Which organelle packages proteins and directs them to their destinations inside the cell?

Explanation:
Proteins that are made in the cell are processed, packaged, and sent to their destinations by a shipping center inside the cell. The Golgi apparatus acts as that center. It receives proteins from the endoplasmic reticulum, modifies them (think adding sugar tags and other small changes), and then packages them into vesicles. These vesicles carry the proteins to where they’re needed—like the cell membrane, lysosomes, or outside the cell—by following cellular “addresses” that direct traffic. The other organelles don’t perform this routing role: the nucleus stores genetic material, ribosomes build proteins but don’t direct their final destination, and lysosomes break down waste rather than sort and dispatch proteins.
