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 calleddifferentiation.
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 lettersA,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
