A gametophyte (/ɡəˈmiːtəfaɪt/) is one of the two alternating multicellular phases in the life cycles of plants and algae. It is a haploid multicellular...

plants both phases are multicellular: the haploid sexual phase – the gametophyte – alternates with a diploid asexual phase – the sporophyte. A mature...

sporophytes are free-living and only briefly dependent on the maternal gametophyte. The green, photosynthetic part of the plant is technically a megaphyll...

part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the...

generations. Gametes are produced by the gametophyte, which is the haploid generation. The female gametophyte produces structures called archegonia, and...

of bryophytes are: Their life cycles are dominated by a multicellular gametophyte stage Their sporophytes are unbranched They do not have a true vascular...

produces asexual spores. This stage alternates with a multicellular haploid gametophyte phase. The sporophyte develops from the zygote produced when a haploid...

plants, the female gametophyte is produced inside the ovule within the ovary of the flower. When mature, the haploid gametophyte produces female gametes...

germinate and divide by mitosis to form a haploid multicellular phase, the gametophyte, which produces gametes directly by mitosis. This type of life cycle...

One generation, the sporophyte, gives rise to the next generation, the gametophyte asexually via spores. Spores may be identical isospores or come in different...
