Asexual reproduction in one-celled organisms is considered ______ ______ (a form of mitosis).

binary fission

Cell growth

G1 (Gap 1) -

Replication DNA

S (DNA Synthesis)

Growth and preparation for mitosis

G2 (Gap 2) -

Cell division

M (mitosis)

Stops growth

G0 (G Zero)

An example of a cell that hits the G0 stage and stops growing and does not proceed in the cell cycle:

neurons

An example of a cell that hits the G0 stage and stops growing and does not proceed in the cell cycle:

Tumors

A. (Includes B, C, and D; "cell resting")

Interphase

first stage of cell cycle - cell grows

G1

DNA is copied/replicated

S

cell prepares to divide

G2

first stage of cell division

prophase

second stage of cell division

Metaphase

third stage of cell division

Anaphase

fourth stage of cell division

telophase

name for NUCLEAR division of cell division:

M

name for CYTOPLASMIC division of cell division:

Cytokinesis

Cytokinesis for PLANT CELLS - cell walls form from in to out

Cell plate formation

Cytokinesis for ANIMAL CELLS - cell membranes form from out to in

Cleavage Furrow

Chromatids of each chromosome separate at the centromere.

anaphase

Copied DNA coils into chromosomes.

Telophase

Spindle fibers disassemble (disappear).Centrosomes appear next to the disappearing nucleus.

Prophase

Kinetochore fibers move chromosomes to the cell's center.

Metaphase

A nucleus and nucleolus reform in each new cell.

Telophase

Chromatids move towards opposite poles of the dividing cell.

Anaphase

Spindle fibers radiate from the centrosomes.

Prophase
