Here's why:
* Packaging and Processing: The Golgi apparatus acts like a cellular post office. It receives proteins and lipids (fats) from the endoplasmic reticulum (ER), modifies them, packages them into vesicles (tiny sacs), and then sends them to their final destinations within the cell or outside the cell.
* Vesicle Transport: These vesicles, which are like tiny bubbles, carry the packaged substances to different parts of the cell, such as the cell membrane, lysosomes, or other organelles.
