Microfilaments and microtubules
Nuclear division plays a role in cell division.
Microfilaments
Microfilaments are solid rods about 7nm in diameter. They are also called actin filaments, because they are built from molecules called actin (a globular protein). A microfilament is a twisted double chain of actin subunits. Microfilaments are present in all eukaryotic cells. The structural role of microfilaments in the cytoskeleton is to bear tension (pulling forces). They help support/form the cells shape.
Yes, plants have microtubules. Microtubules are hollow tubes composed of a protein called tubulin. They are the thickest and most rigid of the filaments.
They Split The Cel During Cytokinesis
Microfilaments and microtubules that make up the cytoskeleton in the cell move/push the chromosomes and organelles into place for the various phases of cell division. (in metaphase, for example, they are moved to the metaphase plate (the center of the cell)) The organelles don't just randomly think "I think I'll move now." So I guess that would be the main role of microfilaments in cell division. :-)
Microfilaments assist with cell movement and are made of a protein called actin. Actin works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. Microfilaments keep organelles in place within the cell.
During cytokinesis the microfilaments form a contractile ring around the plasma membrane. The ring of filaments is equidistant from the two spindle poles, and it contracts eventually pinching the cell in two.
Actin is found in muscle tissue ( along with myosin) and makes up microfilaments which are responsible for cellular movement and also function in cell division.
Microfilaments are thin, solid protein fibers that provide structural support for eukaryotic cells.

Microfilaments assist with cell movement and also works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. They also help to hold organelles in place.
