Cell Division and Sex-Cell Formation: Mitosis and Meiosis

TermDefinition
Chromosome Thread-like structure in a cell that contains genetic information
Mitosis Process by which a cell divides into two identical daughter cells.
Chromatid one of the identical halves that makes up a chromosome. Each chromosome is made up of two halves that have the same genetic information.
Centromere Structure that hold together each pair of chromatids
Gamete Specialized reproductive cells involved in sexual reproduction.
Diploid Cell A cell that has a double set of chromosomes... one set from each parent.
Haploid Cell A cell that contains only a single set of chromosomes.
Meiosis Process whereby special cells divide to form the sex cells. These sex cells are called haploids because they have half the number of chromosomes.
Homologous Chromosomes Description of chromosomes that occur in pairs.
Crossing Over Process by which a pair of chromosomes (homologous chromosomes) change portions of their genetic material.
