process.
  • Spirogyra's phragmoplast may represent an evolutionary intermediate towards higher plant structures.
