What is Cisterna?
{{Other uses}} A '''cisterna''' (plural: '''cisternae''') is any membrane-bound sac.<ref>{{Cite book|url=https://www.worldcat.org/oclc/1100041140|title=A dictionary of biology.|date=2019|isbn=978-0-19-186081-2|edition=8th|location=Oxford|oclc=1100041140|last1=Hine |first1=Robert }}</ref> They can be found in the [[Golgi apparatus]] and in the [[endoplasmic reticulum]]. It is the flattened sac on the branch of the endoplasmic reticulum and the curved sac on the branch of the Golgi apparatus. == Position in cells == [[File:Golgi apparatus (editors version).svg|thumb|This illustration shows where the cisternae can be found on the Golgi apparatus.]] [[File:Nucleus ER golgi.svg|thumb|200px|'''1'''&nbsp;[[Cell nucleus|Nucleus]]{{nbsp|2}} '''2'''&nbsp;[[Nuclear pore]]{{nbsp|2}} '''3'''&nbsp;Rough endoplasmic reticulum (RER){{nbsp|2}} '''4'''&nbsp;Smooth endoplasmic reticulum (SER){{nbsp|2}} '''5'''&nbsp;[[Ribosome]] on the rough ER{{nbsp|2}} '''6'''&nbsp;[[Protein]]s that are transported{{nbsp|2}} '''7'''&nbsp;Transport [[Vesicle (biology)|vesicle]]{{nbsp|2}} '''8'''&nbsp;[[Golgi apparatus]]{{nbsp|2}} '''9'''&nbsp;Cis face of the Golgi apparatus{{nbsp|2}} '''10'''&nbsp;Trans face of the Golgi apparatus{{nbsp|2}} '''11'''&nbsp;'''''Cisternae of the Golgi apparatus''''']] Cisternae are on the trans face of the Golgi apparatus. They are in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus. ==Roles== The cisternae play an important role in the packaging, modification, and transport in the [[cell]]. They help the transport of proteins and other enzymes from the Golgi. Cisternae transport proteins in the endoplasmic reticulum to the vesicles of the Golgi apparatus. ==References== {{reflist}} [[Category:Cell biology]] {{-}} {{biology-stub}}
