Germ-line cells undergo meiosis to produce haploid gametes which have only one copy of each chromosome. These haploid gametes fuse to form a diploid embryo that grows into the adult. Meiosis is just one step in the life cycle of a germ-line cell.Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. These cells are sometimes said to be immortal because they are the link between generations. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis.Germ cells undergo meiosis, e.g. primary spermatocytes and primary oocytes in males and females, respectively and in pollen mother cells and megaspore mother cells in angiosperms.

Is germ cells mitosis or meiosis?
Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. These cells are sometimes said to be immortal because they are the link between generations. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis.
What type of cells undergo meiosis?
Germ cells undergo meiosis, e.g. primary spermatocytes and primary oocytes in males and females, respectively and in pollen mother cells and megaspore mother cells in angiosperms.

Does mitosis occur in germline cells?
Yes, germ cells go through mitosis to increase the number of diploid cells before entering gametogenesis to produce gametes associated with the…
Are germline cells haploid or diploid?
Germ line cells are haploid, which means they contain a single set of chromosomes. In diploid cells, one set of chromosomes is inherited from the individual’s mother, while the second is inherited from the father. Humans have 46 chromosomes in each diploid cell.
Which types of germ cells does not undergo cell division?
While there are a few cells in the body that do not undergo cell division, most somatic cells divide regularly. A somatic cell is a general term for a body cell: all human cells, except for the cells that produce eggs and sperm (which are referred to as germ cells), are somatic cells.
Do all cells go through meiosis?
Meiosis does not occur in all cells.
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization.
Why do meiosis and mitosis occur in germ cells?
Yes. Meiosis occurs in germ cells. Both mitosis and meiosis occur in germ cells as they are required to develop and grow the complicated organ structures of its parents which necessitates cell division. Hence, mitosis and meiosis ensures cell division and organization occurs in germ cells.

Meiosis and Fertilization – The Cell – NCBI Bookshelf
Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Germ cell – Wikipedia
In many animals, the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonads. There, they undergo meiosis, …
Germ Cell – an overview | ScienceDirect Topics
This route utilizes meiosis and gametogenesis, processes that are unique to germ cells. Germ cells differentiate to produce male and female gametes, sperm and …
Meiosis in Humans | The Embryo Project Encyclopedia
Meiosis occurs in the primordial germ cells, cells specified for sexual reproduction and separate from the body’s normal somatic cells. In …
Which types of cells undergo mitosis?
Mitosis happens in all eukaryotic cells (plants, animals, and fungi). It is the process of cell renewal and growth in a plant, animal or fungus. It is continuously occurring throughout our bodies; it is even happening while you are reading this.
Does meiosis occur in somatic cells?
Answer and Explanation: Meiosis can only occur in germline cells, which produce gametes, like eggs and sperm. Somatic cells divide through mitosis where the daughter cells…

Why do germ cells undergo mitosis?
Unlike somatic cells which build the multicellular body of the organism through mitotic division, germ cells undergo cell division to produce gametes which are haploid and involved in sexual reproduction.
What is germline cells?
Germ Line
Germ line refers to the sex cells (eggs and sperm) that sexually reproducing organisms use to pass on their genomes from one generation to the next (parents to offspring). Egg and sperm cells are called germ cells, in contrast to the other cells of the body, which are called somatic cells.
How do human germ cells divide?
Two types of cell division occur in germline cells: Mitosis involves one round of cell division and makes an exact copy of a cell. Meiosis involves two rounds of cell division and produces cells with half the number of chromosomes as the original cell.
Why are germ cells haploid?
Each mature germ cell is haploid, meaning that it has a single set of 23 chromosomes containing half the usual amount of DNA and half the usual number of genes. Except for the egg and the sperm, most cells in the human body contain the entire human genome. Also known as a gamete.
Is diploid mitosis or meiosis?
…
Mitosis vs. Meiosis.
| Mitosis | Meiosis |
|---|---|
| Produces diploid cells | Produces haploid cells |
| Daughter cells are genetically identical | Daughter cells are non-identical |
Why does meiosis occur only in germ cells?
Answer: Meiosis and mitosis occur in germ cells. This is because, the germ cells need to grow and develop the complex organ system of its parents, for which cell division is absolutely important.
Which cells Cannot undergo mitosis?
Skin cells, red blood cells or gut lining cells cannot undergo mitosis. Stem cells do divide by mitosis and this makes them very important for replacing lost or damaged specialized cells. What is a stem cell? Stem cells are different from other cells of the body because stem cells can both: 1.

What cells do not undergo mitosis?
What types of cells do not undergo mitosis? Sperm cells and egg cells don’t go through mitosis. Describe how mitosis is important for your body. Mitosis is just one small part of the cell cycle!
How is meiosis different from mitosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
