Oophyte \O"["o]*phyte\, n. [Gr. w,'o`n an egg + fyto`n a plant.]
   (Bot.)
   Any plant of a proposed class or grand division (collectively
   termed o["o]phytes or O["o]phyta), which have their sexual
   reproduction accomplished by motile antherozoids acting on
   o["o]spheres, either while included in their o["o]gonia or
   after exclusion.

   Note: This class was at first called {O["o]spore[ae]}, and is
         made to include all alg[ae] and fungi which have this
         kind of reproduction, however they may differ in all
         other respects, the contrasted classes of Thallophytes
         being Protophytes, Zygophytes, and Carpophytes. The
         whole system has its earnest advocates, but is rejected
         by many botanists. See {Carpophyte}.
