Mitosis is required for multicellular organisms to grow. It makes new cells to replace the old ones, like hair growing, new skin, healing after cuts, and growing.
Also remember that the number of chromosomes is halfed in meiosis. You would lose data every time your cells split, quickly leading to an amount that wouldn't be able to function.
Meiosis is only used to produce gametes (sex cells). Egg/sperm cells have half the amount of chromosomes as your somatic cells (the rest of the cells in your body). When the egg and sperm fuse, they produce a zygote which now has the same number of chromosomes as the rest of your body's cells. But if that zygote went through meiosis, it would split instead of forming two daughter cells. Without mitosis, reproduction would be impossible.
What are four ways that organisms can use mitosis!! hurry i need help, im doing my science homework! thanks........ :)
No, mitosis rates differ among different organisms. It also dependent upon factor; such as cell type, loction, and the organisms need
Most multicellular organisms reproduce sexually .
Crossing over occurs in meiosis. There is no need for crossing over in mitosis.
Just above the Dermis is a layer of cells called "Stratum Basale" where mitosis is continuously happening. This helps us to keep our integumentary system up to par and able to keep microbes out in the case of a tear or cut in our skin, because our skin cells are being continually replaced.

eukaryotes reproduce by mitosis. Proaryotes reproduce via binary fission.
All organisms, leaving out a select few have to have an even amount of chromosomes because they all sexually reproduce. Therefore when they go through Meiosis and Mitosis they need a even number to reproduce. If there was an odd number in Mitosis then one chromosome instead of 46-23 or 24-12 being evenly split would have to end up being 23-11.5 with a half which isn't possible.
It doesn't need to reproduce. Reproducing is just something organisms do. The question is roughly analogous to asking "Why does water need to be liquid?" (The answer to which is, again, it doesn't need to be: being liquid is simply a property of water.)
You do need mitosis to live. If we didn't have mitosis we all would of died by now. Mitosis is the process of cell multiplication (and all the cells are identical), if we lose that ability we wouldn't be able heal cuts, for example, we would all bleed to death. Also, if our cells stopped reproducing, our internal organs would deteriorate in minutes because there is nothing to provide them with the nutrients they need to function.
sterile worker bees,mules,etc....i need some more examples other than these......
The organism that is reproducing is not doing it so that it may live, but so that its genes may be passed on. Without reproduction a population would dwindle rapidly and lead to the extinction of an entire species.
There is only one parent need in mitosis. :)
so the human race can survive by reproducing
