Their development is accompanied by cellular specialization and division of labor: cells become efficient in one process and are dependent upon other cells for the necessities of life.
- Multicellular organism - WikipediaA multicellular organism is an organism that consists of more than one cell, in contrast to unicellular organism. 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.
- How Did Multicellular Life Evolve? | News | AstrobiologyScientists 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. Researchers detailed these findings in the October 24, 2016 issue of the journal ...
- Life - Multicellularity, Evolution, Adaptation | BritannicaLife - 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.
- Multicellularity: From brief encounters to lifelong unions | eLifeWhen multicellular organisms developed from unicellular ancestors, it was a major evolutionary transition (Maynard Smith and Szathmary, 1995). Multicellular life is thought to have evolved by two mechanisms—clonal development or aggregative development ( Grosberg and Strathmann, 2007 ; Figure 1 )—but we are just beginning to understand its ...
