  • These sterile cells rise up from the conceptacle floor to form a peak.
  • These sterile cells, which are structurally distinct from the basidia, are further classified according to their position.
  • The sporogonium has a small foot, but the sterile cells among the spores do not develop into elaters. Cited from Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3
  • G. clavatus does not contain cystidia, the sterile cells associated with basidia in many species.
  • The sterile cells may form a central support structure or surround the spermatogenous tissue as a protective jacket.
  • The structure supports a central semi-powdery mass made of spores, sterile cells and balls of conidia.
  • She can entrust the egg to sterile cells, without provisions fit to use; she can establish several in the same cell, though this cell contains nourishment for one only. Cited from The Mason-Bees, by J. Henri Fabre
  • These cells are surrounded by a wall of sterile cells called the tapetum, which supplies food to the cell and eventually becomes the cell wall for the pollen grain.
  • Paraphyses are sterile cells' often with swollen tips and are at high turgor pressure.
  • In the higher forms a sterile foot and seta is present, and sterile cells or elaters occur with the spores. Cited from Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3
  • The sporogonium even in the simplest forms has a sterile foot, but in this series also the origin of elaters from sterile cells can be traced. Cited from Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3
  • They radiate out from a small plug of sterile cells projecting into the base of the capsule, and some are attached to this, while others lie free among the spores. Cited from Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3
  • An antheridium typically consists of sterile cells and spermatogenous tissue.
  • Interspersed among the basidia are sterile cells called cystidia.
  • These are sterile cells extending down from the upper portion of the cavity inside sexual structures containing the sac-like asci with sexually produced spores (ascospores).
  • The spore-bearing hymenium, the outermost layer of cells, contains asci interspersed with sterile cells called paraphyses.
  • Microscopically, sterile cells, long-threaded cells called capillitium originate from the inner surface of the peridium; they are highly branched and interwoven.
  • These spores are reddish brown, smoothly rounded, and they tend to be in clumps of 5-6 with sterile cells around them.
  • The paraphyses (sterile cells interspersed amongst the asci) are cylindrical, simple or branched.
  • Coleochaete also has a sterile jacket of cells that surround the gametangia, and zygotes that are protected by a layer of sterile cells after fertilization.
