BRAINCAKECell Movement
Movement of cells is through actin fibres in the cytoskeleton.
The filament lengths can be changed in one direction by the addition of subunits in the required direction.
This leads to the cell membrane being pushed out and the flow of cytoplasm and the cell contents in one direction.
