Is s phase diploid or haploid
WitrynaTHE HAPLOID LIFE CYCLE. Haploid life cycle is the most common in algae (without dikaryotic phase) and most fungi (with dikaryotic phase). Colonial alga such as red alga, brown alga, and green alga and filamentous alga such as red, green, and brown alga all exhibit haploid life cycle. A general life history includes both a 1n stage and a 2n ... Witrynato the haploid phase (Figure 1A), to diplontic, where mitoses are restricted to the diploid phase, as in humans (Figure 1B). Many organisms fall in between these extremes, however, with biphasic (or haploid–diploid) life cycles, where cell divisions and vegetative growth occur in both haploid and diploid phases (Figure 1C).

WitrynaThe whole process of female gametophyte development occurs in two different phases. The first phase involves the megasporogenesis, where a single diploid mother cell undergoes meiosis to form haploid megaspore tetrad out of which only one will survive and other three disintegrate. The functional megaspore grows into an embryo sac. WitrynaIn the filamentous green alga (Spirogyra) and black bread mold (Rhizopus), the only part of the life cycle that is diploid is the zygote or dormant zygote (zygospore), while the entire algal or fungal body (thallus) is haploid. In the moss, the diploid phase consists of a sporangium and stalk that grows out of the haploid female gametophyte.
