Cell contents are separated from the external environment by the cell membrane. Cells are also separated by the external environment when they are in the bloodstream in the capillaries and veins.
It's enclosed by a barrier known as plasma membrain.

the cell is covered in membrane and it surrounds the cell to protect anything like bacteria from getting in and out of the cell.
The nucleus as a whole is not separated from the cytoplasm, which surrounds it. However, the contents of the nucleus (DNA and assorted proteins) is separated from the cytoplasm by the nuclear membrane (a.k.a the nuclear envelope), which is the outer portion of the nucleus.

The barrier between the inside of a cell and its enviorment is a CELL MEMBRANE
It is a cell wall that surrounds the cell outside its cell membrane
