haploid phase

The haploid phase begins when the mature organism releases many spores, which then germinate to become male or female gametophytes.

The life cycle of coccolithophores is characterized by an alternation of diploid and haploid phases.

In the Fucales there is no haploid phase in the reproductive cycle and therefore no alternation of generations.

In the whole cycle, zygotes are the only diploid cell; mitosis occurs only in the haploid phase.

Heterococcoliths are produced in the diploid life-cycle phase and holococcoliths in the haploid phase.

The existence of a multicellular, haploid phase in the life cycle between meiosis and gametogenesis is also referred to as alternation of generations.

Holococcoliths are produced only in the haploid phase, lack radial symmetry, and are composed of anywhere from hundreds to thousands of calcite crystals.

A protonema (plural: protonemata) is a thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life cycle.

In sexual reproduction, organisms have a haploid phase, with one set of chromosomes, alternating with a diploid phase with two sets of chromosomes.

Haploid cells may divide again (by mitosis) to form more haploid cells, as in many yeasts, but the haploid phase is not the predominant life cycle phase.

"The sandtrout . . ." He fell silent and she wondered why he kept referring to the haploid phase of the planet's giant sandworm, but she dared not prod him.

Many of the bacteria that possess NHEJ proteins spend a significant portion of their life cycle in a stationary haploid phase, in which a template for recombination is not available.

Although motility and colony formation vary according to the life cycle of different coccolithophore species, there is a general alternation between a motile, haploid phase, and a non-motile, colony-forming diploid phase.

The species of Ulva are reproductively isomorphic, the diploid vegetative phase is the site of meiosis and releases haploid zoospores, which germinate and grow producing a haploid phase alternating with the vegetative phase.
