gamete Define reproductive cell. reproductive cell synonyms, reproductive cell pronunciation, reproductive cell translation, English dictionary definition of reproductive cell. A cell whose nucleus unites with that of a cell of the opposite sex to form a new organism. A reproductive cell contains only a single (haploid) set of chromosomes. Animal egg and sperm cells, the nuclei in grains of pollen, and egg cells in plant ovules are all reproductive cells. Also called gamete, sex cell. See Note at mitosis.

Gametes: Definition, Formation & Fusion Definition of Gametes. Gametes are the reproductive cells used during sexual reproduction to produce a new organism called a zygote. The gametes in males and females are different. The male gamete is called sperm. It is much smaller than the female gamete and very mobile.ametes are the cells used during sexual reproduction to produce a new individual organism or zygote. The male gamete, sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova. Both sperm and egg are only haploid cells. They only carry half of the chromosomes needed.

Somatic cells Somatic cells. Definition. noun, singular: somatic cell. The word “somatic” is derived from the Greek word soma, meaning “body”. Hence, all body cells of an organism – apart from the sperm and egg cells, the cells from which they arise (gametocytes) and undifferentiated stem cells – are somatic cells.

Somatic Cells: Definition, Examples & Types All living creatures are made up of cells. In plants and animals, there are two major categories of cells: somatic cells and reproductive cells, known as germ cells or gametes. In humans and other animals, they are the egg and sperm cells. All other cells in the body are somatic cells.

Daughter Cells Daughter Cells. Daughter cells are cells that result from the division of a single parent cell. They are produced from the division processes of mitosis and meiosis. Cell division is the reproductive mechanism, whereby living organisms grow, develop, and produce offspring. At the completion of the mitotic cell cycle, a single cell divides forming two daughter cells.

egg The mature reproductive cell of female animals. The nucleus of an egg is capable of fusing with the nucleus of a sperm (the male reproductive cell) to form a new organism. In many species, eggs are produced by the ovaries. An egg carries half as many chromosomes as the other cells of the body. Also called ovum.

- Somatic cell. A somatic cell is generally taken to mean any cell forming the body of an organism. Somatic cells, by definition, are not germline cells. In mammals, germline cells are the sperm and ova (also known as gametes) which fuse during fertilization to produce a cell called a zygote, from which the entire mammalian embryo develops.

Introduction to Cell Reproduction Germ cells are different from somatic cells in a critical way. Whereas somatic cells are diploid, meaning they have two copies of each chromosome, germ cells are haploid. The haploid nature of germ cells is vital to the process of sexual reproduction. There are two different sex cells or gametes: sperm and eggs. Males produce sperm and females produce eggs.

meiosis Noun. 1. meiosis - (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants). miosis, reduction division.he first phase of meiosis involves duplication and then separation of the chromosomes, followed by division into two daughter cells that each contain half the number of chromosomes as the original cell.

spore A reproductive cell or group of cells, produced by some plants, that is capable of developing into an adult plant without combining with another reproductive cell. Plants also produce sperm cells. The spores of nonflowering plants are analogous to the seeds of flowering plants.

How and which type of cells undergo mitosis? Somatic cell. A somatic cell (Greek: σὠμα/soma = body) or vegetal cell is any biological cell forming the body of an organism; that is, in a multicellular organism, any cell other than a gamete, germ cell, gametocyte or undifferentiated stem cell.

How Is Cloning Done? Let's take it apart: Somatic cell: A somatic cell is any cell in the body other than sperm and egg, the two types of reproductive cells. Reproductive cells are also called germ cells. In mammals, every somatic cell has two complete sets of chromosomes, whereas the germ cells have only one complete set.n SCNT, the egg cell's single set of chromosomes is removed. It is replaced by the nucleus from a somatic cell, which already contains two complete sets of chromosomes. So, in the resulting embryo, both sets of chromosomes come from the somatic cell.

gamete 1. one of two haploid reproductive cells, male (spermatozoon) and female (oocyte), whose union is necessary in sexual reproduction to initiate the development of a new individual.

- The ultimate function is to divide reproductive cells while cutting the number of chromosomes by half. To do this, two divisions occur instead of one. The number of chromosome … s must be halved from 46 to 23 because reproductive cells will combine to make a complete set of 46.

Egg cell The egg cell, or ovum, is the female reproductive cell (gamete) in oogamous organisms. The egg cell is typically not capable of active movement, and it is much larger (visible to the naked eye) than the motile sperm cells. When egg and sperm fuse, a diploid cell (the zygote) is formed, which rapidly grows into a new organism.

- Ovum. (ō`vəm) , in biology, specialized plant or animal sex cell, also called the egg, or egg cell. It is the female sex cell, or female gamete; the male gamete is the sperm spermor spermatozoon, in biology, the male gamete (sex cell), corresponding to the female ovum in organisms that reproduce sexually.n higher animals the ovum differs from the sperm in that it is larger and is nonmotile, a smooth sphere or oval lacking the flagellum of the sperm.

The Difference Between Body Cells & Primary Reproductive Cells Organisms that reproduce sexually produce sex cells, or gametes, that carry a single set of chromosomes, the haploid number for the species. In contrast, body, or somatic, cells are the regular cells that form the organism’s tissues and organs. Somatic cells of sexual organisms have the diploid number of chromosomes, one set from each parent. Both cell types undergo mitosis, but only the primary reproductive cells, or gametocytes, also undergo meiosis.

Egg cell Ovum redirects here. It is not to be confused with Ovule. The egg cell, or ovum, is the female reproductive cell (gamete) in oogamous organisms. The egg cell is typically not capable of active movement, and it is much larger (visible to the naked eye) than the motile sperm cells. When egg and sperm fuse, a diploid cell (the zygote) is formed, which gradually grows into a new organism.

Begotten Not Made: A Catholic View of Reproductive Technology In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.
