For which of the following organelles are the structure and function correctly described?
A)Endoplasmic reticulum-a network of interconnected membranes forming sacs and canals that packages protein molecules for secretion
B)Ribosomes-membranous vesicles containing digestive enzymes
C)Golgi apparatus-particles, composed of protein and RNA, which synthesize proteins
D)Mitochondrion-nonmembranous structure that synthesizes proteins

Question

Quizplus · Accepted Answer

The structure and function described for the endoplasmic reticulum are correct. The endoplasmic reticulum is a network of interconnected membranes forming sacs and canals that package protein molecules for secretion.

Answer: B, C, D are incorrect.
 The structure and function described for ribosomes, Golgi apparatus, and mitochondrion are incorrect. Ribosomes are not membranous vesicles containing digestive enzymes but rather small structures that synthesize proteins. The Golgi apparatus does not synthesize proteins but rather modifies, sorts, and packages them. Mitochondria are membrane-bound structures that synthesize ATP, not proteins, and are not nonmembranous.
