- A gonad or sex gland or reproductive gland is an endocrine gland that produces the gametes (germ cells) of an organism. In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes, are haploid germ cells.

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.

Gametogenesis is? Animals produce gametes directly through meiosis in organs called gonads (testicles in males and ovaries in females). Males and females of a species that reproduces sexually have different forms of gametogenesis.

CH. 22 Plant Growth, Reproduction, and Response 4 The gamete-producing plant is the mature GAMETOPHYTE gametophyte phase is HAPLOID begins with spore gametes produced through mitosis. A SPORE is the beginning of the HAPLOID PHASE of the plant life cycle. A spore divides by mitosis and grows into a mature GAMETOPHYTE (gamete-producing plant).

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 (bryophytes) the gametophyte is the commonly known phase of the plant.

What type of cell division produces gametes? Answered by The Community. Making the world better, one answer at a time. Meiosis is a type of cell division that produces gametes. In meiosis, the process of PMAT occurs twice, producing four genetically different cells instead of two identical ones.

- Pollen grains (from the greek palynos for dust or pollen) contain the male gametophyte (microgametophyte) phase of the plant. Pollen grains are produced by meiosis of microspore mother cells that are located along the inner edge of the anther sacs (microsporangia).ngiosperm male gametophytes have two haploid nuclei (the germ nucleus and tube nucleus) contained within the exine of the pollen grain (or microspore). Female gametophytes of flowering plants develop within the ovule (megaspore) contained within an ovary at the base of the pistil of the flower.

- The primary sex organ of a male is the testis. The testis is the reproductive gland of males. It produces spermatozoa and the androgens.

Where are gametes produced? Gametes are produced in the gonads. The male gamete, sperm, is produced in the testes.The female gamete, egg, is produced in the ovaries. All gametes are formed by a process called meiosis.

Female Reproductive System The primary follicles located in the ovary contain the only cells in the female that can complete the special form of cell division (meiosis) that produces gametes. In females the mature gametes are called egg cells or ova.

- The gametophyte is the gamete-producing plant that produces male reproductive structures called antheridia, which produce sperm, and female reproductive structures called archegonia, which produce eggs. When a sperm cell fertilizes an egg inside the archegonium, a diploid zygote is formed.lso, without an extensive means of internal transport, nonvasculars lack true roots, stems or leaves and tend to be small, inconspicuous plants. Finally, these plants are gametophyte dominant, meaning that the recognizable stage of these plants is the haploid gametophyte generation.

Where are gametes produced? Best Answer: gametes, or sex cells, are created in the testes(male) or in the ovaries (female), males are constantly making new gametes while females have them all when they are born and do not make anymore. Source(s): Tim · 5 years ago.

Gonad Gonad: Gonad,, in zoology, primary reproductive gland that produces reproductive cells (gametes). In males the gonads are called testes; the gonads in females are called ovaries. (see ovary; testis). The gonads in some lower invertebrate groups (e.g., hydrozoans) are temporary organs; in higher forms they are permanent.

The Reproductive System Separate pages describe the male reproductive system and the female reproductive system. 1  The reproductive systems of both sexes share the same basic organization: The gonads produce gametes (eggs or sperm) which unite during fertilization. 2  The creation of gametes is called gametogenesis. The process follows the same general sequence in both males and females: Gamete production begins with germ cells, which begin to develop and multiply in the embryo. They are diploid cells, containing 23 pairs of chromosomes for a total of 46 chromosomes.

- The production of female gametes that occurs in the ovary is called oogenesis. Oogenesis. The process by which female gametes develop is called oogenesis. The female stem cells that produce the gametes are called oogonia (sing. oogonium). During development of the embryo these stem cells migrate into the ovary.

What's the name for the reproductive cells that make gametes? Cell that functions in sexual reproduction by merging with another gamete to form a zygote. Examples of gametes include sperm and egg cells.In most organisms, the gametes are haploid (they contain half the number of chromosomes of the parent), owing to reduction division or meiosis.In higher organisms, gametes are of two distinct types: large immobile ones known as eggs or egg cells (see ovum) and small ones known as sperm.n most organisms, the gametes are haploid (they contain half the number of chromosomes of the parent), owing to reduction division or meiosis.

- The gametes, formed by meiosis in the sexorgans, or gonads —the testes and ovaries —are haploid(see chapter 12). The process of spermatogenesis (spermformation) and oogenesis (egg formation) will be de-scribed in later sections. For a more detailed discussionof asexual and sexual reproduction, see chapter 12.

Gametogenesis/fertilization The male and female reproductive cells (gametes = sex cells) develop from the meiocytes through post-meiotic differentiation in both animals and plants. The male sex cells are called sperm cells (from the Greek sperma = seed), the female are named egg cell or ovum (the latin word for egg).

Gametophyte 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.
