The somatic cell cycles discussed so far in this chapter result in diploid daughter cells with identical genetic complements. … Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Do all somatic cells undergo mitosis?
All somatic cells undergo mitosis, whereas only germ cells undergo meiosis. Meiosis is very important because it produces gametes (sperm and eggs) that are required for sexual reproduction.
Why do somatic cells need to undergo mitosis?
Mitosis is crucial to this process. Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.
Do somatic cells divide?
Somatic cells divide regularly; all human cells (except for the cells that produce eggs and sperm) are somatic cells. Somatic cells contain two copies of each of their chromosomes (one copy from each parent). The cell cycle has two major phases: interphase and the mitotic phase.
When somatic cells undergo mitosis what is the result?
Cells that undergo mitosis duplicate their chromosomes, resulting in cells with two times their normal haploid or diploid numbers (4N chromosomes). Newly-synthesized chromosomes remain closely associated with their like-chromosome. These two identical chromosomes are called sister chromatids.
What cells undergo mitosis in humans?
Three types of cells in the body undergo mitosis. They are somatic cells, adult stem cells, and the cells in the embryo. Somatic cells – Somatic cells are the regular cells in the body of multicellular organisms. Some examples of somatic cells are epithelial cells, muscle cells, liver cells, etc.
What are examples of somatic cells?
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. Mature somatic cells are highly specialized and therefore perform very specific functions.
What is the function of somatic cell division?
“Somatic cells” is a fairly general term which refers to essentially all the cells of the body except for the germ line; the germ line being the cells in the sexual organs that produce sperm and eggs. So anything that doesn’t have the job of producing sperm or eggs is a somatic cell.
Do nerve cells undergo mitosis?
Unlike other body cells, neurons don’t undergo mitosis (cell splitting). Instead, neural stem cells can generate new specialized neurons by differentiating into neuroblasts that, upon migration to a specific area, can turn into a neuron.
What is the somatic cell division?
Somatic cell division is the type of cell division where the daughter cells produced are exactly similar to the parent cell. They have the same chromosomal number as the parent cell. Mitosis occurs in all the somatic cells of the body.
What are two types of somatic cells?
Somatic cells are the cells of an organism that are not germ cells, or reproductive cells. Somatic cells are highly specialized and can be very different from one another. Some examples of somatic cells include nerve cells, skin cells, and blood cells.
How many somatic cells do humans have?
In the human body, there are about 220 types of somatic cells.
How do somatic cells reproduce?
Somatic cells are a regular type of body cell that is not involved in any way in sexual reproduction. In humans, such cells are diploid and reproduce using the process of mitosis to create identical diploid copies of themselves when they split.
Does mitosis occur in humans?
There are two ways cell division can happen in humans and most other animals, called mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes.
Do egg cells undergo mitosis?
Eggs are haploid cells, having half the number of chromosomes of other cells in the body, which are diploid cells. … Oogenesis begins when an oogonium (with the diploid number of chromosomes) undergoes mitosis to form primary oocytes (also with the diploid number of chromosomes).
Can triploid cells undergo mitosis?
Edit: Of course a triploid cell CAN undergo mitosis. (daughter cells with 3 chromosomes each).
