The structure that limits the movement of particles into and out of the cell is the cell membrane, also known as the plasma membrane. This selectively permeable barrier is composed of a lipid bilayer with embedded proteins, which regulate the passage of substances. It allows essential molecules to enter while keeping harmful substances out, maintaining the cell's internal environment.

What cell structure that allows cummunication between internal and external cell environment?

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.


Supporting structure of the cell that is also involved in movement is called what?

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.


What is A cell moving particles with the use of energy is called?

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


What is the structure that surrounds every cell?

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.

What unique cell structure does amoeba have?

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.
