Cell movement refers to the ability of cells to change their position or migrate from one location to another. This process is essential for various biological functions, including development, immune responses, and wound healing. Cells can move through mechanisms such as amoeboid movement, where they extend and retract their shape, or by using structures like cilia and flagella for propulsion. The movement of cells is often guided by chemical signals in their environment, a process known as chemotaxis. Cells can detect these signals and respond by moving toward or away from them. This ability to navigate is crucial for processes like embryonic development and the body's defense against infections.
