'''noun'''
  
[[Membrane]]-bound structures that occur as functional independent units of life (such as in [[unicellular]] [[organisms]], e.g. [[bacteria]], [[protozoa]], ''etc''.), or as structural or fundamental units in a biological [[tissue]] specialized to perform a particular function in [[multicellular]] [[organisms]] (e.g. [[plants]] and [[animals]]).

There are two distinct types of [[cell]]s: [[prokaryotic]] cells (e.g. [[bacterial]] cells) and [[eukaryotic]] cells (e.g. [[plant]] or [[animal]] cell). The main difference between the two is a well-defined [[nucleus]] surrounded by a membranous [[nuclear envelope]] present only in [[eukaryotic]] cells. Despite this difference they share a number of common features: the genetic information is stored in [[gene]]s, [[protein]]s serve as their main structural material, [[ribosome]]s are used to synthesize [[protein]]s, adenosine triphosphate is the main source of [[metabolic]] [[energy]] to sustain various cellular processes, and a [[cell membrane]] that controls the flow of substances into and out of the cell.
