A membranous sac that, in cell division, is the precursor to the plant cell wall.
Flattened membrane-bounded structure that forms from fusing vesicles in the cytoplasm of a dividing plant cell and is the precursor of the new cell wall.
In plants, a membrane-bound space produced during cytokinesis by the vesicles of the Golgi apparatus. The cell plate fuses with the plasma membrane, dividing the cell into two compartments.
