गेमटोफाइट इसके अंग्रेजी अर्थ का उदाहरण

Tagbanwa Microsporangia are sporangia that produce microspores that give rise to male gametophytes when they germinate.

Branson, Missouri micropolitan area Monoicous plants are those species that bear both sperm and eggs on the same gametophyte.

These become pollen grains, within which the microspores divide twice by mitosis to produce a very simple gametophyte.

Dioicous plants are those that have gametophytes that produce only sperm or eggs but never both.

) Generally, the terms "monoicous" and "dioicous" have been restricted to description of haploid sexuality (gametophytic sexuality), and are thus used primarily to describe bryophytes in which the gametophyte is the dominant generation.

Fossils of these plants show that they produced endosporic gametophytes, meaning that their gametophytes were not free-living as in bryophytes but developed within the spores, as in modern heterosporic vascular plants.

However, this usage, although precise, is not universal, and "monoecious" and "dioecious" are still used by some bryologists for the gametophyte.

The four-celled female gametophyte of Illicium (Illiciaceae; Austrobaileyales): implications for understanding the origin and early evolution of monocots, eumagnoliids, and eudicots.

The longer lived, more prominent autotrophic plant is the gametophyte.

Bryophytes have the most elaborate gametophytes of all living land plants, and thus have a wide variety of gametangium positions and developmental patterns.

Bryophytes have life cycles that are gametophyte dominated.

Even when capable of photosynthesis, as in mosses and hornworts, bryophyte sporophytes require additional photosynthate from the gametophyte to sustain growth and spore development and are dependent on the gametophyte for their supplies of water, mineral nutrients and nitrogen.

Both monoicous and dioicous gametophytes produce gametes in gametangia by mitosis rather than meiosis, so that sperm and eggs are genetically identical with their parent gametophyte.
