Reproductive Organ

 

in plants and animals an organ that performs the functions of giving rise to offspring. In many lower plants and in all higher plants the cycles of development involve alternation of nuclear phases, leading to alternation of asexual (sporophyte) and sexual (gametophyte) generations. In such plants the reproductive organs are represented by organs of asexual reproduction, known as sporangia (microsporangia and megasporangia), and by organs of sexual reproduction (gametangia). In plants the reproductive organs also include organs of vegetative reproduction. For a discussion of the reproductive organs of animals seeSEXUAL ORGANS and REPRODUCTION.
