Haploid or Haplobiontic A* life cycle. The term haplobiontic means single
generation. In this life cycle type (Figs. 44.B; 45 A) the nuclei follow the sequence,
nuclear fusion -* meiosis -» mitosis. Thus nuclear fusion is immediately followed

5.19B); it is called the haplobiontic-diploid life cycle. A multicellular diploid
individual produces gametes by meiotic cell division. The zygote resulting from
fertilization undergoes repeated mitotic cell division to produce the multicellular ...

Three kinds of sexual cycles are distinguished in fungi: Haplobiontic-haploid life
cycle The term haplobiontic means single generation. If there is only one free-

haploid ...

BIOLOGIA PARA O ENSINO MEDIO
Sexual reproduction may take place through three different types of life cycles:
the haplontic (the being is haploid) haplobiontic (a single type of being) cycle; the
diplontic (the being is haploid) haplobiontic (a single type of being) cycle; and the
...

... be haploid, but if meiosis occurs during gametogenesis, as in Codium, the
plants will be diploid.) In fresh waters, vegetative plants are often haploid, with
only the zygote being diploid; haploid, haplobiontic seaweeds appear to be quite
rare.

Plants: Diversity and Evolution
Life cycles Three major kinds of life cycles can be distinguished; haplobiontic,
diplobiontic and haplodiplobiontic (Figure 1.23). Haplobiontic organisms do not
produce a diploid multicellular individual and produce spores more or less
directly ...

Haplobiontic. Type. This type of life cycle occurs in Nemalionales (
Batrachospermum). During sexual reproduction the male nucleus of the
spermatium unites with that of the egg. The zygote nucleus immediately divides
by meiosis so that the ...

The probable course of evolution might be: (i) haplobiontic types with reduction
immediately after fertilisation and no morphological alternation; (2) haplobiontic
types with reduction in the carpospores; (3) diplobiontic types with morphological

(a) Charophytes, the closest living relative of land plants, have a life cycle

involving two ...
