Interphase
|
"Growth phase"
1. Proteins/nutrients taken in 2. New organelles produced 3. Cell membrane grows 4. Chromosomes duplicate |
|
Centromere
|
Where sister chromatids are joined
|
|
Chromatid
|
An individual strand of a duplicated chromosome
|
|
Mitosis
|
The process in which chromatids are pulled apart and move to opposite ends of the cell
|
|
Cell division (cell reproduction)
|
Mitosis + cytokinesis
|
|
Cytokinesis
|
Cytoplasm and organelles divide into roughly equal halves and the cell splits into two
|
|
Prophase
|
1. Chromosomes condense
2. Centrioles move to the ends of the cells 3. Nuclear membrane disappears 4. Spindle fibres join to centromeres |
|
Metaphase
|
Tug-of war occurs to line up chromosomes along the middle of the cell
|
|
Anaphase
|
Sister chromatids separate and spindle fibres pull one to each end of the cell
|
|
Telophase
|
1. Spindle fibres disappear
2. Nuclear membranes form around each set of chromosomes 3. Chromosomes uncoil |
|
Meiosis
|
Two cell divisions that result in four daughter cells each containing 1/2 of the number of chromosomes
|
|
Prophase I
|
1. Chromosomes condense
2. Nuclear membrane disappears 3. Spindle forms |
|
Metaphase I
|
Pairs of homologous chromosomes line up along middle of the cell
|
|
Anaphase I
|
One from each pair of homologous chromosomes is pulled to each end of the cell
Chromatids stay attached at the centromere |
|
Telophase I
|
1. Paired chromatids uncoil
2. Nuclear membrane forms around each 3. Spindle disappears 4. Cytokinesis occurs |
|
Prophase II
|
1. Paired chromatids condense
2. Nuclear membrane disappears 3. Spindle forms |
|
Metaphase II
|

|
|
Anaphase II
|
Chromatids pulled apart and pulled to opposite ends of the cell
|
|
Telophase II
|
1. Chromosomes uncoil
