WebApr 28, 2024 · Motility Definition. Motility is the ability of a cell or organism to move of its own accord by expending energy. Means of motility can range from animals’ use of muscles to single cells which may have microscopic structures that propel the cell along. Most animals are motile, using means such as walking, slithering, swimming, and flying … WebThe cytoskeleton is a dynamic network of protein filaments that defines the structure and motility of the cell (Figure 2 ). It prevents deformation of the cell, while allowing for cell-mediated changes in structure including contraction and cell migration. The cytoskeleton is involved in cellular signaling and mediates chromosome segregation ...
