What happens to the cell in metaphase?
chromosomes line up in the middle
100

100
What is a cancer cell?
a cell that multiplies uncontrollably
200
Where do cells get the instructions to make a new cell?
DNA
200
If a parent cell has 39 chromosomes, how many chromosomes will the cell have after interphase?

200
What are the steps of mitosis in order?
Prophase, Metaphase, Anaphase, Telophase
200
What is cytokinesis?
splitting of the cytoplasm
200
What does differentiate mean?
in reference to cells, it means they can develop into different types of cells
300
Why does your body need cells to reproduce? (2 reasons)
To grow and repair (heal)
300
What 2 things happen to the cell during interphase?
It grows and doubles the DNA
300
Which phase of mitosis is shown in the image?
300
What is the structure that develops in plant cells right before they split into 2 daughter cells?
cell plate
300
What is a stem cell?
a cell that can develop into any type of cell
400
What is the difference between chromatin, chromosomes, and chromatids?
chromatin= long strand of DNA
chromosome= condensed chromatin
chromatid= duplicated chromosome
400
What are the 3 stages of interphase in order?
G1 --> S --> G2
400
What is mitosis?
"nuclear division" or splitting of the nucleus
400
T or F: cytokinesis is a part of mitosis
False
400
What is a tumor?
A cluster of cancer cells that are multiplying uncontrollably.
500
Explain why having a lot of small cells is better than having a few large cells.
surface area to volume ratio (explain)
500
What is the difference between G1 and S phase?
G1 --> cell grows
S --> synthesize DNA
500
What 4 things are happening in the cell during prophase?
1) nuclear membrane disappears
2) chromosomes condense
3) centrioles move to opposite ends
4) spindle fibers form
500
What is the indention of an animal cell called before it divides?
cleavage furrow
500
What is the difference between a benign and malignant tumor?
benign = stays in one place
malignant = moves throughout the body
