Which of the following is NOT part of cell movement?

Cell proliferation refers to the process by which cells divide and increase in number. While this process is essential for tissue growth and repair, it does not directly involve movement of the cell itself. In contrast, cell migration, cell adhesion, and cell growth are all processes that are associated with the movement of cells.

Cell migration is the movement of cells from one location to another, which is essential in processes such as wound healing and immune responses. Cell adhesion involves the binding of cells to each other or to the extracellular matrix, which is fundamental for maintaining tissue structure and facilitating movement. On the other hand, cell growth can encompass various cellular activities, including the expansion of cell size and volume, which may indirectly facilitate movement but does not encapsulate the concept of movement as a standalone entity.

Thus, while cell proliferation is vital for the increase in cell numbers, it does not pertain to the mechanics of how cells actively move from one place to another, making it the correct choice for what is NOT part of cell movement.
