Vocab
The genetic material in cells
DNA
A cell plate forms two new cells.
cytokinesis
The cell grows about twice its original size.
interphase
Why doesn’t mitosis occur in prokaryotes?
There is no nucleus for DNA to be replicated.
the part of the cell cycle during which the nucleus divides
Mitosis
The membrane around the nucleus breaks down.
Prophase
The chromosomes move toward the middle of the cell.
Metaphase
Why does cell division take place in single-celled organisms?
to reproduce and pass on genetic information
the life cycle of a eukaryotic cell which can be divided into 3 stages
cell cycle
The two new cells start the cell cycle again.
cytokinesis
The chromatids of each chromosome are pulled to opposite sides of the cell.
Anaphase
What is the correct order of the cell cycle?
interphase, mitosis (PMAT), cytokinesis
the division of the parent cell’s cytoplasm
cytokinesis
A new nuclear membrane forms around each group of chromosomes.
Telophase
the stage in the cell cycle during which the cell is not dividing
interphase
Which describes what happens if DNA is not duplicated during interphase?
The new cells would have an incorrect number of chromosomes.
when the chromatin is compacted into visible structures
Chromosomes
The chromatin in the nucleus condenses into chromosomes.
Prophase
At what phase does a cell spend 90% of its time?
Interphase
What occurs in a cell when it is not undergoing cell division?
It obtains food and breaks down food, uses energy, grows, excretes waste products; before cell division, it duplicates its DNA in preparation for division.
