Noun
phragmoplast (plural phragmoplasts)
(biology) A structure that forms in plant cells during late cytokinesis and serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells.
The phragmoplast is a microtubule structure typical for higher plants, whereas some green algae use a phycoplast microtubule array during cytokinesis. Source: Internet
In plants, this structure coalesces into a cell plate at the center of the phragmoplast and develops into a cell wall, separating the two nuclei. Source: Internet
