How does the cell membrane of a tube worm maintains a stable environment

The cell membrane of a tubeworm is selectively permeable and they prevent minerals in the water from flowing it in the cell of tube worms. By doing this the cell membrane protects the cell from any osmotic damage. By selectively preventing these minerals it maintains the stable environment in the cell

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
