Cell Cycle Match Activity
Instructions:
1. Read the description of the phases of the cell cycle.
2. Match each description with the appropriate picture.
3. Place the description and illustration in the appropriate spot along the side of the
cell cycle diagram provided by your teacher. Use the arrows as pointers to
identify specific stages in the cell cycle.
Description
During this phase of the cell cycle, the chromatids are pulled
apart at the centromere by the spindle fibers. The spindle
fibers contract and pull the chromatids to opposite sides of the
cell. This phase is part of the M phase.
During this phase of the cell cycle, the DNA in the nucleus
undergoes replication. An exact copy of DNA is produced to
ensure that the new cell has all of the information it needs to
function properly. This phase is part of interphase.
This is the last step of mitosis, and the duplicated
chromosomes arrive at opposite ends of the cell. The nuclear
membrane forms around each set of chromosomes. The DNA
within each chromosome uncoils and the nucleolus reappears.
Two nuclei are produced that contain a complete set of
chromosomes that are identical to the parent cell. The
cytoskeleton reforms and duplicated organelles move to
opposite sides.
During this phase of the cell cycle, the cell enters a second
period of growth. During this phase, the cell makes proteins
and other molecules. This phase is part of interphase. One of
the molecules initiates the last phase of the cell cycle, cell
division.

During this phase of the cell cycle, the thin strands of DNA
become shorter and thicker as they condense. The
chromosomes condense and become visible. Centrioles
migrate toward opposite sides of the cell, and spindle fibers
begin to form. Towards the end of this phase, the nuclear
membrane breaks down and the nucleolus disappears. This
phase is part of the M phase.
Finally, the cytoplasm divides to produce two identical daughter
cells. In animal cells, the cytoplasm pinches in the middle
forming two cells. In plant cells, a cell plate forms between the
two nuclei. The cell plate develops into a cell wall.
Cells often pause in this sub-phase of G1 and continue normal
metabolic activities before being triggered to divide again.
Fully differentiated cells, such as muscle and nerve cells,
remain in this sub-phase for the life of the cell.
During this phase of the cell cycle, spindle fibers attach to the
centromers of each chromosome and move them towards the
middle of each cell. This phase is recognizable as the
chromosomes become aligned at the cell’s equator. This phase
is part of the M phase.

During this phase of the cell cycle, the cell begins to grow. The
cell is active with chemical reactions that occur within the
cytoplasm. Towards the end of this phase, the organelles are
duplicated. This phase is part of interphase.
