The nucleus, specifically through its regulation of gene expression, controls the production of proteins that are involved in cell movement. Additionally, the cytoskeleton plays a key role in cell movement by providing structural support and facilitating movement of organelles.
The cell membrane surrounds the cell and controls the movement of materials in and out of the cell. It is selectively permeable, allowing only certain substances to pass through.
