represented by single cells, the zygotes (Fig. 1.3). In haplontic organisms,
asexual reproduction may occur by means of single vegetative cells, the conidia,

The haplontic life history is one in which the dominant plant is haploid (1N) with
the zygote being the only diploid (2N) stage [i.e., zygotic meiosis;
Chlaymdomonas, Fig. 6-4(A)]. Haplontic life histories are unknown in green
seaweeds, although ...
Haplontic Sexual Cycles The earliest sexual cycles to evolve were likely
haplontic, in which only haploid cells go though mitotic cell cycles (Figure 22.1).

The Evolution of Sex Determination
Among Chlorophyta, the basal Prasinophyceae are haplontic, while the more
evolved Ulvophyceae comprise haplontic (Ulotrichales), haplo-diplontic (Ulvales,
Bryopsidales, and Cladophorales), and diplontic cycles (e.g. Codium). Similarly ...

Some algal taxon that evolved cutinised spores in terrestrially produced
sporangia (replacing other forms of diaspore-releasing organs) had an
evolutionary advantage, but could not prosper as a terrestrial taxon if it produced
both haplontic ...
