Cell Structure and Compartments

Q1: Which of the following two organelles look most alike structurally?

A Nucleus and vesicle

B Golgi apparatus and smooth endoplasmic reticulum ER

C Vacuole and cytoskeleton

D Lysosome and chloroplast

ANS:B - Golgi apparatus and smooth endoplasmic reticulum ER

Both look structurally the same as they both are composed of flattened cisternae. The difference is that sER is involved in lipid and steroid metabolism while the function of the Golgi is for chemical modification of proteins, sorting and packaging of molecules for secretion or transport to the other organelles.
