Final answer:
The cell membrane is the feature of a cell that allows water molecules to pass into the cell while larger molecules cannot.
Step-by-step explanation:
The feature of a cell that allows water molecules to pass into the cell while larger molecules cannot is the cell membrane. The cell membrane is a selectively permeable barrier that regulates the movement of substances in and out of the cell. It is composed of a phospholipid bilayer embedded with proteins. Small, non-charged molecules like water can pass through the cell membrane freely through a process called osmosis, while larger molecules are prevented from entering the cell.
