Cytokinesis in plant cells. Illustration of cytokinesis, the final stage of cell division, in a plant cell. The cell's genetic material (DNA) in the form of chromosomes (red and yellow) has separated into chromatids that have moved to opposite ends of the dividing cell, where the nuclear envelope is reforming around them. At centre, the microtubule fibres (red dashed lines) that formed the mitotic spindle are forming the phragmoplast (blue). Vesicles and other cellular material accumulate on the phragmoplast and thicken to form a cell plate which develops into a new cell wall that divides the two new cells.
