plasmodesma

noun

Botany
  • A narrow thread of cytoplasm that passes through the cell walls of adjacent plant cells and allows communication between them.

    • ‘Plant learning increases vasculature and increased communication between cells through plasmodesmata.’
    • ‘The symplastic path is mediated by plasmodesmata which bridge the cell walls between adjacent cells so that a cytoplasmic continuum is formed.’
    • ‘Hence, stromules may possibly be considered as organellar analogues of plasmodesmata, the cytoplasmic connections that join plant cells in many tissues.’
    • ‘It may traverse the root either through the cytoplasm of cells linked by plasmodesmata (the symplast) or through the spaces between cells (the apoplast).’
    • ‘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.’

Origin

Early 20th century: from German Plasmodesma, from late Latin plasma ‘mould, formation’ + Greek desma ‘bond, fetter’.
