cell division
process by which a cell divides into two new daughter cells
asexual reproduction
process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
sexual reproduction
type of production in which cells from two parents unite to form the first of a new organism
chromosome
threadlike structure within the nucleus that contains genetic information that is passed from one generation to the next
chromatin
substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
cell cycle
series of events in which a cell grows, prepares for division, and divides to form two daughter cells
interphase
period of the cell cycle between cell divisions
mitosis
part of eukaryotic cell division during which the cell nucleus divides
cytokinesis
division of the cytoplasm to form two separate daughter cells
prophase
first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
centromere
region of a chromosome where the two sister chromatids attach
chromatid
one of two identical "sister" parts of a duplicated chromosome
centriole
structure in an animal cell that helps to organize cell division
metaphase
phase of mitosis in which the chromosomes line up across the center of the cell
anaphase
phase of mitosis in which the chromosomes separate and move of opposite ends of the cell
telophase
phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
