Definition of plasmalemma in English:

plasmalemma

noun

Biology
  • A plasma membrane which bounds a cell, especially one immediately within the wall of a plant cell.

    • ‘Folding of the plasmalemma and the formation of multiple small vesicles between the cell wall and the plasmalemma were observed.’
    • ‘Net glucose loss from live cells would have been limited by the intact plasmalemma, cell metabolism and simultaneous glucose uptake.’
    • ‘The unstained region around the periphery of most cells was almost certainly an artefact of plasmolysis, indicated by occasional contact points between plasmalemma and cell wall plasmodesmata.’
    • ‘A mechanosensitive Ca 2 + channel is shown linking the cell wall to the plasmalemma so that relative movement between them, or between the former and the cytoskeleton, could open the channel.’
    • ‘It is, therefore, most unfortunate that little is known of them except that they appear to be gated by tension and link the cell wall to the plasmalemma and possibly the cytoskeleton.’

Origin

1920s: from plasma + Greek lemma ‘rind’.
