* Cell Membrane (Plasma Membrane):
* Surrounds the entire cell.
* Acts as a barrier between the cell's internal environment (cytoplasm) and the external environment.
* Controls what enters and leaves the cell (selective permeability).
* Composed of a phospholipid bilayer with embedded proteins.
* Nuclear Membrane (Nuclear Envelope):
* Surrounds the nucleus of the cell.
* Acts as a barrier between the nucleus and the cytoplasm.
* Contains pores that allow certain molecules to pass through.
* Is a double membrane structure, with each membrane being a phospholipid bilayer.
In summary:
* Both are membranes made of phospholipids, but they have different locations and functions.
* The cell membrane is the outer boundary of the cell, while the nuclear membrane encloses the nucleus.
