Reproduction
Re`pro*duc"tion\ (-d?k"sh?n), n. [Cf. F. reproduction.]1. The act or process of reproducing; the state of being reproduced; specifically (Biol.), the process by which plants and animals give rise to offspring. Note: There are two distinct methods of reproduction; viz.: asexual reproduction (agamogenesis) and sexual reproduction (gamogenesis). In both cases the new individual is developed from detached portions of the parent organism. In asexual reproduction (gemmation, fission, etc.), the detached portions of the organism develop into new individuals without the intervention of other living matter. In sexual reproduction, the detached portion, which is always a single cell, called the female germ cell, is acted upon by another portion of living matter, the male germ cell, usually from another organism, and in the fusion of the two (impregnation) a new cell is formed, from the development of which arises a new individual. 2. That which is reproduced.

| reproduction (rē'prə-dŭk'shən) Pronunciation Key
The process by which cells and organisms produce other cells and organisms of the same kind. ◇ The reproduction of organisms by the union of male and female reproductive cells (gametes) is called sexual reproduction. Many unicellular and most multicellular organisms reproduce sexually. ◇ Reproduction in which offspring are produced by a single parent, without the union of reproductive cells, is called asexual reproduction. The fission (splitting) of bacterial cells and the cells of multicellular organisms by mitosis is a form of asexual reproduction, as is the budding of yeast cells and the generation of clones by runners in plants. Many plants and fungi are capable of reproducing both sexually and asexually, as are some animals, such as sponges and aphids. |
