They must reduce their number of chromosomes by half so that way when they do fuse, the two halves of genetic material equal a full cell.
Before mitosis, cells have a diploid number of chromosomes, which means they have 46 chromosomes in humans. After mitosis, the daughter cells also have a diploid number of chromosomes, so they also have 46 chromosomes.
A giraffe's somatic cells, such as heart cells, will also have 31 chromosomes. This is because all cells in an organism's body carry the same set of chromosomes, with the exception of sex cells (gametes) which undergo meiosis to reduce their chromosome number by half.
They copy their chromosomes so that when they do divide into two different cells each one will have its own set of chromosomes and it couldn't be copied and transferred after divison occured
There are 46 chromosomes in your body cells. The egg cells have half the amount of chromosomes as the body cells, so there are 23 chromosomes in the egg cells.
Yes

Body cells are the only cells that go through the process of mitosis. So body cells have 46 chromosomes or 23 chromosome pairs. Before the cells separate the chromosomes duplicate and split so that the new cell has an identical DexyriboNucleicAcid.
Cells are not found in chromosomes. Chromosomes are found in cells.
Yes there are chromosomes in animal cells. There are also chromosomes in plant cells. :)
They are in need of reproduction.
Twice the number in the cell. So if the cell normally has 46 chromosomes, such as in somatic human cells, the dividing cell would have 92 chromosomes just before division. With germ cells such as sperm and egg this would be half that. Sperm and egg cells in humans would contain 23 chromosomes and 46 just before division.With N representing the number of chromosomes in an organism:Mitosis (somatic cells) 2N -> 4N division -> 2N
So that the new cells have the same chromosomes as the parent cells.
chromosomes are in cells
A cell undergoing mitosis has twice the usual number of chromosomes for that species. For example, human body cells have 46 chromosomes, but after DNA replication, which must occur before mitosis, a human body cell will have 92 chromosomes.
