The answer is: mitochondrion.

Explanation for each option:

  1. Rough endoplasmic reticulum (RER): The RER is part of the endomembrane system. It is involved in the synthesis of proteins that are either secreted from the cell, incorporated into the cell's plasma membrane, or sent to an organelle.

  2. Smooth endoplasmic reticulum (SER): The SER is also part of the endomembrane system. It is involved in lipid synthesis, detoxification processes, and calcium ion storage.

  3. Mitochondrion: The mitochondrion is NOT part of the endomembrane system. It is primarily involved in energy production through the process of oxidative phosphorylation and has its own distinct set of membranes and functions.

  4. Golgi apparatus: The Golgi apparatus is part of the endomembrane system. It modifies, sorts, and packages proteins and lipids for secretion or for use within the cell.

Summary: The mitochondrion is the organelle that is not part of the endomembrane system, while the rough endoplasmic reticulum, smooth endoplasmic reticulum, and Golgi apparatus are all components of this system.
