Answer 1

The cell membrane can be compared to a security guard who decides who can enter a building.

Step-by-step explanation:

The organelle that can be compared to a security guard who decides whom may enter a building or not is the cell membrane. The cell membrane is a thin, flexible barrier that surrounds the cell and regulates the movement of substances in and out of the cell, similar to how a security guard decides who can enter a building. It allows certain molecules to enter or exit the cell while blocking others, just like a security guard controlling access to a building.
