To put it simply, it is the cell membrane. You can have transport vesicles ect, but the cell membrane is the main barrier between inside and outside. It contains pumps, channels and proteins that are in charge of communication and also control movement of everything from inside and outside.

The cell membrane controls what enters and leaves the cell. There are protein channels within the lipid bilayer (membrane) of the cell. There are carbohydrate chains that hang off of the protein channels that identify each particle around the cell to make sure its what the cell needs, if not it wont let it in.
Cell membrane controls the passage of molecules in and out of the cell through selective permeability. This allows specific molecules to pass through while preventing others from entering or exiting the cell. The cell membrane contains protein channels and pumps that regulate the movement of ions and molecules.
Cell membrane
The nucleus, specifically through its regulation of gene expression, controls the production of proteins that are involved in cell movement. Additionally, the cytoskeleton plays a key role in cell movement by providing structural support and facilitating movement of organelles.
The cell membrane, also known as the plasma membrane, is responsible for regulating the flow of nutrients in and out of the cell. It controls the movement of molecules by facilitating selective permeability.

The cell membrane, made up of phospholipids and proteins, controls the passage of substances into and out of animal cells. Selective permeability allows for the regulation of what molecules can enter and leave the cell, maintaining internal conditions necessary for proper cell function. Transport proteins, such as channels and carriers, play a key role in facilitating the movement of specific molecules across the cell membrane.
The cell membrane.
The cell membrane controls entry into and out of the cell. It is selectively permeable, allowing some substances to pass through while blocking others. Transport proteins and channels in the membrane facilitate the movement of specific molecules in and out of the cell.
Cell membrane
The cell membrane regulates the movement of materials in and out of the cell through processes such as diffusion, osmosis, and active transport. Additionally, specific transport proteins embedded in the membrane facilitate the passage of certain molecules and ions.

The cell membrane, also known as the plasma membrane, is responsible for regulating the flow of nutrients in and out of the cell. It controls the movement of molecules by facilitating selective permeability.
The plasma membrane controls the passage of nutrients into the cell and wastes out of the cell through a process called selective permeability. This involves transport proteins and channels that regulate the movement of molecules based on size, charge, and concentration gradients.
