The cell takes in food and water and eliminates wastes through the cell membrane.

Here's why:

* Cell membrane: This is a thin, flexible barrier that surrounds the cell. It controls what enters and leaves the cell, acting like a gatekeeper.

* Food and water: The cell membrane allows small molecules of food and water to pass through into the cell.

* Wastes: Waste products from the cell's activities are transported out through the cell membrane.
