Question

The rough endoplasmic reticulum owes its rough surface to

• A. mitochondria
• B. proteins
• C. ribosomes
• D. DNA particles

Answer 1

The correct option is C

ribosomes

The correct option is C

Explanation of the correct option:

1. The endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus.
2. The endoplasmic reticulum (ER) helps in the synthesis of protein and phospholipids.
3. ER is of two types, Rough endoplasmic reticulum, and Smooth endoplasmic reticulum.
4. The rough endoplasmic reticulum synthesizes protein as it has ribosomes on its surface, and the smooth endoplasmic reticulum synthesizes phospholipids.

Explanation of the incorrect option:

Option A:

1. Mitochondria are the cell organelles that generate electricity or power for the cell to perform functions.
2. Power is in the form of energy.

Option B:

1. Proteins are polymers of amino acids.
2. Proteins are formed by ribosomes present on RER.

Option D:

1. DNA is a genetic material that stores information and transfer it to next generation.

Final answer: The rough endoplasmic reticulum owes its rough surface to ribosomes.
