    Carmella is right, the cell membrane controls what enters and leaves the cell. Technically, the cell membrane is not an organelle, though.

    Control of what passes into and out of the cell is an active, not a passive process, and often depends on the types of proteins embedded in or attached to the lipid bilayer of the membrane. In this respect, it is under the control of the cell's DNA, because the proteins which end up in the cell membrane are built according to instructions in the DNA.
