a cell - membrane
b cell - wall
c nucleus
d ribosome

Explanation:

Water passes into and out of cells through the cell membrane, which is semi - permeable and regulates the movement of substances including water to maintain a steady state of water amount in the cell. The cell wall provides structural support, the nucleus contains genetic material, and ribosomes are involved in protein synthesis, none of which are the main structure for water passage.
