Multiple Choice

What is the primary difference between rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER)?

RER is found only in animal cells, while SER is found only in plant cells.

RER is responsible for detoxification, while SER is responsible for energy production.

RER is involved in lipid synthesis, while SER is involved in protein synthesis.

RER has ribosomes on its surface, while SER does not.

Verified step by step guidance

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

Identify the two types of endoplasmic reticulum: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).

Recognize that the rough endoplasmic reticulum (RER) is characterized by the presence of ribosomes on its surface, which gives it a 'rough' appearance under a microscope. These ribosomes are essential for protein synthesis.

Understand that the smooth endoplasmic reticulum (SER) lacks ribosomes on its surface, giving it a 'smooth' appearance. The SER is primarily involved in lipid synthesis and detoxification processes.

Conclude that the primary difference between RER and SER is the presence of ribosomes on the RER, which are absent on the SER, leading to their distinct roles in the cell.
