Miller & Levine Ch. 11 Cell Growth & Division

undifferentiated cells found among differentiated cells in a tissue or organ

The microtubules of the spindle apparatus begin to shorten, the sister chromatids separate, the chromosome move toward the poles of the cell

programmed cell death

process of reproduction involving a single parent that results in offspring that are genetically identical to the parent

Microtubules and fibers that radiate out from the centrioles.

A form of asexual reproduction in which one cell divides to form two identical cells.

the uncontrolled growth and division of cells.

cells reproduce by a cycle of growing and dividing

Process by which a cell divides into two new daughter cells

Cell organelle that aids in cell division in animal cells only

the structure of at the center of the chromosome where the sister chromatids are attached

A structure in animal cells containing centrioles from which the spindle fibers develop.

one half of a duplicated chromosome

the relaxed form of DNA in the cell's nucleus

the structures that contain the genetic material that is passed from generation to generation of cells

one of the specific proteins that regulates/stimulates the cell cycle

the method by which a cell's cytoplasm divides creating a new cell

stem cell that can give rise to all types of cells in the body

In interphase - cell grows rapidly, builds new organelles; also performs regular cell functions

Stages of Interphase

The final period of interphase during which the cell prepares for mitosis.

the stage during which the cell grows, carries out cellular functions, and replicates its DNA in preparation for the next stage of the cycle. Cell spends most of its time here.

Sister chromatids are pulled along the spindle apparatus toward the center of the cell, they line up in the middle of the cell

Thick hollow tubes that make up the cilia, flagella, and spindle fibers.

the stage of the cell cycle during which the cell's nucleus and nuclear material divide

the first stage in mitosis- the longest phase- in this stage the cell's chromatin condenses into chromosomes and the nuclear envelope disappear.

Stages of mitosis (hint: PMAT)

The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.

A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents

are structures that contain identical copies of DNA.

structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides

Unspecialized cells that can develop into specialized cells when under the right conditions

The chromosomes arrive at the poles and begin to relax, two new nuclear membranes begin to form and the nucleoli reappear, the spindle apparatus dissembles.
