Editing Euglenid (section)

== Reproduction ==
Although euglenids share several common characteristics with animals, which is why they were originally classified as so, no evidence has been found of euglenids ever using [[sexual reproduction]]. This is one of the reasons they could no longer be classified as animals.{{dubious|1=Animals? Really?|date=February 2024}}

For euglenids to reproduce, [[asexual reproduction]] takes place in the form of [[binary fission]], and the cells replicate and divide during [[mitosis]] and [[cytokinesis]]. This process occurs in a very distinct order. First, the [[basal bodies]] and flagella replicate, then the [[cytostome]] and microtubules (the feeding apparatus), and finally the nucleus and remaining [[cytoskeleton]]. Once this occurs, the organism begins to cleave at the basal bodies, and this cleavage line moves towards the center of the organism until two separate euglenids are evident.<ref>{{Cite web|url=http://tolweb.org/Euglenida/97461|title=Euglenida|website=tolweb.org|access-date=2017-03-30}}</ref> Because of the way that this reproduction takes place and the axis of separation, it is called longitudinal [[cell division]] or longitudinal binary fission.<ref>{{Cite web|url=http://euglenabiology.weebly.com/reproduction.html|title=Reproduction|website=Euglena|access-date=2017-03-31}}</ref>
