Cell Cycle-definition
|
sequence of growth & division that cells undergo
|
|
|
Three Stages- List
|
Interphase
Mitosis Cytokinesis |
|
|
Describe Interphase
|
-cell grows to mature size
-copy of DNA made -cell prepares to divide into 2 cells |
|
|
Stages of Mitosis
|
Prophase
Metaphase Anaphase Telophase |
|
|
Explain Prophase
|
-Chromatin condenses to form chromosomes
-Nuclear membrane breaks down |
|
|
Explain Metaphase
|
Chromosomes split line up across the center
|
|
|
Explain Anaphase
|
Centromeres split and the 2 chromotids seperate and move to opposite sides of the cell
|
|
|
Explain Telophase
|
New nuclear memberane forms around each region of chromosomes
|
|
|
Describe Mitosis
|
-cells nucleus divides into two nuclei
-one copy of DNA is given to each of the two daughter cells -*# of chromosomes in the parent cell= # of chromosomes in each of the two new daughter cells |
|
|
Describe Cytokinesis in an Animal Cell
|
Cell membrane pinches in at middle of cell & cell pinches in two
|
|
|
Describe Cytokinesis in an Plant Cell
|
Cell splits when a cell plate forms in center of cell, which develops into the cell wall
|
