Do liver cells contain the same chromosomes as cheek cells?


In this article, we will explore the question of whether liver cells and cheek cells contain the same chromosomes. We will delve into the structure and function of both liver cells and cheek cells, compare their characteristics, and examine the chromosomes present in each type of cell. By the end, we will have a clear understanding of whether the two cell types share the same chromosomes.

The Structure and Function of Liver Cells

Liver cells, also known as hepatocytes, are the main functional cells of the liver. The liver is a vital organ responsible for various metabolic processes in the body, including detoxification, protein synthesis, and bile production. Liver cells have a unique structure that allows them to perform these functions efficiently.

Hepatocyte Structure

Hepatocytes have a polygonal shape and are arranged in rows called hepatic plates. These plates are surrounded by blood vessels, allowing efficient exchange of nutrients and waste products. The cytoplasm of hepatocytes is rich in various organelles, including mitochondria, endoplasmic reticulum, and Golgi apparatus.

Hepatocyte Function

Hepatocytes perform several important functions in the body, including:

  1. Detoxification: Liver cells help detoxify harmful substances such as drugs, alcohol, and toxins by metabolizing them into less harmful compounds.
  2. Protein Synthesis: Hepatocytes are responsible for the synthesis of various proteins, including albumin, which is essential for maintaining osmotic pressure in the blood.
  3. Bile Production: Liver cells produce bile, a substance necessary for the digestion and absorption of fats.
  4. Glycogen Storage: Hepatocytes store glycogen, a polysaccharide that serves as a readily available energy source.

The Structure and Function of Cheek Cells

Cheek cells, also known as buccal cells, are the cells that line the inner surface of the cheeks. They are simple squamous epithelial cells that play a role in protecting the underlying tissues and assisting in various physiological processes.

Cheek Cell Structure

Cheek cells have a flat, irregular shape and are tightly packed together to form a protective barrier. They lack specialized organelles, such as mitochondria and Golgi apparatus, but contain a nucleus and other basic cell structures.

Cheek Cell Function

Cheek cells serve several functions in the body, including:

  1. Protection: Cheek cells form a physical barrier that helps protect the underlying tissues from injury and infection.
  2. Taste Sensation: The taste buds located on the surface of cheek cells play a role in taste sensation.
  3. Cellular Adhesion: Cheek cells adhere to each other, maintaining the structural integrity of the oral cavity.

Chromosomes in Liver Cells

Chromosomes are structures within cells that contain genetic material in the form of DNA. They are responsible for carrying the hereditary information necessary for the development and functioning of an organism. Each species has a specific number of chromosomes, and liver cells in humans typically contain 46 chromosomes.

Human Chromosomes

Human chromosomes exist in pairs, with each pair consisting of one chromosome inherited from the mother and one from the father. Of the 46 chromosomes in a human liver cell, 22 pairs are autosomes, and one pair is the sex chromosomes (XX in females and XY in males).

Chromosomes in Cheek Cells

Like liver cells, cheek cells also contain chromosomes. However, cheek cells are somatic cells, which means they are non-reproductive cells and do not contribute to the formation of gametes (sperm or eggs). Therefore, cheek cells also contain 46 chromosomes, arranged in the same pairs as liver cells.


In conclusion, both liver cells and cheek cells contain the same number of chromosomes, which is 46 in humans. Liver cells, being the functional cells of the liver, have specific structures and functions related to their role in metabolism and detoxification. Cheek cells, on the other hand, serve a protective function in the oral cavity. Despite their different functions, both cell types share the same chromosomal arrangement, with 22 pairs of autosomes and one pair of sex chromosomes. This demonstrates the consistency of the genetic information across various cell types in the human body.
