The 13 pages that link to Heterospory, each with the reason it gives.

• SporophyteRelated: Some sporophytes produce distinct microspores and megaspores, precursors to separate sexes.

• GametophyteRelated: It separates gametophyte sexes by the kinds of spores from which they develop.

• LycophyteRelated: Some lycophytes separate male and female gametophyte development through different spores.

• StrobilusRelated: Some strobili bear distinct sporangia producing microspores and megaspores.

• Pollen coneNarrower topic: Pollen cones produce microspores, one of the two spore types.

• ArchegoniumRelated: In some seed plants, reduced female gametophytes and archegonia develop from megaspores.

• IsoetesRelated: Isoetes produces both spore sizes, in separate sporangia at leaf bases.

• SelaginellaRelated: Most Selaginella species produce separate microspores and megaspores.

• ArchaeopterisRelated: Some Archaeopteris reproductive structures show differentiation relevant to the evolution of seed-like reproduction.

• LycopodiopsidaRelated: Quillworts and Selaginella produce separate microspores and megaspores.

• SalvinialesRelated: Living water ferns produce separate male and female spores, unlike most ferns.

• LycopodiaceaeCompared with: This contrasts with the single spore type typical of Lycopodiaceae.

• ProgymnospermRelated: Some progymnosperms produced distinct spore types, a reproductive pattern relevant to seed evolution.
