==Classification of spores== Spores can be classified in several ways such as by their spore producing structure, function, origin during life cycle, and mobility. Below is a table listing the mode of classification, name, identifying characteristic, examples, and images of different spore species. {| class="wikitable mw-collapsible mw-collapsed" !Mode of Classification ! colspan="2" |Name !Identifying Characteristic !Example Spore Containing Organism !Image |- | rowspan="10" |Spore Producing Structure | colspan="2" |[[Sporangium|Sporangiospore]] |Produced by [[sporangium]] |[[Zygomycota|Zygomycetes]] |[[File:Sporangium of fungi.jpg|thumb|Sporangium of Fungi]] |- | colspan="2" |[[Zygospore]]s |Produced by [[zygosporangium]] |[[Zygomycota|Zygomycetes]] |[[File:Rhizopus_zygospores.jpg|thumb|Zygospores on [[Rhizopus oryzae|Rhizopus]]]] |- | colspan="2" |[[Ascus|Ascospores]] |Produced by [[ascus]] |[[Ascomycota|Ascomycetes]] |[[File:Bitunicate_ascus_and_ascospores_of_Didymella_rabiei.png|thumb|Ascospores of ''[[Didymella rabiei|Didymella Rabiei]]'']] |- | colspan="2" |[[Basidiospore]]s |Produced by [[basidium]] |[[Basidiomycota|Basidiomycetes]] |[[File:Basidium_schematic.svg|thumb|Typical reproductive structure of a [[Echigoshirayukidake (Basidiomycetes-X)|basidiomycete]], including the [[basidiospore]] and [[basidium]]]] |- | colspan="2" |[[Aeciospore|Aecispores]] |Produced by [[aecium]] |Rusts and Smuts |[[File:Aecium sp.jpg|thumb|Aecia on foliage]] |- | colspan="2" |[[Urediniospore]]s |Produced by uredinium |Rusts and Smuts |[[File:Puccinia thaliae urediniospores.jpg|thumb|Uredinospores]] |- | colspan="2" |[[Teliospore]]s |Produced by [[Telium|teilum]] |Rusts and Smuts |[[File:Puccinia helianthi (teliospores).jpg|thumb|Microscopic image of teliospores]] |- | colspan="2" |[[Oospore]]s |Produced by [[oogonium]] |[[Oomycete]]s |[[File:10554_oospore.jpg|thumb|Oospores of ''[[Kauri dieback|Phytophthora agathidicida]]'']] |- | colspan="2" |[[Carpospore]]s |Produced by carposophorophyte |[[Red algae|Red Algae]] |[[File:Rhod1004.jpg|thumb|Light microscopy of ''[[Polysiphonia]]'' showing a carpospores and carposporophyte inside]] |- | colspan="2" |[[Tetraspore]]s |Produced by [[Tetrasporaphyte|tetrasphorophyte]] |[[Red algae|Red Algae]] |[[File:Polysiphonia_tetraspores_WM2.jpg|thumb|Tetraspores of ''[[Polysiphonia]]'']] |- | rowspan="3" |Function | colspan="2" |[[Chlamydospore|Chalmydospore]] |Thick-walled [[resting spore]]s of fungi produced to survive in unfavorable conditions |[[Ascomycota|Asomycota]] |[[File:Candida_pseudohyphae,_chlamydospores,_blastospores.png|thumb|[[Hypha|Pseudohyphae]], chlamydospores and [[blastospore]]s of [[Candida (fungus)|''Candida'' yeast]].]] |- | rowspan="2" |Parasitic Fungal Spore |Internal Spores |Germinate within a host | | rowspan="2" |[[File:Pink_fungal_parasite_on_lichen_-_geograph.org.uk_-_1040204.jpg|thumb|A parasitic pink fungi on a [[Lichen]] tree]] |- |External (Environmental) spores |Spores released by the host to infest other hosts <ref>{{Cite web |date=2008-06-26 |title=Biology of Microsporidia |url=http://www.modares.ac.ir/elearning/Dalimi/Proto/Lectures/week15/biology.htm |access-date=2024-03-24 |archive-url=https://web.archive.org/web/20080626082941/http://www.modares.ac.ir/elearning/Dalimi/Proto/Lectures/week15/biology.htm |archive-date=26 June 2008 }}</ref> | |- | rowspan="3" |Origin During Life Cycle | rowspan="2" |Meiospores |[[Microspore]]s |Produced sexually through [[meiosis]], and give rise to a male [[gametophyte]] |[[Pollen]] in seed plants |[[File:Microspore-formation.svg|thumb|In [[plant]]s, [[microspore]]s, and in some cases megaspores, are formed from all four products of meiosis.]] |- |[[Megaspore]]s (macrospores) |Produced sexually through [[meiosis]], and give rise to a female [[gametophyte]] |[[Ovule]] in seed plants |[[File:Macrospore-formation.svg|thumb|In contrast, in many [[seed plant]]s and heterosporous [[fern]]s, only a single product of meiosis will become a [[megaspore]] (macrospore), with the rest degenerating.]] |- | colspan="2" |[[Conidium|Mitospores]] |Produced asexually though [[mitosis]] |[[Ascomycota|Ascomycetes]] |[[File:Morchella conica 1 beentree.jpg|thumb|Ascomycete containing mitospores]] |- | rowspan="5" |Mobility | colspan="2" |[[Zoospore]]s |Mobile through [[Flagellum|flagella]] |Some algae and fungi |[[File:Zoospores - Reproductive Structure of the Phytophthora.png|thumb|Microscopic image of a Zoospore]] |- | colspan="2" |Aplanospores |Immobile, however still produce flagella | | |- | colspan="2" |[[Autospore]]s |Immobile spores that '''do not''' produce flagella | |[[File:Jenufa SAG 2383.jpg|thumb|Autospores of a strain of ''Jenufa aeroterrestrica'']] |- | colspan="2" |[[Ballistospore]]s |Forcibly discharged from the fungal [[Sporocarp (fungus)|fruiting body]] due to internal force (such as built up pressure) |Basidiospores and/or part of the genus ''Pilobus'' |[[File:Abb2.5 Fungi Basidiomycota basidium basidiospore ballistospore Bullers drop catapult mechanism 2021 (M.
