Question

Quizplus · Accepted Answer

The plasma membrane of a cell serves as a barrier, allowing certain substances to enter and exit while keeping out others. The screen door works in a similar way, allowing air and smells to pass through while keeping insects out. The cytosol and ER lumen are not analogous to a screen door, and a ribosome is involved in protein synthesis, which is not relevant to the function of a screen door.
