Web21. dec 2013. · The apogamous (asexual) life cycle of certain ferns means that they produce 32, larger than normal diploid spores per sporangium, instead of the normal 64 haploid spores (Moran, 2004). Other apogamous taxa with higher polyploid chromosome numbers (triploid, tetraploid, hexaploid, etc.) cannot reproduce sexually either.

WebThe life cycle of Batrachospermum consists of two gametophytic phases alternating with one sporophytic phase which is, however, confined in the zygotic stage. The early gametophytic phase—Chantransia stage, is formed by the germination of the carpospore which is the product of post-fertilization stages. WebThey usually arise in groups of three. Of the three leaves, two lateral ones float on the surface of water while the third one is submerged. There is a distinct morphological differences between the submerged and floating leaves. The submerged leaves are highly dissected, long and filiform. They very much resemble the roots.
