Question : Endoplasmic Reticulum is rough because of _____ present on their surface.
Option 1: Golgi bodies
Option 2: Plastids
Option 3: Lysosomes
Option 4: Ribosomes
Correct Answer: Ribosomes
Solution : The correct option is Ribosomes.
When the cytoplasmic surface of the endoplasmic reticulum (ER) is covered with Ribosomes, it is referred to as "rough". When seen under a microscope, these ribosomes give the rough endoplasmic reticulum its distinctive look. The presence of ribosomes on the rough ER suggests that this region of the ER is engaged in protein synthesis.
