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.
Does mitosis and meiosis occur in all animals?
In animals mitosis occurs in somatic cells and meiosis in germ cells during gamete formation, in plants mitosis occurs in all except those which produce spores by meiosis.
Do animals undergo mitosis or meiosis?
Animals spend most of their life in the diploid genetic state, and only undergo meiosis at the time of gamete production. Gametes are single cells that have no independent existence.
Where do mitosis occur in animals?
In animals mitosis for growth takes place throughout the organism until the animal is an adult and growth stops. In plants mitosis takes place throughout life in growing regions called the meristems. Replacements as cells wear out.
What is difference between meiosis and 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.
What are the similarities and differences of mitosis and meiosis?
Mitosis produces two cells from one parent using one division event. But meiosis produces four new child cells with two divisions, each of which has half the genetic material of its parent. Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells.
What happens during meiosis I?
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.
Which animal cell has already undergone meiosis?
In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Does meiosis occur in plants and animals?
In animals, meiosis produces sperm and egg, but in plants, meiosis occurs to produce the gametophyte. … The gametes merge, producing cells called zygotes that contain the same number of chromosomes as the parent plant — that is, the zygotes are diploid.
