Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
Do somatic cells produce gametes?
The two sequential division processes of meiosis culminate in the production of gametes with only half the number of chromosomes of somatic cells. As a result, human sperm and ova each have only 23 single-stranded chromosomes.
What are somatic cells and gamete cells?
Somatic cells are any cell in the body that are not gametes (sperm or egg), germ cells (cells that go on to become gametes), or stem cells. Essentially, all cells that make up an organism’s body and are not used to directly form a new organism during reproduction are somatic cells.
What is an example of a somatic cell?
Somatic cells are all cells of the body apart from gamete (sperm cells and egg cells). As such, they include cells that make up different parts of the body including liver cells, skin cells, and bone cells among others.
Is a liver cell somatic or gamete?

What are two types of somatic cells?
In plants and animals, there are two major categories of cells: somatic cells and reproductive cells, known as germ cells or gametes. In humans and other animals, they are the egg and sperm cells. All other cells in the body are somatic cells. Think of every body part you have; they are all made of somatic cells.
How many somatic cells are there?
What do somatic cells contain?
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent. Mutations in somatic cells can affect the individual, but they are not passed on to offspring.
What does somatic mean?
1 : of, relating to, or affecting the body especially as distinguished from the germplasm. 2 : of or relating to the wall of the body : parietal.
Do all somatic cells have the same DNA?
All body cells have the same DNA. However, the difference between cells in different tissues and organs is that the expression of the genes differs between cells. Mitosis (somatic cell division) produces two daughter cells that have the same genetic component as the parent cell.
Is skin a somatic cell?
Every other cell type in the mammalian body, apart from the sperm and ova, the cells from which they are made (gametocytes) and undifferentiated stem cells, is a somatic cell; internal organs skin, bones, blood and connective tissue are all made up of somatic cells. …
What is the difference between somatic cells and germ cells?
Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. … Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis. The lineage of germ cells is called germ line.
Do all somatic cells have 46 chromosomes?
All somatic (body) cells (gametes [sperm and egg] are not called somatic cells) have 46 chromosomes (40 in the mouse), half of which came from the father and half from the mother.
Is a liver cell somatic?
The somatic cells that have differentiated can become adult neurons in the nervous system, blood cells in the cardiovascular system, liver cells in the digestive system, or any of the many other types of cells found throughout the body. …
What are the three phases of the somatic cell cycle?
One “turn” or cycle of the cell cycle consists of three general phases: interphase, mitosis, and cytokinesis.
What is the difference between somatic and reproductive cells?
Organisms that reproduce sexually produce sex cells, or gametes, that carry a single set of chromosomes, the haploid number for the species. In contrast, body, or somatic, cells are the regular cells that form the organism’s tissues and organs.
