Definition

1. Noun:
   • A taxonomic division of bacteria: "division eubacteria" refers to a major group of one-celled monerans (prokaryotic organisms) characterized by simple cells with rigid walls. Some motile types within this division possess flagella for movement. It is a classification term in biological taxonomy.

Usage Examples

• Noun:
  • The domain Bacteria is primarily composed of organisms from the division Eubacteria.
  • Scientists study the genetic material of division Eubacteria to understand bacterial evolution.

Advanced Usage

• In taxonomic hierarchy: The term is used in formal biological classification to denote a specific rank below kingdom and above class.
  • In some classification systems, "division" is equivalent to "phylum" for bacteria and plants.

Variants and Related Words

• Eubacteria (n): Often used synonymously to refer to the group itself, especially in less formal taxonomic contexts.
  • Eubacteria are distinct from archaebacteria.
• True bacteria (n): A common, informal name for this group.

Synonyms

• True bacteria: A descriptive synonym emphasizing the distinction from archaea.
• Bacteria (in a broad, traditional sense): While modern taxonomy separates domains, this term is sometimes used loosely.

Notes on Meaning

• This is a specialized scientific term. In modern taxonomic systems (like the three-domain system), the term "Eubacteria" is often used at the domain level (Domain Bacteria), making "division Eubacteria" a historical or specific systematic ranking within older classifications. The core meaning refers to typical, common bacteria.

Noun

1. one-celled monerans having simple cells with rigid walls and (in motile types) flagella
