Question

Which of the following differentiates the rough endoplasmic reticulum from the smooth endoplasmic reticulum?

• A. Lysosomes
• B. Ribososmes
• C. Mitochondria
• D. Golgi apparatus
• E. Histones

Answer 1

The correct option is B Ribososmes

• The endoplasmic reticulum is a complex yet well-organized organelle of the eukaryotic cell.
• It plays a major role in the manufacturing and packaging of proteins.
• ER is of 2 types:

1. Rough endoplasmic reticulum - It consists of ribosomes on its external surface, thus giving it a rough appearance and is responsible for protein synthesis.
2. Smooth endoplasmic reticulum - It doesn't have ribosomes and is smooth in appearance, its main function is to produce cellular products like hormones and lipids.

Hence, the correct answer is option B.
