- The female gametophyte in an angiosperm is the pistil. This is completely wrong. The male gametophyte consists of the ge … nerative cell and the tube cell in the pollen grain. The female gametophyte is the 7-celled 8 nucleate embryo sac. 3 people found this useful.

Ovule The female gametophyte—specifically termed a megagametophyte—is also called the embryo sac in angiosperms. The megagametophyte produces an egg cell (or several egg cells in some groups) for the purpose of fertilization. After fertilization, the ovule develops into a seed.

Where are gametes found? Report Abuse. Found in the reproductive organs the gametes are haploid cells (26 chromosomes as opposed to 46(diploid)) which means that they are sex cells. These gametes fuse with other gametes to create fertilisation.Female Gamete=Egg Male Gamete=Sperm these are found in the reproductive organs.est Answer: Gametes are reproductive cells. They contain a haploid set of chromosomes (a half set). In animals they are sperm and egg. I'm not sure about plants but I think most contain both male and female parts for reproduction which results in a seed.

Sporophyte Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition. The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte. Because this embryo-nurturing feature of the life cycle is common to all land plants they are known collectively as the Embryophytes.

- As was true in the gymnosperms, the main plants in angiosperms are sporophytes, while the gametophytes are confined to the flowers, usually male and female together. Male gametophytes are called stamens, female gametophytes are pistils.

Sporophyte In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and embryo sac. Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition.The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte.he sporophyte produces spores (hence the name) by meiosis, a process also known as reduction division that reduces the number of chromosomes in each spore mother cell by half. The resulting meiospores develop into a gametophyte.

Homology in the Alternation of Generations 1 The female gametophyte remains inside the female megasporangium, which is surrounded by sporophyte integuments. 2  This structure is known as an ovule. 3  Eventually, after the ovum is fertilized and becomes a zygote, the ovule will become a seed.4  The outer covering, the seed coat is derived from sporophyte tissue.he Gametophyte of the Anthophyte. You saw the cherry tree above. To see the gametophytes, we need to examine that structure unique to the Anthophytes, the flower. 1  The microsporophylls are the stamens, each tipped by the anther, which contains the diploid cells that will divide to become microspores.

Gametogenesis The sexual generation of the plant, the haploid gametophyte, develops from the spores, and it is in the sex organs of the gametophyte, the gametangia (male, anther; female, archegonium), that gametogenesis takes place by means of mitoses.ametogenesis. the process of development and formation of the sex cells, or gametes. The gametogenesis of the male gametes (spermatozoids, sperms) is called spermatogenesis; and that of the female gametes (the egg cells), oogenesis.

What is the difference between the archegonium and antheridium? Diagram of antheridium anatomy. An antheridium or antherida (plural: antheridia) is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm). It is present in the gametophyte phase of cryptogams like bryophytes and ferns, and also in the primitive vascular psilotophytes.n bryophytes, the antheridium is borne on an antheridiophore, a stalk-like structure that carries the antheridium at its apex. In many gymnosperms and all angiosperms, the male gametophytes have been reduced to pollen grains and their antheridia have been reduced to a single generative cell within the pollen grain.

The gametophyte is found where in flowering plants? The gametophyte produces male or female gametes (or both), in a process called mitosis. The fusion of male and female gametes produces a zygote which develops into the sporophyte.

In mosses, the gametophyte is the dominant generation, while the sporophytes consist of sporangium-bearing stalks growing from the tips of the gametophytes.

- In the anther, microspores divide and develop into male gametophytes, but the male gametophyte is only two cells. One of these two cells, the generative cell, produces two sperm. The other cell, the tube cell, produces the pollen tube that sperm travel down to reach the female gametophyte.

Reproduction in Plants The male gametophyte is the mature pollen grain. Pollen is produced in the anthers, which are attached at the distal end of filaments. The filament and anther together constitute the stamen, the male sex organ. Flowers usually produce many stamens just inside of the petals.

A gametophyt … e is the part of the plant that is responsible for creating gametes AKA sexual reproductive cell (sperm or egg).he reproductive structure of a gymnosperm is the cone. The cone produces pollen or sperm cells that will later on fertilize a female plants eggs or anthers.

The Life Cycle of Plants Angiosperm Fertilization. The female reproductive organ of angiosperms is the pistil, located in the middle of the flower. As in gymnosperms, the male gametophyte is the pollen grain. In order for fertilization to occur in most flowering plants, insects or other animals must transport the pollen to the pistil.

Antheridium Female gametangia are called archegonia; male gametangia, antheridia. At maturity, archegonia each contain one egg, and antheridia produce many sperm cells. Because the egg is retained and fertilized within the archegonium, the early stages of the developing sporophyte are protected and nourished by the gametophytic tissue.

- In bryophytes (mosses, liverworts, and hornworts), the gametophyte represents the longer lived, nutritionally independent and more visible stage of the life cycle. Sporophytes are typically attached to and dependent on gametophytes. Moss gametophytes originate from the germination of a spore.

- The male gametophytes, called microgametophytes, are produced in anther sacs in the anthers of the flower's stamens. Like the male gametophytes of the gymnosperms, the sperm is encased in a protective cover and this complex is called a pollen grain.hese protonemas produce gametophytes, small leafy plants, male and female. It is these gametophytes, the leafy plants, which we typically associate with mosses. Sperm is produced within the antheridium of the male gametophyte, eggs are found in the female gametophyte's archaegonium.

- The moss sporophyte depends on the gametophyte and is not a free‐living independent plant. The spores form after meiosis and germinate to develop into male or female gametophytes. Moss sperm are produced from cells in the antheridia of the male gametophyte.The moss eggs are located at the base of the archegonia, on the female gametophyte. Each sperm has two flagella.Sperm swim to the eggs and after fertilization, the zygote develops into the sporophyte.oss sperm are produced from cells in the antheridia of the male gametophyte.

Gametophyte In the gametophyte phase, male and female organs (gametangia) develop and produce eggs and sperm (gametes), which unite in fertilization (syngamy). The fertilized egg (zygote) develops into the sporophyte phase, which produces numerous unicellular spores. These, in turn, develop directly into new gametes.

Flowering plant Reduced male parts, three cells. The male gametophyte in angiosperms is significantly reduced in size compared to those of gymnosperm seed plants. The smaller size of the pollen reduces the amount of time between pollination — the pollen grain reaching the female plant — and fertilization.

How does the male gamete reach the female gamete in plants? The female gamete of the plant is the ovule, which is found in the ovary. + The male gamete of the plant is the pollen grain, produced by the anthers.
