A multinucleated cell that has formed by fusion of separate cells.
[sym- + G. plastos, formed]
that part of a plant consisting of the PLASMALEMMA and the cytoplasm contained within the plasmalemma, outside which is the APOPLAST (2). The symplastic organisation enables symplastic transport between live cells, via PLASMODESMATA.
The Hexactinellida, for example, are mostly syncytial (Reiswig, 1979; Mackie and Singla, 1983), a condition that allows symplastic transport of food (Perez, 1996; Wyeth et al., 1996) and rapid conduction of action potentials that control the feeding current (Leys and Mackie, 1997).
