Read the following statements regarding the endomembrane system: (A) The endomembrane system includes all membrane-bound organelles of a eukaryotic cell. (B) The functions of endoplasmic reticulum, Golgi complex, lysosomes, and vacuoles are coordinated. (C) Ribosomes are an integral part of the endomembrane system as they are attached to the rough endoplasmic reticulum. (D) Peroxisomes are excluded from the endomembr

Step-by-step solution

Statement (A) is incorrect because the endomembrane system does not include all membrane-bound organelles; mitochondria, chloroplasts, and peroxisomes are excluded as their functions are not coordinated with the others. Statement (B) is correct as the coordination of functions is the defining criterion for the endomembrane system. Statement (C) is incorrect because ribosomes are non-membrane bound organelles and are not considered part of the endomembrane system, despite their physical association with the rough en
