Verified step by step guidance

Begin by understanding the structure and function of the endoplasmic reticulum (ER). The ER is a network of membranes within the cell that plays a crucial role in the synthesis and transport of proteins and lipids.

Differentiate between the two types of ER: rough ER and smooth ER. The rough ER is characterized by the presence of ribosomes on its surface, giving it a 'rough' appearance under a microscope.

Recognize the role of ribosomes. Ribosomes are the cellular structures responsible for protein synthesis. They translate messenger RNA (mRNA) into polypeptide chains, which are then folded into functional proteins.

Understand why ribosomes are associated with the rough ER. The rough ER is involved in the synthesis of proteins that are either secreted from the cell, incorporated into the cell's plasma membrane, or sent to an organelle. The ribosomes on the rough ER facilitate this process.

Conclude that the presence of ribosomes is what distinguishes the rough ER from the smooth ER, which lacks ribosomes and is involved in lipid synthesis and detoxification processes.
