Interphase
What is approximately 90-95%?
Chromosomes begin to condense and they become visible
What happens to the chromosomes?
Where the chromosomes line up
What is in the middle of the cell?
This separates in the cell
What are sister chromatids?
This forms around the chromosomes
This is when DNA is copied
What is the S phase?
The nuclear membrane begins to break down
What happens to the nuclear membrane?
This lines the chromosomes up
What are spindle fibers?
Where the chromosomes move
What is to the opposite ends (or poles) of the cell?
What is beginning to uncoil?
This stage is divided into G1, S, and G2
What is Interphase?
Spindle fivers begin to form
What happens to spindle fibers?
The function of the middle of the cell
What is to mark where chromosomes align?
This happens to the sister chromatids
What is being pulled apart?
This is how many nuclei form
The cell is preparing for mitosis during this part of interphase
What is the G2 Phase? (second gap phase)
This structure breaks down so spindle microtubules can access the chromosomes
What is the nuclear envelope?
This is how many sister chromatids are present during this stage
What is 92 chromatids? (each chromosome has been duplicated during S phase and has two identical sister chromatids for mitosis)
The spindle poles move further apart from each other and the cell's length is elongated
What is Anaphase B (Spindle pole separation)?
Unlike animal cells, plant cells cannot divide by pinching inward because of this rigid structure
What is the cell wall?
This stage takes up most of a cell's life
What is the G1 phase?
These structures organize the microtubules and move towards opposite poles in animal cells
What are centrosomes?
This is what ensures the cell divides by blocking the transition from metaphase to anaphase until every chromosome is aligned properly at the metaphase plate
What is the spindle/Metaphase checkpoint?
The sister chromatids separate and move towards opposite spindle poles
What is Anaphase A (chromosomes move to different poles)?
Animal cells begin forming a cleavage furrow, while plant cells begin forming this structure
What is a cell plate?
