Cell Division Quiz

Question 0

What are the three positives of asexual reproduction

Answer 0

Very fast
Energy sufficient
Makes a lot of offspring

Question 1

Why cell division?

Answer 1

To support bodily function
To heal
To reproduce
To replenish dead cells

Question 2

What is the negative of asexual reproduction Ct

Answer 2

If it dies all are likely to die too: no variation

Question 3

What are the three negatives of sexual reproduction

Answer 3

Slow
Not energy sufficient
Fewer offspring

Question 4

What is the positives of sexual reproduction

Answer 4

Unique: genetic variation

Question 5

Cell division happens in (what kind of cells)?

Answer 5

Somatic (body) cells and not germ (sex) cells

Question 6

In eukaryotic cells what are the two main stages of cell division

Answer 6

Mitosis and cytokinesis

Question 7

Reproduction by mitosis is classified as

Answer 7

Asexual since the cells produced by mitosis are genetically identical to the parent cell

Question 8

What are chromosomee

Answer 8

In eukaryotic cells the genetic information that is passed on from one generation of cells to the next is carried by chromosomes

Question 9

What are chromosomes made up of

Answer 9

DNA and proteins

Question 10

When are chromosomes visible in most cells

Answer 10

During cell division

Question 11

What are chromatids

Answer 11

Well before cell division, each chromosome is replicated, or copied. Because of this, each chromosome consists of two identical sister chromatids

Question 12

Each chromatid is attached to an area called the

Answer 12

Centromere

Question 13

Define centromere

Answer 13

Centromere’s are usually located near the middle of the chromatids, although some line near the ends

Question 14

Period of growth in between cell divisions is called

Answer 14

Interphase

Question 15

What occurs during the cell cycle

Answer 15

During the cell cycle the cell grows, prepares for division, and divides to form two daughter cells, each of which then begins the cycle again.

Question 16

Which phase occurs in the M phase?

Answer 16

Mitosis and cytokinesis

Question 17

Which phases occur during the S-phase

Answer 17

Chromosome replication or synthesis. When the cell copies of chromosomes it makes a duplicate set of DNA

Question 18

Which phases are between the M and S phases?

Answer 18

G1 and G2

Question 19

What are the g1 and g2 phases?

Answer 19

They are actually periods of intense growth and activity

Question 20

Interphase is divided into three phases:

Answer 20

G1 S and G2

Question 21

What occurs in the G1 phase

Answer 21

Growth: cells increase in size and synthesize new proteins and organelles

Question 22

What occurs during the S phase?

Answer 22

Chromosomes are replicated and the synthesis of DNA molecules take place. Key proteins associated with the chromosomes are also synthesize

Question 23

What happens during the G2 phase

Answer 23

Many organelles and molecules required for Cell division are produced. When it’s completed the cell is ready to enter the M phase and begin the process of cell division

Question 24

What are the four phases of mitosis

Answer 24

Prophase Metaphase Anaphase Telophase

Question 25

What are centrioles

Answer 25

Two tiny structures located in the cytoplasm near the nuclear envelope at the beginning of prophase

Question 26

What is the spindle

Answer 26

A fanlike microtubule that helps separate the chromosomes

Question 27

Define prophase

Answer 27

The chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down

Question 28

Define metaphase

Answer 28

The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere

Question 29

Define anaphase

Answer 29

The sister chromatids separate into individual chromosomes and are moved apart

Question 30

Define telophase

Answer 30

The chromosomes gather at opposite ends of the cell and lose their distinct shapes. 2 new nuclear envelopes will form

Question 31

Define cytokinesis

Answer 31

The cytoplasm pinches in half. Each daughter cell has not dental set of duplicate chromosomes

Question 32

How does cytokinesis occur in most animal cells

Answer 32

The cell membrane is drawn in word into the cytoplasm is pinched into two nearly equal parts

Question 33

What forms midway between the divided nucleus during cytokinesis in plant cells

Answer 33

A structure known as the cell plate

Question 34

Mitosis is division of the

Answer 34

Nuclei
