cell division

Question 1

cell cycle

Answer 1

average amount of time it takes a cell to go through all stages of cell’s life
Most cell functions are not related to cell division
Cell division will occur in most cells

Question 2

mitosis

Answer 2

cell division of body cells (every cell in the body except reproductive cells)

Question 3

meiosis

Answer 3

cell division of reproductive cells
Only occurs in ovaries and intestines

Question 4

Stages of the cell cycle

Answer 4

interphase
G1
G0
S
G2
Mitosis

Question 5

interphase

Answer 5

all steps of cell cycle except mitosis

Question 6

G1

Answer 6

cell growth and differentiation - need to specialize

Question 7

G0

Answer 7

a non dividing cell phase
- can be short term or indefinite

Question 8

S

Answer 8

synthesis of DNA
- replicate all DNA of cell so when cell division occurs, each cell has a complete set

Question 9

G2

Answer 9

more cell growth and preparation for cell division
