- Multicellular organism - Wikipedia
A multicellular organism is an organism that consists of more than one cell, unlike unicellular organisms [1] All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium [2][3]
- How Did Multicellular Life Evolve? | News | Astrobiology
Scientists are discovering ways in which single cells might have evolved traits that entrenched them into group behavior, paving the way for multicellular life These discoveries could shed light on how complex extraterrestrial life might evolve on alien worlds
- Multicellular - Definition Examples of Multicellular Organisms
Organisms made up of more than one cell are categorized as multicellular organisms However, multicellular organisms haven’t always existed Following the formation of the Earth, it took one billion years for a unicellular organism to appear on the planet
- Life - Multicellularity, Evolution, Adaptation | Britannica
Life - Multicellularity, Evolution, Adaptation: Since multicellularity evolved independently in every major group of microorganisms, the blurred distinction between single-celled and many-celled organisms has become obsolete The protists are divisible into about 35 unambiguous groups called phyla
- Understanding Multicellularity: The Functional Organization of the . . .
Multicellularity is a widespread phenomenon that cuts across all the domains of life, spanning from bacterial biofilms to plants and metazoans Its most ancient eukaryotic instances date back to around 1 6 billion years ago in the case of red algae (Bengtson et al , 2017)
- What Do We Mean by Multicellularity? The Evolutionary Transitions . . .
Multicellular entities are defined as Multicellular Groups, Multicellular Individuals, or Multicellular Organisms, reflecting the stages of the evolutionary transition from single cells to multicellularity imbedded within the hierarchical structure of life
- Multicellularity: The Evolution of Differentiation - Developmental . . .
One of evolution's most important experiments was the creation of multicellular organisms There appear to be several paths by which single cells evolved multicellular arrangements; we will discuss only two of them here (see Chapter 22 for a fuller discussion)
- Volvox, Chlamydomonas, and the Evolution of Multicellularity
How does multicellularity evolve? Scientists who study a family of green algae that includes unicellular Chlamydomonas and multicellular Volvox are beginning to find answers to this question
