List the four phases of mitosis
in order
Prophase, Metaphase, Anaphase, Telophase
Identify and briefly describe each
of the parts of the cell cycle.
G1 phase, cell growth;
S phase, DNA replication;
G2 phase, preparation for mitosis;
M phase, cell division (mitosis and cytokinesis)
Describe how uncontrolled cell
division is dangerous in
organisms.
Rapidly dividing cancer cells take
nutrients away from healthy tissues. This
leads to a disruption of the proper
functioning body organs that causes
illness and may lead to death.
Which letter represent S phase of
the cell cycle
B
During which phase of mitosis
do the chromosomes line up
along the middle of the
dividing cell?
metaphase
The two main stages of cell
division are called
mitosis and cytokinesis
One difference between cell
division in plant cells and in
animal cells is that plant cells
have
a cell plate
During normal development,
the cells between toes and
fingers die by
____________________, a
process of programmed cell
death.
apoptosis
In eukaryotic cells, the timing
of the cell cycle is regulated by
cyclins
During ____________________
reproduction, cells can produce
genetically different offspring,
whereas during
____________________
reproduction, cells produce
genetically identical offspring.
sexual, asexual
Cyclins are a family of closely
related proteins that regulate
the
cell cycle
Explain the difference between
cytokinesis in plant cells and animal
cells.
In plant cells, a cell plate forms in the cytoplasm
midway between each new nucleus. The cell plate
gradually develops into a separating membrane, and a
cell wall begins to appear in the cell plate. In animal
cells, there is no cell plate. The cell membrane is
drawn inward until the cytoplasm is pinched into two
nearly equal parts.
Cancer cells form masses of
cells called
tumors
__________ is a disorder in
which some cells have lost the
ability to control their growth
rate
Cancer
During early development, all
cells in the embryo of a
multicellular organism are
identical. Later on in
development, the cells will
become specialized through a
process called
differentiation.
Centrioles duplicate during
which phase of the cell cycle
interphase
Mitosis is a form of
_________ reproduction,
because the daughter cells that
form are identical to the parent
cell.
asexual
Interphase is represented by which
letters
A,B,C
Most of a cell’s growth takes
place during the ______ phase
of the cell cycle.
G1
When during the cell cycle is a
cell’s DNA replicated?
S phase
During ____________, a cell
undergoing cell division finally
splits into two daughter cells.
cytokinesis
the role of the
__________during mitosis is
to help separate the
chromosomes.
spindle fibers
___________is a disorder in
which some of the body’s cells
lose the ability to control
growth and division.
Cancer
An advantage of sexual
reproduction over asexual
reproduction is that sexual
reproduction
provides genetic diversity
Cell division occurs in two
main stages, the first of which
is called
_____________________.
mitosis
Prokaryotes reproduce by an
asexual process known as
_________________.
binary fission
Which type of reproduction, sexual or
asexual, is best suited for organisms
that live in a place where
environmental conditions are stable?
And Why
Because the offspring of asexual reproduction
are genetically identical to parents, they have the
characteristics that help them survive in the
conditions in which the parent cells survived.
They might not have characteristics to survive
should the conditions change.
The process by which a cell
divides into two daughter cells
is called
cell division
During normal mitotic cell
division, a parent cell that has
eight chromosomes will
produce two daughter cells,
each containing
eight chromosomes.
During which phase in the cell
cycle does mitosis happen?
M phase
