plasmodesma
/ˌplazmə(ʊ)ˈdɛzmə
/noun (plural plasmodesmata /ˌplazmətə(ʊ)ˈdɛzmə/) Botany
A narrow thread of cytoplasm that passes through the cell walls of adjacent plant cells and allows communication between them.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....
- Plant learning increases vasculature and increased communication between cells through plasmodesmata.
- Hence, stromules may possibly be considered as organellar analogues of plasmodesmata, the cytoplasmic connections that join plant cells in many tissues.
Origin
Early 20th century: from German Plasmodesma, from late Latin plasma 'mould, formation' + Greek desma 'bond, fetter'.
