|
Chromosome
|
Cell structures that carry the genetic material that is copied and passed from generation to generation of cells
|
|
|
Chromatin
|
Long strands of DNA found in the eukaryotic cell nucleus condense to form chromosomes
|
|
|
Cell Cycle
|
Continuous sequence of growth (interphase) and division (mitosis) in a cell
|
|
|
Interphase
|
Cell growth phase where a cell increases in size carries on metabolism and duplicates chromosomes prior to division
|
|
|
Mitosis
|
Period of nuclear cell division in which two daughter cells are formed each containing a complete set of chromosomes
|
|
|
Prophase
|
First and Longest phase of mitosis where chromatin coils into visible chromosomes
|
|
|
Sister Chromatid
|
Identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis the halves are held together by a centromere
|
|
|
Centromere
|
Cell structure that joins two sister chromatids of a chromosome
|
|
|
Centriole
|
In animal cells a pair of small cylindrical structures composed of microtubules that duplicate during interphase and move to opposite ends of the cell during prophase
|
|
|
Spindle
|
Cell Structures composed of microtube fibers forms between the celltrioles during prophase and shorten during anaphase pulling apart sister chromatids
|
|
|
Metaphase
|
Short second phase of mitosis where doubled chromosomes move to the equator of the spindle and chromatids are attached by centromeres to a seperate spindle fiber
|
|
|
Anaphase
|
Third phase of mitosis in which the centromers split and the chromatid pairs of each chromosome are pulled apart by microtubules
|
|
|
Telophase
|
Final phase of mitosis during which new cells prepare for their own independent existence
|
|
|
Cytokinesis
|
Cell process following meiosis or mitosis in which the cell's cytoplasm divides and seperates into new cells
|
|
|
Tissue
|
Groups of cells that work together to preform a specific function
|
|
|
Organ
|
Group of two or more tissues organized to preform complex activities within an organism
|
|
|
Organ System
|
Multiple organs that work together to preform a specific life function
|
