Cell Division
Mitosis is the process of cell division. In animals, cell division is mainly restricted to replacement and repair. In plants, many cells keep the ability to differentiate.
Meiosis is a type of cell division that produces gametes. During sexual reproduction it allows the child the same numbers of genes as their parent. It helps generate variation through the crossing over of chromosomes and more mutations.
A chromosome is a threadlike structure found in the nucleus of a cell, holds the genetic information.
DNA- the material which makes up genes and chromosome, the carrier of genetic information.
