agameten.

Brit.

/eɪˈɡamiːt/, U.S.

/eɪˈɡæmˌit/

Origin: A borrowing from German. Etymon: German Agamete.

Etymology: < German Agamete (M. Hartmann 1904, in Biol. Centralbl. 24 24) < a- a- prefix⁶ + Gamete gamete n. Compare ancient Greek ἄγαμος unmarried (see agamous adj.).

Biology.

1. A stage in the life cycle of a protozoan which functions as a non-sexual reproductive cell.

ΚΠ

1910 Jrnl. Med. Res. 23 492 The schizonts (agametes), or those forms which show no sexual differentiation and in which multiplication is not preceded by sexual union, are devoid of any characteristic granules.

1940 L. H. Hyman Invertebrates I. iii. 144 The growing vegetative parasite is called a trophozoite. When this..undergoes multiple fission directly into agametes, it is called a schizont or agamont.

1965 J. I. Poljanskij & E. M. Chejsin tr. V. A. Dogiel Gen. Protozool. (ed. 2) viii. 442 The number of agametes produced corresponds to the number of generative nuclei.

2000 K. Mikami in J. J. Tarín & A. Cano Fertilization Protozoa & Metazoan Animals i. 13 All three gamete nuclei are thought to undergo meiosis and produce 12 nuclei, which results in the formation of 12 agametes.

2. A non-sexual reproductive cell in a mesozoan.
