    • 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.
    • The symplastic path is mediated by plasmodesmata which bridge the cell walls between adjacent cells so that a cytoplasmic continuum is formed.
    • 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.
