Cell Cycle

Question 1

How many phases does the cell cycle have?

Answer 1

4

Question 2

A cell spends most of its life in this phase.

Answer 2

Interphase

Question 3

The three purposes of cell division (mitosis)

Answer 3

Growth, repair, reproduction

Question 4

Any cell in the body of an organism, except for sex cells.

Answer 4

Somatic cells

Question 5

What is the purpose of interphase?

Answer 5

Cell growth

Question 6

How many stages does interphase have?

Answer 6

3 stages

Question 7

What are the stages in interphase?

Answer 7

G1 > S > G2
(growth/gap 1 > synthesis phase > growth/gap 2)

Question 8

In this stage of interphase, the cell is busy growing and carrying out its supposed function.

Answer 8

Growth/Gap 1 (G1)

Question 9

In this stage of interphase, the cells grow too much that it no longer functions well; needing to divide. a copy of DNA is being made during this phase.

Answer 9

Synthesis Phase (S)

Question 10

In this stage of interphase, once DNA replication is complete, it enters this stage.

Answer 10

Growth/Gap 2 (G2)

Question 11

In this stage, chromatids become replicated chromosomes. further preparation for cell division happens here. it is the last and shortest part of interphase.

Answer 11

Growth/Gap 2 (G2)

Question 12

The second phase of cell cycle

Answer 12

Cell division

Question 13

Cell division occurs in…

Answer 13

Mitosis (M) phase

Question 14

The two events occurring in M phase

Answer 14

Mitosis and Cytokinesis

Question 15

The division of the cell’s nucleus, also known as nuclear division

Answer 15

Mitosis

Question 16

Division of the cell’s cytoplasm, also known as cytoplasmic division

Answer 16

Cytokinesis

Question 17

How many phases does mitosis have?

Answer 17

5

Question 18

What are the phases of mitosis in order?

Answer 18

Prophase > Metaphase > Anaphase > Telophase

Question 19

A structure inside a cell that contains genes and DNA. It serves as a storehouse of genetic information.

Answer 19

Chromosome

Question 20

This is a portion of a chromosome

Answer 20

Chromatid

Question 21

A pair of chromatids is called

Answer 21

Sister chromatid

Question 22

The exact and same copy of a chromatid

Answer 22

Homologus

Question 23

______ Protect DNA and do not include genes

Answer 23

Telomeres

Question 24

Chromosomes condense, nuclear envelope breaks down, spindle fibers form.

Answer 24

Prophase

Question 25

Chromosomes align at the cell's center, forming a metaphase plate.

Answer 25

Metaphase

Question 26

Sister chromatids separate and move to opposite poles of the cell.

Answer 26

Anaphase

Question 27

The last phase of mitosis wherein chromosome uncoils, and spindle fibers break down and dissolve. Cytokinesis then starts.

Answer 27

Telophase

Question 28

Division of the cytoplasm and organelles into two daughter cells.

Answer 28

Cytokinesis

Question 29

Having half the number (one set) of chromosomes, it has no partner.

Answer 29

Haploid

Question 30

having the full set (two sets) of chromosomes, it has a partner.

Answer 30

Diploid

Question 31

Purpose of cell division (meiosis)

Answer 31

production of gametes for sexual reproduction

Question 32

Sex cells such as egg and sperm cells are called

Answer 32

gametes

Question 33

New spindle fibers form in each haploid cell. (meiosis)

Answer 33

Prophase II

Question 34

Chromosomes align individually at the metaphase plate. (meiosis)

Answer 34

Metaphase II

Question 35

Sister chromatids separate and move toward opposite poles. (meiosis)

Answer 35

Anaphase II

Question 36

Chromatids reach the poles, nuclear envelopes reform, and cytokinesis occurs. (meiosis)

Answer 36

Telophase II

Question 37

It results in four haploid daughter cells, each genetically unique due to crossing over in Meiosis I.

Answer 37

Telophase II
