What's the difference between chlamys and perianth?

Chlamys


Definition:

  • (n.) A loose and flowing outer garment, worn by the ancient Greeks; a kind of cloak.

Example Sentences:

  • (1) The six main carotenoids extracted from three shellfish species (Chlamys opercularis, L., Cardium tuberculatum, L., Pecten jacobaeus, L.) were isolated in highly pure form by means of semi-preparative HPLC.
  • (2) A binary complex consisting of Mr 19,000 and Mr 40,000 components was co-purified with troponin from a crude troponin fraction of Akazara scallop (Chlamys nipponensis akazara) striated adductor muscle.
  • (3) Bioaccumulation factor (BF) for endosulfan II for crayfish tissues was 1.97, which is considerably lower than for other aquatic invertebrates (26 for scallop, Chlamys opercularis and 600 for mussel, Mytilus edulis.
  • (4) Three components of Akazara scallop (Chlamys nipponensis akazara) troponin were well separated from each other by a single-step chromatography on CM-Toyopearl, although they were hardly separated on DEAE-Sephadex A-25.
  • (5) Here we report two related compounds, 1-methyl-N alpha-methyl-4-mercaptohistidine, or ovothiol B, from the scallop Chlamys hastata, and 1-methyl-4-mercaptohistidine, or ovothiol A, from the starfish Evasterias troschelii.
  • (6) Troponins which confer Ca-sensitivity to skeletal actomyosin ATPase were successfully isolated from striated and smooth adductor muscles of "Akazara" scallop (Chlamys nipponensis akazara).
  • (7) The putative larval form which is morphologically dissimilar is found in two species of marine molluscs, Chlamys bifrons and Pecten albus.
  • (8) Troponin was isolated from striated adductor muscles of the "Akazara" scallop (Chlamys nipponensis akazara), and purified in an active form by DEAE-cellulose (Whatman DE52) column chromatography and subsequent gel filtration on Sephacryl S-300.
  • (9) Marine bivalve molluscs, the mussel Mytilus galloprovincialis aud the scallop Chlamys (Flexopecten) glaber ponticus, have been injected (intramuscularly or in the haemolymph) with glucose, mammalian insulin, insulin (or insulin-like substance) from molluscs, and anti-insulin serum, checking changes in glucose and fatty acid content of the haemolymph as well as in the content of glycogen and the activity of glycogen synthetase in muscles.

Perianth


Definition:

  • (n.) The leaves of a flower generally, especially when the calyx and corolla are not readily distinguished.
  • (n.) A saclike involucre which incloses the young fruit in most hepatic mosses. See Illust. of Hepatica.

Example Sentences:

  • (1) In contrast, mutations in another floral homeotic gene, APETALA2 (AP2), result in the replacement of the perianth organs by the reproductive organs.
  • (2) In ag mutants, the loss of AG function leads to the conversion of these organs to the perianth organs (petals and sepals).
  • (3) The proper time to pick the flower buds comes when they are fully developed before the perianth appears.
