Cell division
|
Process by which a cell divides to form two daughter cells
|
|
|
Asexual Reproduction
|
Asexual reproduction is a form of reproduction by which offspring are produced from a single organism
|
|
|
Sexual reproduction
|
Offspring's are produced form the fusion of special reproductive cells formed by each of two parent cells
|
|
|
Chromosomes
|
Packages of DNA, that store genetic information
|
|
|
Chromatin |
Complex of chromosome and protein
|
|
|
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 during cell division
|
|
|
Prophase |
In this phase, the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
|
|
|
Centromere
|
Area where the chromatids of a chromosome are attached
|
|
|
Chromatid |
One of two identical sister parts of a duplicated chromosome |
|
|
Centrioles |
A pair of tiny structures located in the cytoplasm of an animal cell near the nuclear envelope
|
|
|
Metaphase |
Second phase of mitosis during which the chromosomes line up across the center of the cell |
|
|
Anaphase
|
Third phase of mitosis during which the chromosome pairs separate and move toward opposite poles
|
|
|
Telophase |
The last phase of mitosis, in which the chromosomes begin to disperse into a tangle of dense material. The nuclear envelope is also reforming.
|
|
|
Cyclin |
Regulate the timing of the cell cycle in eukaryotic cells
|
|
|
Growth factors |
Stimulate the growth and division of cells.
|
|
|
Apoptosis
|
A process of programmed cell death
|
|
|
Cancer
|
Disorder in which some of the body's own cells lose the ability to control growth
|
|
|
Tumor
|
Mass of cells formed by cancer cells
|
|
|
Embryo
|
A developmental stage that a living thing passes through
|
|
|
Differentiation |
The process by which cells become specialized

|
|
Totipotent
|
Cells that can develop into any type of cell |
|
|
Blastocysts
|
The inner cell mass |
|
|
Pluripotent
|
Cells that can develop not many but not all cell types |
|
|
Stem cells |
The unspecialized cells from wich
|
|
|
Multipotent |
Cells that can develop into many types of cells |
|
|
Homologous
|
Two sets of chromosomes are homologous when each of the four chromosomes from the male parent has a corresponding chromosome from the female parent |
|
|
Diploid
|
A cell that contain both sets of homologous chromosomes |
|
|
Haploid |
Cells that contain only a single set of homologous chromosomes
|
|
|
Meiosis
|
A which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell |
|
|
Tetrad
|
Tetrad in a structure that contains four chromatids
|
|
|
Crossing-over |
Crossing over produces new combinations of alleles
|
|
|
Zygote
|
A fertilized egg |
