The phragmoplast is a plant cell structure that forms during cytokinesis, the final stage of cell division, specifically in the formation of the cell plate. This structure consists of microtubules and is crucial for guiding the assembly of new cell walls between dividing daughter cells. In green algae, which are precursors to land plants, the presence of the phragmoplast highlights the evolutionary link between these groups and reflects their shared mechanisms of growth and division.
congrats on reading the definition of phragmoplast. now let's actually learn it.
