Gametogenesis/fertilization The mature gametophyte produces male or female gametes (or both) by mitosis. The male sex cell is usually small and it moves toward the immobile, larger female sex cell. The fusion of male and female gametes (fertilization) produces a diploid zygote which develops into a new sporophyte.

The Life Cycle of Plants Fertilization occurs when pollen grains (male gametophytes) are carried by the wind to the open end of an ovule, which contains the eggs, or female gametophyte. There, the pollen grain develops an outgrowth called a pollen tube, which eventually penetrates to the egg cell within one of the archegonia.

- Pine gametophyte (outside) surrounding the embryo (inside). A gametophyte is the haploid multicellular stage in the alternation of generations life cycle of plants and algae. It develops from a spore by mitotic cell division. Spores are the products of meiosis in sporophytes.Gametophytes produce haploid gametes by mitosis. In some types of plants and algae (e.g. Ulva) gametes are isogamous --that is, the gametes are all of one size, shape and general morphology.In land plants, Anisogamy is universal. As in animals, female and male gametes are called, respectively, eggs and sperm.t develops from a spore by mitotic cell division. Spores are the products of meiosis in sporophytes.

What part is the gametophyte and what part is the sporophyte of a pine tree? The ovules are the female gametophyte. In gymnosperms, pollination is the transfer of pollen from a microsporangiate, or male cone, to the micropyle of a megasporangiate, or female cone. Once fertilized the female cone produces the seed. Source(s): Conifer cones: http://en.wikipedia.org/wiki/Strobilus#C... just now. Report Abuse. The gametophyte is the male part or male for the term gamete. & sporophyte is the female part or female for the term sporo. From the pine tree, you could only specify the difference of the pines by their cones.

The Life Cycle of Plants Self-pollination-The process by which the male gametes of a plant fertilize the eggs of the same plant. Sporangium-The part of a plant where spores are produced. Spore-Haploid cell from which a gametophyte is produced. Sporophyte-A diploid plant or plant structure that produces haploid spores through meiosis. Stigma-The top part of the pistil, where pollen grains are received. Stock-Plant with a root system onto which a twig or bud from another plant (called a scion) is grafted. Tracheophyte-A terrestrial plant with a vascular system.

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.

- 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.

Flower Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy).ince the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma. The joining of the sperm to the ovules is called fertilization.

Gametangium The male gametangia are most commonly called antheridia. They produce sperm cells that they release for fertilization. Antheridia producing non-motile sperm (spermatia) are called spermatangia.

The Flower and Its Pollination In angiosperms, meiosis in the sporophyte generation produces two kinds of spores. 1  microspores. 2  which develop in the microsporangium and. 3  which will germinate and develop into the male gametophyte generation and.4  megaspores. Dioecious plants have imperfect flowers on separate plants; that is, some plants are male, some female. 2  Examples include willows, poplars, and the date palm. 3  Most dioecious plants use an X-Y system of of sex determination like that in mammals [ Link ].

Gametes: Definition, Formation, and Types Definition: Gametes are reproductive cells (sex cells) that unite during sexual reproduction to form a new cell called a zygote. Male gametes are sperm and female gametes are ova (eggs). In seed bearing plants, p ollen is the male sperm producing gametophyte.

meiosis One gamete comes from the female, and one comes from the male. Female gametes are also called eggs or ova. Female gametes are also called eggs or ova. They are created during the cellular reproduction process known as meiosis. The resulting gamete cell is a haploid cell. When the two haploid cells, the egg and sperm, fuse together during fertilization, the result is a diploid cell called a zygote. The zygote will mature into a new individual. The female gamete matures in the ovary and moves to the Fallopian tube.

Male Gamete in Plants: Definition & Concept Those male gametes that form in the anther start off as just a bunch of large nucleus-containing cells. These cells go through meiotic divisions, forming what are called tetrads, or four haploid (half chromosome) bundles of gametes. These will become pollen grains.

Gametes: Definition, Formation, and Types In animals, gametes are produced in male and female gonads. Sperm are motile and have a long, tail-like projection called a flagellum. Ova however, are non-motile and relatively large in comparison to the male gamete. Gametes are produced by a type of cell division called meiosis.They are haploid, meaning that they contain only one set of chromosomes. When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote.The zygote is diploid and contains two sets of chromosomes.efinition: Gametes are reproductive cells (sex cells) that unite during sexual reproduction to form a new cell called a zygote. Male gametes are sperm and female gametes are ova (eggs). In seed bearing plants, p ollen is the male sperm producing gametophyte.

- Pollen grains are the male gametophytes in flowering plants. Inside the pollen grain, the microspore divides to form two cells, a tube cell and a cell that will act as the sperm. Cross walls break down between each pair of microsporangia, forming two large pollen sacs.

Introduction Meiosis is not directly involved in the production of gametes because the organism that produces the gametes is already a haploid. Fertilization between the gametes forms a diploid zygote. The zygote will undergo many rounds of mitosis and give rise to a diploid multicellular plant called a sporophyte.

- Flowers are structures that perform reproductive functions. Flowering plants produce male and female cells. The male cells are called pollen and the female cells are called ova. When a flowering plant is fertilized, it produces offspring in the form of seeds. However, not all plants reproduce flowers. Simpler plants, like mosses, lack these specialized structures.
