Mitosis & Meiosis
14 Words
Exchange of chromosomal segments between a pair
of homologous chromosomes during prophase I of meiosis.
(Genetic variety)
Crossing Over
Exchange of chromosomal segments between a pair
of homologous chromosomes during prophase I of meiosis.
(Genetic variety)
Third main stage of the cell cycle, during which the
cell’s cytoplasm divides, creating a new cell.
Cytokinesis
Third main stage of the cell cycle, during which the
cell’s cytoplasm divides, creating a new cell.
First stage of mitosis, during which the cell’s chromatin condenses into chromosomes
(Nucleus disappears
& Chromosomes become visible).
ProphaseFirst stage of mitosis, during which the cell’s chromatin condenses into chromosomes
(Nucleus disappears
& Chromosomes become visible).
Cell with half the number of chromosomes (n) as a diploid (2n) cell.
(Sperm & eggs)
HaploidCell with half the
number of chromosomes (n) as a diploid (2n) cell.
(Sperm & eggs)
Second state of the cell cycle during which the cell’s
replicated DNA divides and two genetically identical
diploid daughter cells are produced.
MitosisSecond state of the cell cycle
during which the cell’s replicated DNA divides and
two genetically identical diploid daughter cells are
produced.
Asexual form of reproduction used by some prokaryotes in which a cell divides into two genetically identical cells.
(How bacteria reproduce)
Binary Fission
Asexual form of reproduction used by some prokaryotes in which a cell divides into two genetically identical cells.
(How bacteria reproduce)
Second stage of mitosis in which motor proteins pull sister chromatids to
the cell’s equator (middle)
MetaphaseSecond stage of mitosis
in which motor proteins pull sister chromatids to
the cell’s equator (middle)
A haploid sex cell, formed during meiosis, that can combine with another haploid sex cell and produce a diploid fertilized egg.
(Sperm & eggs)
GameteA haploid sex cell, formed
during meiosis, that can combine with another haploid sex cell and produce a diploid fertilized egg.
(Sperm & eggs)
Process of cellular reproduction, occurring in
three main stages –
Interphase (growth), mitosis (cell division), and
cytokinesis (cytoplasm division)
Cell CycleProcess of cellular
reproduction, occurring in three main stages –
Interphase (growth), mitosis (cell division), and
cytokinesis (cytoplasm division)
Reduction division process, occurring only in reproductive cells (sperm & eggs), in which one diploid (2n) cell produces four haploid (n) cells that are
not genetically identical.
MeiosisReduction division process,
occurring only in reproductive cells (sperm & eggs), in which one diploid (2n) cell produces four haploid (n) cells that are
not genetically identical.
Third stage of mitosis in which sister chromatids are pulled apart
and microtubules, along with motor proteins, move the
chromosomes to opposite poles of the cell.
(Chromosomes move across the cell)
AnaphaseThird stage of mitosis in which
sister chromatids are pulled apart and microtubules, along with
motor proteins, move the chromosomes to opposite poles of
the cell.(Chromosomes move across the cell)
Having two copies of each
chromosome (2n).(Body/Somatic Cells)
DiploidHaving two copies
of each chromosome (2n).
(Body/Somatic Cells)
First stage of the cell cycle, during which a
cell grows, matures, and replicates it DNA.
InterphaseFirst stage of the cell cycle, during which a
cell grows, matures, and replicates it DNA.
Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet
completely divided.
TelophaseLast stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet
completely divided.
