Which cell organelle acts as the traffic police of the cell?

The Golgi body, also known as the Golgi apparatus, functions as the cell's "traffic police" by sorting, modifying, and packaging proteins and lipids for transport to their appropriate destinations within or outside the cell.

This organelle ensures that molecules synthesized in the endoplasmic reticulum are correctly processed and directed, maintaining efficient cellular operations.

In contrast, the other options have different primary functions:

• Endoplasmic reticulum: Synthesizes proteins and lipids.
• Lysosomes: Break down waste materials and cellular debris.
• Ribosomes: Synthesize proteins.

Therefore, the Golgi body is aptly termed the "traffic police" of the cell due to its crucial role in managing intracellular transport.
