Etymology[edit]

Ancient Greek

Noun[edit]

blastophore (plural blastophores)

  1. (biology, obsolete) That portion of the spermatospore which is not converted into spermatoblasts, but carries them.
    • 1880, Journal of Microscopy[1], volume 3:
      It does not, however, happen that the whole spermatosphere is converted into spermatoblasts; there remains a passive portion, which in the earthworm occupies a central position; this is the "sperm-blasophore," or "blastophoral cell."
    • 1906, W. M. Smallwood, “Notes on Branchiobdella”, in The Biological Bulletin[2], page 106:
      Associted with the formation of the male sex cells from the time they leave the testes until the spermatozoön becomes fully grown there is a protoplasmic structure, termed the blastophore (Bloomfield, '80, Calkins, '95) in Lumbricus, and the cytophore (Voigt, '85) in Branchiobdella varians.
    • 1916, F. J. Meggitt, “A new species of tapeworm from a parakeet, Brotogerys tirica”, in Parasitology[3], volume 8, page 50:
      The cytophore now splits internally in such a way as to separate an inner sphere (blastophore) from an outer envelope.
