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.
