Mitosis
Cell division in which the nucleus
divides
into nuclei containing the same
number of chromosomes
The resting phase of mitosis. Interphase
Cell grows, performs its
normal functions, and
prepares for division; consists
of G1, S, and G2 phases

G Zero (G0) Phase
Cells that have left the
cycle and cease dividing for
a long time (or permanently)
G1 Phase
The first gap, or growth phase,
of the cell cycle, consisting of
the portion of
interphase before DNA
synthesis begins.
S Phase
The synthesis phase of the
cell cycle; the portion of
interphase during which DNA
is replicated.
The second gap, or growth G2 Phase
phase, of the cell cycle,
consisting of the portion of
interphase after DNA synthesis
occurs.
Growth and preparation for
mitosis
First and longest phase of Prophase
mitosis, during which the
chromosomes become visible
and the centrioles separate
and take up positions on
the opposite sides of the
nucleus
Metaphase
Second phase of mitosis,
during which the
chromosomes line up
across the
center of the cell
Anaphase
The third phase of mitosis,
during which the
chromosome pairs
separate and move
toward opposite poles
The final phase of cell division, Telophase
between anaphase and
interphase, in which the
chromatids or chromosomes
move to

opposite ends of the cell
and two nuclei are formed.
Cytokinesis
Division of the cytoplasm
during cell division
Meiosis
Cell division that produces
reproductive cells
(gametes) in sexually
reproducing organisms
Mitosis produces two diploid (2n)
somatic cells that are genetically
Compare and Contrast identical to each other and the
Mitosis and Meiosis original parent cell, whereas
meiosis
produces four haploid (n)
gametes that are genetically
unique from each other and
the original parent (germ)
cell.
