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
