The organelle that relies on exocytosis to complete its function is the Golgi apparatus.
Explanation
- The Golgi apparatus processes and sorts proteins and lipids synthesized in the endoplasmic reticulum and packages them into vesicles that are transported to the plasma membrane.
- These vesicles then undergo exocytosis, fusing with the plasma membrane to release their contents outside the cell or to deliver membrane proteins and lipids to the plasma membrane.
- This exocytosis step is essential for the Golgi apparatus to fulfill its role in secretion and membrane component delivery, making it reliant on this process for its function.
Other organelles mentioned, such as vacuoles, mitochondria, and endoplasmic reticulum, do not primarily depend on exocytosis to complete their key functions.
