Which one of the following statements is false? The endomembrane system?

a. includes the rough and smooth endoplasmic reticulum.


b. is involved in the synthesis, storage, and export of important molecules.


c. includes the nuclear envelope.


d. divides the cell into compartments.


e. is a system of interrelated membranes that are all physically connected.Which one of the following statements is false? The endomembrane system?
I believe that (e) is false.


The endomembrane system includes the endoplasmic reticulum(a), which also synthesizes and transports(b). It also includes the nuclear envelope(c), but not the nucleus itself. It also divides the cell into compartments(d), but all the membranes and organelles do not connect(e).Which one of the following statements is false? The endomembrane system?
Based on the question, E is the most likely choice. I say that because the endomembrane system divides the cell into internal compartments and organelles but they are not necessarily all physically connected. For example, the Golgi Apparatus has a membrane but it is not physically connected to other membranous organelles. Thus, each of those choices is true, except E.
