Cell Division

Question 1

Somatic cell division

Answer 1

for tissue growth and repair

Question 2

Reproductive cell division

Answer 2

to produce gametes

Question 3

Gametes

Answer 3

egg and sperm cells

Question 4

Somatic cells

Answer 4

divide into mitosis and cytokinesis to reproduce themselves for tissue growth and repair

Question 5

Germ cells

Answer 5

include cells in the testes and ovaries that divide to become gametes

Question 6

Mitosis

Answer 6

refers to the separation of chromosomes

Question 7

Cytokinesis

Answer 7

refers to the division of the entire cell

Question 8

Reproductive cell division

Answer 8

produces gametes and consists of meiosis and cytokinesis

Question 9

Takes place in the testes and ovaries

Answer 9

meiosis

Question 10

Somatic stem cells

Answer 10

divide by mitosis and cytokinesis to produce smooth muscle, epithelial, nerve cells, and other cells in the body

Question 11

In the testes, divide by meiosis and cytokinesis to produce sperm cells

Answer 11

germ cells

Question 12

Grow tissues and replace dead cells and take place during wound repair

Answer 12

Mitosis and cytokinesis

Question 13

The cell cycle

Answer 13

interphase, mitosis, and cytokinesis

Question 14

Interphase

Answer 14

a phase of growth and preparation for mitosis and cytokinesis

Question 15

G1

Answer 15

The cell grows in size

Question 16

S

Answer 16

the cell makes copies of DNA (DNA replication)

Question 17

G2

Answer 17

The cell grows in size some more

Question 18

G0

Answer 18

a resting stage for cells

Question 19

Chromatin

Answer 19

cannot be seen individually under a microscope, but condense into visible chromosomes

Question 20

Genetic code

Answer 20

A, T, G, and C (Adenine’s, Thymine’s, Guanine’s, Cytosine’s) Dictates the amino acid sequence of proteins

Question 21

S phase

Answer 21

DNA is replicated in preparation for cell division

Question 22

Centromere

Answer 22

are what hold sister chromatid’s together

Question 23

Sister chromatid

Answer 23

when a chromosome is replicated

Question 24

Mitosis four main phases

Answer 24

PMAT (prophase, metaphase, anaphase, and telophase)

Question 25

Prophase

Answer 25

chromatin DNA coils up and condenses into visible chromosomes

Question 26

Metaphase

Answer 26

Mitotic spindle fibers from both sides of the cell line up in the middle

Question 27

Anaphase

Answer 27

mitotic spindle fibers contract and pull chromosomes apart to form chromatids

Question 28

Telophase

Answer 28

Cytokinesis takes place in this phase, forming new cells

Question 29

How many chromosomes do humans have

Answer 29

46
