Editing Frond (section)

==Related concepts==
Fronds may describe several "[[frondose]]" structures in non-plant organisms -- such as the entire bodies of [[Thallus|thalloid]] organisms, or the superficially leaf-like structures developed by some animals and fungi. Examples include frondose colonial [[Bryozoa|bryozoans]],<ref>{{Cite web|url=http://strata.uga.edu/cincy/fauna/bryozoanStudy/growthForms.html|title=Cincinnatian Fossils and Stratigraphy|website=strata.uga.edu|access-date=2019-12-05}}</ref> extinct Ediacaran biota such as [[Rangeomorph|rangeomorphs]],<ref>{{Cite journal|last1=Burzynski|first1=Greg|last2=Narbonne|first2=Guy M.|date=2015-09-15|title=The discs of Avalon: Relating discoid fossils to frondose organisms in the Ediacaran of Newfoundland, Canada|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|series=Ediacaran Environments and Ecosystems|volume=434|pages=34–45|doi=10.1016/j.palaeo.2015.01.014|issn=0031-0182|bibcode=2015PPP...434...34B}}</ref> and some macroalgae and lichens. 

In paleontology of Ediacaran marine organisms, a frond may be defined as "a rangeomorph unit with a growth tip that can generate primary branches". A frond may also refer to the entire frondose organism, including any stem or basal disc. To classify rangeomorph taxa, the frond is generally subdivided into segments as are those of a fern, and categorized by six factors: polarity, rows of branches, inflation, display/furling, alignment of branches, and presence of a basal disc.<ref>{{Cite journal|last1=Brasier|first1=Martin D.|last2=Antcliffe|first2=Jonathan B.|last3=Liu|first3=Alexander G.|date=2012|title=The architecture of Ediacaran Fronds|journal=Palaeontology|language=en|volume=55|issue=5|pages=1105–1124|doi=10.1111/j.1475-4983.2012.01164.x|s2cid=86538017 |issn=1475-4983|doi-access=free}}</ref>

Frondescence is the production of leaves; it can also refer to the abnormal development of floral parts into leafy structures, though this is usually called [[phyllody]].<ref>{{Cite book|title=Morphology of flowers and inflorescences|last=Weberling|first=Focko|date=1992|publisher=Cambridge University Press|isbn=0-521-43832-2|edition=1st pbk.|location=Cambridge [England]|pages=141|oclc=29403252}}</ref>
