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.

Microfilaments and microtubules
Microfilaments are responsible for providing structural support and maintaining cell shape. They also play a key role in cell movement, such as muscle contraction and cell division. Additionally, microfilaments are involved in intracellular transport and cellular signaling.
Microfilaments are important because they play a key role in cell structure and movement. They are involved in maintaining cell shape, cell division, and cell migration. Microfilaments are also crucial for various cellular processes such as muscle contraction and cell signaling.

Microfilaments
The cytoskeleton is composed of microfilaments (actin filaments) and microtubules. These components provide structure and support to cells, as well as playing a role in cell movement and intracellular transport.
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 are well known for their role in cell movement and shape changes, such as in cell division, muscle contraction, and cell migration. They are also involved in maintaining cell structure and providing mechanical support.
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.
