Editing Euglena (section)

==Reproduction==
''Euglena'' reproduce asexually through [[Fission (biology)|binary fission]], a form of [[cell division]].  Reproduction begins with the [[mitosis]] of the [[cell nucleus]], followed by the division of the cell itself.  ''Euglena'' divide longitudinally,  beginning at the front end of the cell, with the duplication of flagellar processes, gullet and stigma.  Presently, a cleavage forms in the [[Anatomical terms of location|anterior]], and a V-shaped bifurcation gradually moves toward the [[Anatomical terms of location|posterior]], until the two halves are entirely separated.<ref>{{cite journal |first=Mary |last=Gojdics |title=The Cell Morphology and Division of Euglena deses Ehrbg |journal=Transactions of the American Microscopical Society |volume=53 |issue=4 |year=1934 |pages=299–310 |jstor=3222381 |doi=10.2307/3222381}}</ref>

Reports of [[isogamy|sexual conjugation]] are rare, and have not been substantiated.<ref>{{cite book | last1 = Lee | first1 = John J. | title = An Illustrated Guide to the Protozoa: organisms traditionally referred to as protozoa, or newly discovered groups | volume = 2 | edition = 2nd | publisher = Society of Protozoologists | year = 2000 | location = Lawrence, Kansas | page = 1137  }}</ref>
