Question: 146 Which of the following are NOT considered as the part of endomembrane system?
A. Mitochondria
B. Endoplasmic Reticulum
C. Chloroplasts
D. Golgi complex
E. Peroxisomes
Choose the most appropriate answer from the options given below:
(1) A and D only
(2) A, D and E only
(3) B and D only
(4) A, C and E only
Answer: Option (4)
Explanation:
The endomembrane system includes cell organelles that are functionally connected through vesicular transport.
The main components of the endomembrane system are endoplasmic reticulum, Golgi complex, lysosomes and vesicles.
Mitochondria are not part of the endomembrane system because they have their own double membrane and function independently in cellular respiration.
Chloroplasts are also not included as they are semi-autonomous organelles involved in photosynthesis and possess their own genetic material.
Peroxisomes are not part of the endomembrane system because they are not derived from the endoplasmic reticulum or Golgi apparatus and function independently in oxidative reactions.
Therefore, mitochondria, chloroplasts and peroxisomes are NOT
considered part of the endomembrane system.
