Biology Prefixes and Suffixes: (gam-, gamo-, or -gamy)


The affix (gam-, gamo-, or -gamy) refers to a joining, marriage, or sexual union.

Biology Prefixes and Suffixes: (-gam- or gamo-)


Agamete (a-gam-ete) - organisms, such as bacteria, that reproduce asexually by fission without the production of gametes.

Gametangia (gam-et-angia) - organs or cells in which gametes are produced. They are found organisms such as plants, algae and fungi.

Gametes (gam-etes) - egg or sperm cells that unite during sexual reproduction.

Gametocyte (gam-eto-cyte) - a cell from which gametes develop by meiosis, particularly a spermatocyte or an oocyte.

Gametogenesis (gam-eto-genesis) - process involving the formation and development of gametes.

Gametophore (gam-eto-phore) - a plant structure that bears reproductive organs such as gametangia.

Gametophyte (gam-eto-phyte) - the sexual phase in plants and other organisms that undergo alternation of generations. Gametes are produced in this phase.

Gamic (gam-ic) - relating to or derived from a sexual union.

Gamogenesis (gamo-genesis) - sexual reproduction.

Gamophobia (gamo-phobia) - an irrational fear of getting married or being in a committed relationship.

Biology Prefixes and Suffixes: (-gamy)


Anisogamy (an-iso-gamy) - a type of heterogamy in which gametes of different forms or sizes unite.

Apogamy (apo-gamy) - a form of asexual reproduction in which a female gamete or egg cell develops into an individual without fertilization.

It is also called parthenogenesis.

Autogamy (auto-gamy) - self-fertilization.

Bigamy (bi-gamy) - marriage to two persons at the same time.

Dichogamy (dicho-gamy) - the maturation of male and female parts of a flower at different times so as to prevent self-pollination.

Digamy (di-gamy) - a second marriage after the termination of the first marriage by divorce or death.

Endogamy (endo-gamy) - internal fertilization between gametes that share the same genetic ancestry. It also refers to the restriction of marriage to individuals within the same culture or social unit.

Exogamy (exo-gamy) - the union of gametes from organisms that are not closely related, as in cross pollination. It also means to marry outside of ones culture or social unit.

Herkogamy (herko-gamy) - the prevention of self-pollination in plants due to structural obstacles. The male anther and female stigma are arranged so as to prevent pollen transfer from the male portion to the female portion of flowers on the same plant.

Heterogamy (hetero-gamy) - a type of alternation of generations seen in some organisms that alternate between a sexual phase and a parthenogenic phase. Heterogamy can also refer to a plant with different types of flowers or a type of sexual reproduction involving two kinds of gametes that differ in size.

Isogamy (iso-gamy) - the union of sex cells that are identical in form and size.

Karyogamy (karyo-gamy) - uniting of cell nuclei, as in fertilization.

Xenogamy (xeno-gamy) - cross-pollination between flowers on genetically different plants. It also means to marry outside of ones culture or social unit.
