Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Are eggs produced by mitosis or meiosis?
Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Do eggs undergo mitosis?
Egg production takes place in the ovaries. It takes several steps to make an egg: Before birth, special cells in the ovaries go through mitosis (cell division), producing identical cells. … They go through the second stage of cell division after the female goes through puberty.
What kind of cells undergo 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.
Does a fertilized egg develops further through meiosis?
Meiosis produces haploid cells. … A fertilized egg develops further through meiosis.
How many eggs are formed in meiosis?
Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg in Figure below.
Does meiosis happen after fertilization?
Meiosis occurs before fertilization.
Does meiosis 2 occur after fertilization?
Meiosis II is completed only if fertilization occurs, resulting in a fertilized mature ovum and the second polar body. So in short, the egg is stuck in metaphase II until fertilization.
What types 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,…
Can gametes undergo meiosis?
Meiosis is a process that produces gametes in sexual reproduction. Therefore, organisms that undergo sexual reproduction or feature sexual life stages undergo meiosis. Mammals produce haploid sperm and eggs through meiosis, which fuse to form a diploid zygote.
Does meiosis have Prometaphase?
Meiosis employs many of the same mechanisms as mitosis. … Meiosis II, the second round of meiotic division, includes prophase II, prometaphase II, and so on.
Why do somatic cells only undergo mitosis not meiosis?
somatic cells in animals can only undergo mitosis . Meiosis takes place in reproduction cells where the cells divide following procedural sequence.In a nutshell ,meiosis is for reproduction purposes while mitosis is for growth of new cells of other body parts ,somatic cells.
Do somatic cells undergo meiosis?
Somatic cells do not undergo meiosis, but do undergo mitosis.
What structures of the plant body undergo meiosis?
In flowering plants, meiosis occurs in megaspore mother cells (megasporocytes) within the ovules of ovaries, and in microspore mother cells (microsporocytes) within the anthers of stamens.
