Mitosis
Prophase
• Chromosomes Condense or
Thicken.
• Centrioles move to the poles (sides
they want to be the opposite of
each other.
• Spindles (fibers form)
• Nuclear envelope dissolves
releasing the chromosones

What are structures
labeled “B”?
SISTER CHROMATIDS
Uncontrolled cell
growth is the main
cause of
____________.
CANCER
Mitosis produces two new
_____________ daughter
cells.
IDENTICAL
The process that allows
stem cells to become any
other type of cell in the
body is called?
Differentiation
List the internal structures
of a chromosomes from
smallest to largest.
DNA, Nucleosome, Coil, Supercoil,
Chromosome
What is an advantage of
sexual reproduction?
Produces genetically diverse
offspring
Why is it important for
cells to stay small?
Smaller cells are more efficient
at transporting materials
into/out of the cell.
What are the three phases
of Interphase?
G1 phase, S phase, & G2 phase
The term “totipotent”
means?
Cells that can differentiate
into any type other cell or
tissue.
What is the role of spindle
fibers during mitosis?
They help separate the
chromosomes between
metaphase & anaphase.
The two stages of cell
division or M phase are?
Mitosis & Cytokinesis
Growth factors are
proteins that…
REGULATE THE CELL CYCLE
Cancer cells form masses of
cells called?
TUMORS
What is the first phase
of mitosis?
PROPHASE
What is the structure
labeled “A”?
CENTROMERE
What occurs during the “G”
phases of Interphase?
The cell grows and prepares
for division (mitosis).
During cytokinesis,
what develops in plant
cells but NOT in animal
cells?
A CELL PLATE
How long does the
ENTIRE cell cycle take?
24 hours
How long does MITOSIS
take?
80 minutes
