Outline of life forms

From Wikipedia, the free encyclopedia

Life form (also spelled life-form or lifeform) is an entity that is living,[1][2] such as plants (flora) and animals (fauna). It is estimated that more than 99% of all species that ever existed on Earth, amounting to over five billion species,[3] are extinct.[4][5]

Archaea[]

  • Archaea – a domain of single-celled microorganisms, morphologically similar to bacteria, but they possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably the enzymes involved in transcription and translation. Many archaea are extremophiles, which means living in harsh environments, such as hot springs and salt lakes, but they have since been found in a broad range of habitats.

Bacteria[]

Eukaryote[]
