Answer:
<u>Peroxisome</u> is not the part of endomembrane system
(<u>Mitochondria</u> and <u>Chloroplasts</u> are also not included in the endomembrane system)
Explanation:.
The endomembrane system is composed of the different membranes which are suspended in the cytoplasm within a eukaryotic cell. They include :
1) Nuclear membrane
2) Endoplasmic reticulum
3)Golgi apparatus
4) Lysosomes
5) Vesicles
6) Endosomes
These membranes divide the cell into functional and structural components.
<u>Peroxisomes</u> are also covered with membranes but they are not considered as the part of endomembrane system as <u>they don't recieve vesicles from Golgi apparatus.</u>
Similarly the membranes of mitochondira and the chloroplasts also are not included in the endomembrane system because their functions are not coordinated with the organelles involved in the endomembrane system.
