The cell membrane is reposnible for allowing what substances can enter and leave a cell, this happens by different methods of transport for instance "active transport" in plants.
The phospholipid bilayer containing cholesterol, proteins and carbohydrates, also helps in allowing which substances to pass.
the cell membrane controls what goes in and out of the cell

The answer is nucleus :)
The Cell surface membrane controls what enters and leaves the cell
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
The cell Membrane allows substances to go in and out
The be more specific if is a part off the cell that controls the cell.it is surronding parts in the cell
it is the cell wall ! :)
The cell membrane. It is described as semipermeable
Cell membrane
The cell wall in plants and the cell membrane in animals and bacteria.
Ask a college professor, not me.
The answer is nucleus :)
The Nucleus
I think you are talking about the nucleus, which is the "brain" of the cell. It controls everything that cell does.
The nucleus is the part of the cell that controls all the activities of the cell. The nucleus is like the main office of a factory.
The nucleus is what controls the cell.
