Animations and models of plant cell division are part of a new project investigating how plant cells form their distinctive walls.
Cell division is a fundamental aspect of life. Without cell division, living organisms do not grow. The last step of cell division, also called cytokinesis, is uniquely different in plants from that in animals and fungi due to the presence of cell walls in plants.
This 4D time sequence imaging from Georgia Drakakaki’s lab at UC Davis shows how new plant cell walls form between divided plant cells. Green, vesicles forming cell wall and red, cell membranes.

Within every cell is a transportation system that rivals our most complex roadways and interchanges. Known collectively as the cytoskeleton, this system is used by molecular machines called motor proteins to transport cargo throughout the cell. It’s also essential to the vital process of cell division.
