The Endoplasmic Reticulum is an Example of A(n) ________ Organelle

Question

The endoplasmic reticulum is an example of a(n) ________ organelle.
A) filamentous
B) extracellular
C) interstitial
D) membranous
E) bound

Accepted Answer

The endoplasmic reticulum is a membranous organelle, meaning it is surrounded by a membrane. This is in contrast to filamentous or interstitial structures that lack a membrane, and extracellular structures that are not contained within the cell. The term "bound" is not typically used to describe organelles.
