Which of the Following Structures Make the Rough Endoplasmic Reticulum

Question

Which of the following structures make the rough endoplasmic reticulum look like sandpaper?
A) Ribosomes
B) Globs of cytoplasm
C) ATP
D) Fragments of DNA

Accepted Answer

Ribosomes are the structures that make the rough endoplasmic reticulum look like sandpaper. Ribosomes are small organelles that attach to the surface of the endoplasmic reticulum, giving it a rough texture that looks like sandpaper. This rough ER is involved in the synthesis and packaging of proteins for export or use within the cell.
