Cell Division
What's another name for cell division?
Mitosis
How many phases are in interphase?
3
In what phase does the nuclear envelope disappear?
Prophase
What is a stem cell?
A cell that can divide indefinitely and become many different cells
True or false: cells grow and divide at the same rate
False
How does sexual reproduction help improve a species' survival rate?
It mixes the genetic information
True or false: Interphase takes up less time than mitosis
False
What phase do the chromosomes line up in the middle of the cell?
Metaphase
Where do specialised cells originate from?
Stem cells
What is budding?
An outgrowth from a parent.
True or false: Multicellular organisms can reproduce asexually

What are the parts of interphase?
G1, S, G2
During what phase does the chromatin coil into chromosomes?
Prophase
What does stem cell therapy do?
It repairs organs destroyed by disease
In what process does a cell plate grow to divide the new cells?
Cytokinesis
What would happen if the cell didn't divide?
The instructions in DNA would overload, and the cells wouldn't exchange materials fast enough.
What happens during interphase?
The cell grows and duplicates organelles, the cell copies its chromosomes, and the cell checks its chromosomes.
Anaphase
How is the potential of a stem cell affected as the organism develops?
It's limited
What is apoptosis?
A built in self destruct for if cells fail a checkpoint
The DNA that's wrapped around the proteins is called...
Histones
Why is it important for the chromosomes to be copied?
So, each new cell has the same genetic information as the original cell.
In what phase do the spindle fibres disappear?
Telephase.
The cells with an embryo are...
Totipotent
How do prokaryotic cells divide?
Binary fission.
