Final answer:
The Golgi apparatus relies on exocytosis to transport modified proteins and lipids out of the cell. It modifies, sorts, and packages molecules received from the rough ER for secretion
Step-by-step explanation:
The correct option is A:
The organelle that relies on exocytosis to complete its function is the Golgi apparatus.
Exocytosis is a cellular process where substances are transported out of the cell via vesicles. The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum (ER). It then modifies, sorts, and packages these molecules for transport to other locations inside or outside of the cell. When the Golgi apparatus sends these molecules out of the cell, it uses exocytosis.
This process allows cells to secrete substances such as enzymes, hormones, and antibodies. Therefore, the Golgi apparatus plays a critical role in managing cellular exports through this mechanism, illustrating the complex and interconnected systems within eukaryotic cells that allow them to function properly.
