Which division takes place in germ cell?
Meiosis I is a unique cell division that occurs only in germ cells; meiosis II is similar to a mitotic division.
Does mitosis occur in germ cells?
Germ cells are the only cells in the body that have half the amount of chromosomes, undergo both mitosis and meiosis and in males produce the gamete, sperm.
Do germ cells undergo mitosis or meiosis?
Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg). The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization.
Why does meiosis and mitosis occur in germ cells?
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.
How many cell divisions occur during mitosis?
Mitosis is a process of cell division that results in two genetically identical daughter cells developing from a single parent cell….Comparison chart.
|Function||Genetic diversity through sexual reproduction.||Cellular reproduction and general growth and repair of the body.|
|Number of Divisions||2||1|
What type of cell division takes place in B cells?
Upon activation through the B cell receptor or Toll-like receptors, B cells rapidly divide3 and differentiate into mitotically cycling plasmablasts, post-mitotic terminally differentiated plasma cells or memory B cells4,5.
Why does meiosis and mitosis occur in germ cells Class 12?
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. It is mitosis and meiosis that ensures this cell division and organisation in a germ cell.
In which type of cell the mitosis occurs?
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.
What type of cells undergo mitosis?
Mitosis occurs in all eukaryotic animal cells, with the exception of gametes (sperm and egg), which are created by another type of cell division,…
Which type of germ cell 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.
Why do meiosis and mitosis occur in germ cells Class 12?
How is mitosis different from meiosis?
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.
