Cytoskeleton is the supporting structure of a cell that is also involved in movement. It consists of protein filaments such as actin, microtubules, and intermediate filaments that provide structural support and help in cell movement.
The movement of large particles of solid food or whole cells into the cell is called phagocytosis. Phagocytosis occurs in three separate steps.
Cilia and Flagella.
Amoebas have an unusual cell structure called pseudopods, which are temporary projections of the cell membrane that enable the amoeba to move, feed, and engulf bacteria and other particles. This structure allows amoebas to change shape and move in a process called amoeboid movement.

The cell membrane is the structure that allows communication between the internal and external cell environment. It controls the movement of molecules in and out of the cell, helping to maintain homeostasis and respond to changes in the cell's surroundings.
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
cell membrane
The thin structure that surrounds the cytoplasm of a cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
The movement of large particles of solid food or whole cells into the cell is called phagocytosis. Phagocytosis occurs in three separate steps.
