planogameten.

Brit.

/ˈplanə(ʊ)ɡəˌmiːt/,

/ˌplanə(ʊ)ˈɡamiːt/, U.S.

/ˈplænoʊɡəˌmit/,

/ˌplænoʊˈɡæmˌit/

Origin: Apparently formed within English, by compounding; apparently modelled on a German lexical item. Etymons: plano- comb. form², gamete n.

Etymology: Apparently < plano- comb. form² + gamete n., apparently after a German form used by E. Strasburger (see quot. 1880 at main sense). N.E.D. (1907) gives only the pronunciation (plæ·nogămī:t) /ˈplænəʊɡəˌmiːt/.

Biology.

In algae and fungi: a motile gamete or conjugating cell. Also called zoogamete.

1886 S. H. Vines in Encycl. Brit. XX. 425/1 The zygospore is..a sexually produced spore, and the two cells which conjugate to form it are spoken of as gametes,—planogametes when they possess cilia, aplanogametes when they do not.

1942 Amer. Jrnl. Bot. 29 590/1 In Blastocladiella cystogena the thallus produces only resting sporangia and uniciliated spores, which after encystment give rise to isogamous planogametes.
