Mitosis is used for several purposes
1. Growth. the embryo increases in size due to mitosis. Enlargement of the embryo, young child and growth during puberty is due in part to increasing the number of cells.
2. Repair. If you cut yourself, or an incision is made during surgery, the hole is closed by cells dividing to close the space created by the wound.
3. Replacement. Some cells wear out rapidly (blood - 90-120 days; skin - 2 weeks; intestine 2.5 days) these old and worn out cells need to be replaced on a constant basis
4. Reproduction - protists that undergo mitosis have produced two identical cells and thus have reproduced
5. Cancer - unfortunately cancer is mitosis of cells that we don't want to be undergoing mitosis.
Meiosis
is used to produce the sperm and the egg each of which have half the number of chromosomes as the starting cell. This is so that when a sperm fertilizes an egg the total number of chromosomes is equal to that in any other cell
What else can I help you with?
Must mitosis occur in budding?
Mitosis must occur in budding.
Who does mitosis occur before cells divide?
WHO does mitosis occur? GRAMMAR FAIL YOU ARE SO DUMB
What does not occur in plants cell mitosis but does occur in animal cell mitosis?
Astral rays does occur in animal cells not in plant cell
What is the function of chromosome changes that occur in mitosis?
These changes usually occur in meiosis not mitosis. It causes a mixing of the alleles.
Does mitosis occur in animals?
yes. mitosis is used in cell division
Did nuclear division occur in mitosis or in intrphase?
4 I think
Does cell replacement occur in mitosis or meiosis?
Its meiosis. Mitosis is cell division.
Where does mitosis and meisosis occur?
In the mitochondria
What is mitosis and why does it occur?
blue waffle
Must spores occur in mitosis?
Spores are produced through a specialized form of cell division called meiosis, not mitosis. Meiosis involves two rounds of cell division that results in the formation of haploid spores with half the number of chromosomes as the parent cell. These spores will eventually undergo mitosis to form new multicellular organisms.
What point in mitosis does cytokinesis occur?
Mitosis occurs during the last phase- Telophase.
Does mitosis occur in the phloem?
No, mitosis does not occur in the phloem. Mitosis is the process of cell division, and in the phloem, specialized cells called sieve elements are responsible for transporting sugars. These sieve elements are formed via a process called differentiation, not mitosis.
