Cyanobacteria and archaebacteria are two of the most important groups of bacteria. They are the source of all terrestrial life, from mushrooms to humans, and both are important in the cycling of carbon in our planet’s oceans.

Cyanobacteria and archaebacteria differ in many ways that can help us understand how they have evolved over time. Here are the key differences:

  1. Cyanobacteria have a single membrane, while archaebacteria have multiple membranes.
  2. Cyanobacteria contain chlorophyll, while archaebacteria do not produce chlorophyll.
  3. Cyanobacteria can photosynthesize using sunlight as an energy source, while archaebacteria cannot use sunlight as an energy source because they do not contain chlorophyll-containing cells or green pigment molecules (chlorophylls).
  4. Cyanobacteria reproduce asexually through binary fission or budding; however, unlike other bacteria that reproduce sexually by fragmentation of cells (sexual reproduction), cyanobacteria form planospores that do not contain genetic material but instead contain only the nucleic acid DNA or RNA sequences necessary for the formation of new bacterial colonies (binary fission); these planospores then germinate into daughter cells.
