Cell Cycle Stages Worksheet
Write the events in the correct steps of the cell cycle.
Stage
Events
G1
Interphase
Cell starts to grow

Organelles are doubled

spindle fibers attach to chromosomes
Protein synthesis

chromosomes condense into visible structures
Resting period

chromatids are pulled apart by spindle fibers
Restriction point

spindle fibers appear
S
DNA replicated

cell starts to grow
G2
Cell continues to grow

spindle fibers disappear
Nuclear membrane disappears

DNA replicated
Centrioles move toward opposite ends of cell

formation of 2 daughter cells

resting period

centrioles move toward opposite ends of cell

nuclear membrane reappears

organelles are doubled

protein synthesis

chromosomes no longer clearly visible

nuclear membrane disappears

cell membrane pinches in around nuclei

cytoplasm divided

formation of 2 nuclei

restriction point

cell continues to grow
Prophase
Spindle fibers appear
Chromosomes condense into visible structures
Metaphase
Spindle fibers attach to chromosomes
Chromosomes line up in middle of cell
Anaphase
Chromatids are pulled apart by spindle fibers
Telophase
Nuclear membrane reappears
Chromosomes no longer clearly visible
Formation of 2 nuclei
Spindle fibers disappear
Cytokinesis
Per.
Events to place in order
chromosomes line up in the middle of cell
G0
Mitosis
Name
Cytoplasm divided

Formation of 2 daughter cells
Name: ________________________
1st: Interphase

Chromosomes are doubled
2nd: Prophase




Mitotic phase begins (cell division)
Nuclear membrane disappears
Centrioles appear and begin to move to opposite
ends of the cell
Spindle fibers form between the poles


Chromosomes attach to the spindle fibers
Chromosomes line up in the middle of cell.


Centromere breaks down
Chromatids separate and move to opposite ends of
cell.


Two new nuclei form.
Mitosis ends.

Cell membrane moves inward to create two
daughter cells, each with identical nuclei
3rd: Metaphase
4th: Anaphase
5th: Telophase
6th: Cytokinesis
