Cell Cycle & Mitosis

Question 1

2 reasons cells have to divide

Answer 1

dna overload
small surface area to volume ratio

Question 2

what does DNA overload mean

Answer 2

The larger the cell gets, the more demands it puts on its resources, forcing it to divide into two daughter cells

Question 3

what does surface area represent

Answer 3

cell membrane

Question 4

what does cell volume represent

Answer 4

cytoplasm

Question 5

adaptations for greater surface area volume ration

Answer 5

cell division, slower metabolism, change shape

Question 6

what is the cell cycle

Answer 6

series of events that allow cells to divide

Question 6

two main stages of cell division

Answer 6

mitosis
cytokinesis

Question 7

4 stages of the cell cycle

Answer 7

G1
S
G2
M phase

Question 8

how much of a cells time in spent in interphase

Answer 8

90%

Question 9

4 stages of mitosis

Answer 9

prophase
metaphase
anaphase
telophase

Question 10

differentiate between chromatin and chromosome

Answer 10

chromatin: loosely coiled, squiggles, unorganized, interphase, electron
chromosome: super coiled, X, organized, cell division, light

Question 11

how many chromosomes are found in human body cells

Answer 11

46

Question 12

proteins that regulate timing of cell cycle

Answer 12

cyclins

Question 13

define cancer

Answer 13

uncontrollable cell growth and division

Question 14

what is apoptosis

Answer 14

programmed cell death
