Phases of the Cell Cycle
What is the phase of the cell cycle when the cell will divide?
M Phase
What are points in the cell cycle when a cell will 'double check' to make sure it's ready to move forward?
Checkpoints
What is the cycle of growth and cell division called?
The Cell Cycle
List the phases of cell division in order.
Prophase, Metaphase, Anaphase, Telophase
What do we call unspecialized cells, or cells that haven't differentiated yet?
Stem Cells
What is the longest phase in the cell cycle, during which the cell will grow and function?
Interphase
True or False: If space opens up next to a cell, it will not divide to fill that space.
False
In Plant cells, cytokinesis ends with the formation of a new wall of cellulose in the middle of the parent cell, called a what?
Cell Plate
At which phase do the chromosomes become visible in the cell and the nucleus begins to disappear?
Prophase
What is the process through which Stem Cells become more specialized and specific in their function and structure?
Differentiation
In what phase of the cell cycle does the DNA replicate?
S Phase
True or False: Cells that fail checkpoints will be allowed to divide.
False
Which leads to greater genetic variation and diversity: Asexual reproduction or Sexual reproduction?
Sexual reproduction
In which phase do new nuclei reform around the separated chromosomes, just before Cytokinesis?
Telophase
How can identical cells from the same organism look and function differently?
Cells can turn on and off certain genes in their DNA; this determines their function and structure.
The stage of Interphase where the cell produces Centrioles and other proteins in order to prepare for division is:
G2
What is the name for programmed cell death?
Apoptosis
In animal cells, what forms during cytokinesis when the cytoplasm is pinching off?
Cleavage Furrow
At what phase in cell division do the spindle fibers pull the chromosomes to opposite poles of the cell?
Anaphase
True or False: Once a cell si differentiated, the process CANNOT be reversed.
True
What stage of Interphase is the 'Infinite Stage' where cells will function as normal with no preparations to divide, potentially for a long time?
G0
Why will cells stop dividing once they're touching each other?
It's a physical signal to stop dividing *Answer may vary*
What happens after Mitosis, when the cytoplasm separates?
Cytokinesis
Spindle fibers attach to the centromeres and chromosomes line up in the middle of the cell during this phase of cell division.
Metaphase
What are the two types of Stem cells?
Adult Stem Cells and Embryonic Stem Cells
