Exempel på hur man kan använda CONCEPTACLES i en mening

• Bifurcariopsis reproduces by means of conceptacles; it produces tetraspores and dispores and carpospores.
• As presently defined, Cystoseira comprises fucoids characterised by antherozoids without stigmata, few antheridial branches, trichothallic hairs in conceptacles, large ovoid oospheres, and eggs that remain attached to the surface of the receptacles through mucilaginous stalks until after fertilization.
• de Réaumur gave an account of Fucus in which he noted the two types of external openings in the thallus: the non-sexual cryptostromata (sterile surface cavities) and the conceptacles (fertile cavities, immersed but with a surface opening) containing the sexual organs, which he thought were female flowers.
• Similar structures also exist: cryptostomata are similar to conceptacles but differ having only hairs and are sterile; caecostomata, are found only in Fucus distichus, in these the ostiole becomes blocked during development.
• Choreonema reproduces by means of conceptacles; it produces tetraspores and dispores and carpospores.
• In all bed bug species except Primicimex cavernis, sperm are injected into the mesospermalege, a component of the spermalege, Injected sperm travel via the haemolymph (blood) to sperm storage structures called seminal conceptacles, with fertilisation eventually taking place at the ovaries.
• Calliarthron reproduces by means of conceptacles; it produces tetraspores, dispores and carpospores.
• The sperm are received by the mesospermalege and eventually reach the spermathecae, also referred to as seminal conceptacles.
• Female gametangia are present throughout the year, and they develop either on branched or unbranched stalks within the conceptacle, or directly from the walls of conceptacles.
• These algae are dioecious, with domed spermatangial conceptacles, carpogonial conceptacles and carposporangial conceptacles.
• Crustaphytum goes through the triphasic life cycle, a character of the phylum Rhodophyta, and all of its reproductive structures are protected by specialized conceptacles, sac-like structures that are situated in the receptacle.
• The carposporangial conceptacles have a warty surface and are more oblong, and the carposporangia themselves have superficial gonimoblast filaments.
