Mitosis Phases
Cell Cycle Numbers
Why Cells Divide
Parts of Division
Cell Cycle Errors
200
During this stage of mitosis, chromosomes first become visible as they condense.
What is Prophase?
200
Each daughter cell contains this many chromosomes, for each chromosome the parent cell had.
What is One?
200
True or false, cell division does not allow organisms to grow in size.
What is false?
200
This structure forms during division and helps pull chromosomes apart.
What are spindle fibers?
200
This happens when cells divide uncontrollably instead of stopping when they should.
What is Cancer?
400
In this stage of mitosis, chromosomes line up in the center of the cell.
What is Metaphase?
400
This many daughter cells are produced during cellular division.
What is Two?
400
Cells divide to replace cells that are this.
What is damaged? or What is Dead?
400
Prokaryotic cells divide through this process.
What is Binary Fission?
400
An error during cell division that causes cells to end up with too many or too few chromosomes.
What is Nondisjunction?
600
Prophase, Metaphase, _______, and Telophase are the stages of mitosis.
What is Anaphase?
600
Each cell divides this many times in each cell cycle.
What is One?
600
In single-celled organisms, cell division is used as a method of making new organisms.
What is asexual reproduction?
600
These structures hold sister chromatids together until they separate.
What are centromeres?
600
When cell cycle checkpoints fail, damaged DNA can be this instead of fixed.
What is copied and passed on?
800
This cell is currently is this phase of mitosis.
What is Metaphase?
800
Human cells have this many chromosomes.
What is Forty Six?
800
Cells divide to copy and pass on this important biological information.
What is DNA?
800
This structure in animal cells helps organize spindle fibers during cell division.
What are centrioles?
800
This type of mistake can occur when DNA is not copied correctly during interphase.
What is a Mutation?
1000
Spindle fibers disappear in this phase.
What is Telophase?
1000
This many chromatids make up a chromosome.
What is Two?
1000
This benefit of cell division helps tissues keep working properly over time.
What is maintaining homeostasis?
1000
This part of the chromosome is where spindle fibers attach.
What are Centromeres?
1000
Failure of this control system can allow abnormal cells to keep dividing.
What are cell cycle checkpoints?
