Chapter 6 - The Cell Cycle
|
Why Do Cells Divide?
Interphase (longest part of the cell cycle)
|
 |
Mitosis
- nuclear division, number of chromosomes remains the same
Lets Break It Down
 |
Interphase (technically not part of mitosis, but it is included in the cell cycle) Cell is in a resting phase, performing cell functions DNA replicates (copies) Organelles double in number, to prepare for division |
 |
Prophase Spindle forms Centrioles move to opposite poles Chromosomes become visible |
 |
Metaphase Chromosomes line up along the equator |
 |
Anaphase Centromeres divide Chromatids separate and move to opposite poles |
 |
Telophase Nuclear membrane forms around each group of chromosomes Chromosomes unwind Cytokinesis begins |
Cytokinesis
The process by which the cytoplasm divides and one cell becomes two individual cells. The process is different in plants and animals
Animals - cell pinches inward
Plants - a new cell wall forms between the two new cells
