lamella

nounPlural lamellae ləˈmɛlələˈmɛlə

1A thin layer, membrane, or plate of tissue, especially in bone.
（尤指骨组织）薄片，薄膜，瓣
Example sentencesExamples

- Several genera have well-developed dental lamellae, whereas others lack these structures.
- The first-order crossed lamellae do not become appreciably narrower toward the interior of the shell layer.
- Studies of intact animals, isolated gills, gill lamellae, and membrane vesicles have produced a variety of models of osmoregulatory ion transport in euryhaline crustaceans.

Synonyms
plate
1. 1.1Botany A membranous fold in a chloroplast.
  〔植〕（叶绿体的）片层，（真菌的）菌褶
  Example sentencesExamples
  Sections were made at distances of 200 mm, 100 mm and 40 mm from tips of an adventitious root and stained with Sudan Red 7B. Lipophilic substances such as suberin lamellae, were stained bright red.
  In chloroplasts, repair of PSII is thought to take place in the stromal lamellae.
  The enzyme randomly cleaves ß - 1,4 linked galacturonosyl residues of pectins from the middle lamella and primary cell-walls of higher plants, resulting in the maceration of plant tissues.
  The EM tilt series gave further information about the organization of lamellae within the chlorosome.
  Exodermal suberin lamellae started to develop 30 mm behind the root tip in rice and were fully developed at about 60 mm behind the tip.

Derivatives

lamellar

adjective ləˈmɛlələˈmɛlər

Michael's presentation was on ‘the use of lamellar liquid crystals as novel reaction media.’
Example sentencesExamples
- The structural preference of lipid mixtures for the lamellar or hexagonal phase is dictated by the minimization of molecular free energies of the component molecules.
- In the whole range of cholesterol concentration explored, the diffraction studies show a single lamellar phase with no evidence of a separation of extended domains.
- Cells that separated usually maintained their turgor and the separation process took place through progressive failure of middle lamellar material seen as strands between separating cells.
- The layer of polar lipid headgroups separates the apolar hydrocarbon core of the membrane from the surrounding aqueous phase and stabilizes its lamellar structure.

lamellate

adjective ˈlam(ə)lət

In addition, the plastids of these tubers were more often reported to contain a large volume of electron-dense, lamellate stroma, than were plastids of Earth-grown minitubers.
Example sentencesExamples
- Also, material from the earliest Carboniferous (early Tournasian) of France reveals a possible endosternite, gut trace and lamellate gills.
- Specifically, they lack the characteristic lamellate cortex of true rhabdites.
- They differ from Eurytholia sclerites in having marginal and ventral accretion of the lamellate shell, in their bilateral symmetry, dorsal ornament of ribs and ridges, and shell folded under a posterior apex.
- A continuous, thinly lamellate, outer region that varies in thickness overlies large expanded peg-like areas of ECM that extend from the primary wall and localize with anti-JIM7.

lamelliform

adjective

The annulus fibrosus is made of lamelliform connective tissue bands.
Example sentencesExamples
- Adrenocortical hyperplasia and adrenocortical neoplasms have pleomorphic mitochondria with tubulovesicular and lamelliform cristae and occasional inclusions.

lamellose

adjective ˈlam(ə)ləʊs

The shell surface is apparently devoid of ornament (possibly through preservation), except for the anterior margin of the trail which bears faint, irregular, undulating, and lamellose growth lines.
Example sentencesExamples
- The three known species of Loxochlamys share similar shape and micro-ornament, including a tendency to become commarginally lamellose late in ontogeny.
- Trophon sowerbyi shares the strongly lamellose shell of T. plicatus but its lamellae are much lower and the shell has a distinctly subquadrate outline.
- The main part of the shell is coarsely commarginally lamellose and lacks radial costae.
- Anoplotheca is medium-sized, with costae low and rounded, and lamellose growth lines developed.

Origin

Late 17th century: from Latin, diminutive of lamina 'thin plate'.
