The division of the cytoplasm of the cell during cell division is referred to as_____________.
Cytokinesis
200
What is the longest phase in the cell cycle?
Interphase
200
True or False: Cytokinesis is included in the phases of mitosis.
False
200

4

200
At which phase do the chromosomes become visible in the cell?
Prophase
200
What is the end result of cytokinesis?
Two identical daughter cells
300
The cell cycle results in two genetically _________ cells.
Identical
300
True or False: Interphase is not included in the phases of mitosis.
True
300

In what cells does Meiosis occur?

Reproductive cells

300

In which phase does the nuclear membranes reform around the separated chromosomes?

Telophase

300
True or False: Cytokinesis is the division of the cell nucleus.
False. Cytokinesis is the division of the cytoplasm. Mitosis is the division of the nucleus.
400
The cell cycle state where the cell grows to its full size, copies the DNA and organelles and prepares to divide is called the ________________.
Interphase
400

True or False: Mitosis is asexual reproduction and the parent cells are identical to the daughter cells.

True

400

How many chromosomes are in human REPRODUCTIVE cells?

23 (half of 46 in body cells)

400
At what phase in cell division do the spindle fibers pull the chromosomes to opposite poles of the cell?
Anaphase
400

In an animal cell, how do the two cells separate?

Pinch apart

500

What is the importance of the cell cycle to multicellular organisms with respect to tissue repair?

The cell cycle replaces damaged, worn, and aging cells

500
List the phases of mitosis in order.
Prophase, Metaphase, Anaphase, Telophase

What is an advantage of sexual reproduction (2 parents) over asexual reproduction (1 parent)?

More genetic variety

500

Spindle fibers attach to the centromeres and chromosomes line up in the middle of the cell during this phase of cell division.

Metaphase

500
In plant cells, a _______________ is built between the two daughter cells as they pull apart during cytokinesis.
Cell plate
