Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can
2024年4月12日 · Reproduction, process by which organisms replicate themselves. Reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species. Learn more about the process of reproduction in this article.

New organisms don't just appear out of nowhere—they are the result of reproduction! In this unit, we'll learn about sexual and asexual reproduction, fertilization, and development. We'll also explore mitosis and meiosis, which are the cellular processes that allow organisms to grow and reproduce.
It is possible for reproduction to be asexual, by simple division, or sexual. In sexual unicellular organisms the gametes can be produced by division (often multiple fission, as in numerous algae) or, as in yeasts, by the organism turning itself into a gamete and fusing its nucleus with that of a neighbour.
