Definition of gametophyte in English:

gametophyte

noun ɡəˈmiːtə(ʊ)fʌɪtɡəˈmidəˌfaɪt

Botany

(in the life cycle of plants with alternating generations) the gamete-producing and usually haploid phase, producing the zygote from which the sporophyte arises. It is the dominant form in bryophytes.
Example sentencesExamples
- Many algae are characterized by an alternation of haploid gametophyte and diploid sporophyte generations.
- Bryophytes are characterized by their dominant gametophytic plant body and their sporophytes epiphytic to gametophytes.
- The alternation between haploid gametophyte and diploid sporophyte phases, known as alternation of generations, occurs in all multi-cellular plants.
- Unlike vascular plants, the haploid gametophyte generation is dominant in mosses.
- The plant life cycle alternates between a diploid sporophyte and a haploid gametophyte generation.

Derivatives

gametophytic

adjectiveɡəmiːtə(ʊ)ˈfɪtɪk

Botany

The pollen grain is the male gametophytic phase of flowering plants.
Example sentencesExamples
- Seed development requires co-ordinated expression of embryo and endosperm and is controlled by sporophytic, male gametophytic, and female gametophytic genes.
- In both species there are several layers of cells with labyrinthine walls (transfer cells) on both the sporophytic and gametophytic side of the placenta.
- Individual specimens were identified to the generic level from the morphology of the young sporophytes and the presence or absence of gametophytic trichomes.
- In barley, a combination of starvation and osmotic stress is able to induce efficiently a microspore developmental switch from the gametophytic to the sporophytic pathway, a process called androgenesis.
