Question

Which human cell does not contain mitochondria?
a. Nerve cell
b. Red blood cell
c. White blood cell
d. Liver cell

Answer 1

Hint: Cells are mainly considered as the building blocks of the living things and the human body is mainly composed of trillions of cells. Generally, the cells provide the main structure to the body and have cell organelles in them. Some cells lack few cell organelles.

Complete answer:
The correct answer to this question is the second option that is the option (b) red blood cell. As the only cell which does not contain or have the mitochondria is the red blood cell. Red blood cell does not contain organelles like nucleus and mitochondria. Hence the red blood cell does not use any of the oxygen they transport. Instead, they produce energy in the form of ATP with the help of glycolysis of glucose and lactic acid fermentation.
The first option is the nerve cell which does contain the mitochondria; hence it is the wrong answer.
The second option is the red blood cell which is the correct answer to this question. The third option is the white blood cell which also contains mitochondria; hence it is also the wrong answer. The fourth option is the liver cell which also has mitochondria hence it is also the wrong answer.

Additional Information:
Red blood cells are also known as the haematodes and red blood cell corpuscles. These are the most common type of blood cell, which has the main function of delivering oxygen to the body tissues.
The red blood cell takes and carries oxygen from the lungs in humans and then releases in the body tissues with the help of blood capillaries.

Note: Red blood cells are mainly the round structure with the flattish center in the middle. The main work and function of the red blood cell are to carry oxygen with the help of the protein present in them, which is known as Haemoglobin. This is not only the one function but it also helps in the removal of carbon dioxide from the body. These cells are generally made in the bone marrow. Their life span is about 120 days, after that, they die.
