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.
hhh
The cell membrane controls the movement of materials that enter and exit the cell.

The Cell membrane
The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells.
decreased movement of molecules entering the cells decreased movement of molecules entering the cells

This would be the nucleus which is like the brain of the cell. it controls it - the nucleus isn't a cell, its part of a cell :)

The cell membrane controls the movement of materials in and out of the nucleus. This helps to support and homeostasis.
