Developmental Biology of Fern Gametophytes
Although evolutionary considerations are not emphasized in this book, we shall
nonetheless begin this part with an account of the two major spore types found in
ferns. Homospory and heterospory One of the most important concepts ...

which the spines of the echinate sculpture are over 3 m long. Cf. low-spine. hilate

Homospory, Anisospory, Incipient Heterospory and Heterospory Before
discussing the origin of ovule and integument, it will be worthwhile to relate the
steps through which plant groups ultimately attained heterospory from
homospory.
S. P. Bhatnagar, Alok Moitra, 1996

International Review of Cell and Molecular Biology
However, although most of the species in bryophyte are homospory, many are
dioecious species. In the latter situation, the differentiation leading to
heterogametogenesis should be traced back to early development after spore
germination ...

Cf: heteroscedasticity. homospore (ho'-mo-spore) One of the spores of an
embryophytic plant that reproduced by homospory; a plant spore functioning as
either male or female in reproduction. Its range is Silurian to Holocene. Syn:
isospore.
Julia A. Jackson, James P. Mehl, Klaus K. E. Neuendorf, 2005
Homospory, the production ofone kind ofspore, is characteristic ofbryophytes,
most club mosses, and most ferns, including whisk ferns and horsetails. In
homospory spores give rise to gametophyte plants that produce both egg cells
and sperm ...

Plants: Diversity and Evolution
Homospory = spores of the same size. Anisospory = spores of different sizes in
the same sporangium. Heterospory = spores of different sizes, and normally
different sexes, produced in different sporangia. Heterothally = gametophytes of ...
