What types of things pass through a cell membranes

Water, H20, Etc.

Explanation:

Small and simple molecules like water, H2O, can pass through the cell membrane easily as it is partially permeable. The cell membrane can filter out unimportant molecules that the cell does not need to use, and also only lets small molecules pass through.

oxygen and carbon dioxide, and hydrophobic molecules such as lipids, pass through the cell membrane.
