Water enters a cell and waste material leaves a cell through the cell membrane. Based on this information, the cell membrane is semi-permeable transparent. rigid. impermeable.

The correct answer is: semi-permeable.<br /><br /> membrane is semi-permeable, meaning it allows certain substances to pass through while preventing others from entering or leaving the cell. This selective permeability is crucial for maintaining the proper balance of substances inside the cell, such as water, ions, and nutrients. The cell membrane controls the movement of substances in and out of the cell through various mechanisms, including diffusion, osmosis, and active transport.
