Cell Cycle, Cell Division, and Reproduction Terms

Term Definition

Cell Cycle

The series of events involving the growth, replication, and division of a cell.

centromere

where chromatins are joined in a duplicated chromosome
Double Helix shape of DNA, looks like a twisted ladder
Germ cells The reproductive cell of any sexually reproducing organism Also called a SEX cell.
Somatic cells Any cell of a sexually reproducing organism that is not a germ cell. Also called a BODY cell.
Interphase The first stage in the cell cycle in which the cell grows and the DNA replicates (makes a copy of itself).
Meiosis A series of stages in the cell cycle of a germ (sex) cell in which the parent cell divides into 4 new daughter cells that are NOT identical to the parent cell.
Daughter cell Either of the two (or 4) cells formed when a cell undergoes cell division by mitosis (or meiosis).
Gene Hereditary Unit
Mitosis A series of stages in the cell cycle of a somatic (body) cell in which the parent cell divides into 2 new daughter cells that are identical to the parent cell.

Chromatin

one of a pair of duplicated chromosome

Reproduction The process by which organisms sexually or asexually generate new individuals of the same kind

Parent cell

A cell that is the source of other cells, as a cell that divides to produce two or more daughter cells.
