unicellular

[ˌjuːnɪˈsɛlʊlə ]

Definition

Context #1 | Adjective

biological description

Unicellular refers to organisms that consist of a single cell. These organisms carry out all the necessary functions of life within that one cell. They can be found in a variety of environments, including freshwater, saltwater, and even in the human body. Examples of unicellular organisms include bacteria, archaea, and many protists. Despite their simplicity, unicellular organisms play crucial roles in ecosystems and are important for processes such as decomposition and nitrogen fixation.

Synonyms

monadic, single-celled.

Examples of usage

Origin of 'unicellular'

Main points about word origin

  • The term comes from the Latin words 'uni' meaning 'one' and 'cellula' meaning 'small room'.
  • First used in the scientific context in the 19th century to describe simple organisms.
  • It's the opposite of 'multicellular,' indicating life forms made of many cells.

The term 'unicellular' is derived from the Latin prefix 'uni-', meaning 'one' or 'single,' combined with the word 'cellular,' which relates to the cell, the basic structural and functional unit of living organisms. The concept of unicellular organisms dates back to the discovery of single-celled entities such as bacteria in the 17th century. Microbiologists and naturalists began exploring these simple forms of life through the advent of the microscope. The classification of life into unicellular and multicellular organisms further developed during the 19th century as scientists began to understand the complexity and diversity of living organisms. Advances in cell biology in the 20th century have illuminated the intricate processes occurring within unicellular organisms, revealing their significance in ecology, evolution, and biotechnology.
