Cells Division
1 The process :

Chromosomes
In a eukaryotic cell, most of the cell's DNA is in the nucleus.
Within each species of organism, the number of chromosomes is constant.
DNA is wrapped around proteins like thread around a spool and compacted into structures called chromosomes
Cell division is involved in growth, development, and repair.
A multicellular organism grows because cell division increases the number of cells in it. As the organism develops and its cells divide, many of the cells become specialized, and most of them continue to divide.
As cells age and die, they need to be replaced
In multicellular organisms, cell division is essential for three major functions: growth, development, and repair.

3 Reproduction
Asexula
One organism produces one or more new organisms that are identical to itself and that live independently of it. The organism that produces the new organism or organisms is the parent. Each new organism is an offspring.
There are difrent tipes
-
Budding
-
Each bud forms from the parent's cells, so the bud's genetic material is the same as the parent's.
The bud grows until it forms a complete or nearly complete new organism that is genetically identical to the parent.
Regeneration
-
Although one function of regeneration is the regrowth of damaged or missing body parts, in some organisms asexual reproduction is another function of regeneration.
Sexual
Reproduction of multicellular organisms often involves sexual reproduction as well as asexual cell division
