Biology Quiz

Question 0

When does mitosis begin?

Answer 0

Right after interphase.

Question 1

What are the 3 phases of interphase?

Answer 1

G1, S, G2

Question 2

How are chromatid pairs held together?

Answer 2

By centromere

Question 3

The cell only carries out normal/everyday activities in which phase? (Such as growth)

Answer 3

G1

Question 3

How long can the G1 phase last?

Answer 3

days to years

Question 6

What does the S phase do?

Answer 6

It gives cells enough material to fully supply 2 cells after division.

Question 7

How many phases in a cell cycle?

Answer 7

4

Question 8

When does G2 phase begin?

Answer 8

Once the cell has replicated it’s genetic material.

Question 9

What is G2 phase?

Answer 9

Cellular organelles are produced to supply the new cells.

Question 10

Name a few cell organelles that supply new cells…

Answer 10

Mitochondria, Ribosomes, Organelles

Question 11

What is mitosis?

Answer 11

Nuclear division.

Question 12

What is G1?

Answer 12

Resting stage of the cell.

Question 13

When does the S phase begin?

Answer 13

When surface area to volume imbalance occurs.

Question 13

What does mitosis do?

Answer 13

Mitosis focuses on genetic material of cells & spindle fibers began to appear. (Opposite ends)

Question 14

What happens in prophase?

Answer 14

1. Nucleus starts to disappear.

2. Chromatin pairs AKA sister chromatids are formed.

Question 15

What is cytokinesis?

Answer 15

The splitting of cells.

Question 16

What does chromatin do?

Answer 16

Pulls together & forms pairs of rope like structures called chromatin pairs.

Question 16

What does it mean to maintain homeostasis?

Answer 16

Constantly changes structure to keep up with it’s changing environment.

Question 17

Why do cells split?

Answer 17

Cells have to reproduce when surface area can no longer support the much larger volume with nutrients and needs to remove wastes.

Question 18

When does metaphase begin?

Answer 18

When chromatid pairs line up along the center of the cell.

Question 19

In metaphase why do cells line up along the equator/center?

Answer 19

to make it possible for the chromatids to position themselves so they can migrate to the opposite poles of the cell.

Question 20

What does cyto mean?

Answer 20

The cell

Question 22

What is the S phase?

Answer 22

When genetic material makes copies of itself.

Question 23

What is anaphase?

Answer 23

Phase when chromatids actually migrate to the opposite poles of the cell.

Question 24

How does chromatid move to opposite sides of the cell?

Answer 24

It pairs/split (Kayro, Kinesis) spindle fibers come pulling toward the pole contact.

Question 25

What is Kinesis?

Answer 25

To move

Question 26

What is karyo?

Answer 26

Nucleus/center

Question 27

When does telophase begin?

Answer 27

When spindle fibers are gone and the nucleus reappears.

Question 28

In the end of anaphase, what reappears,

Answer 28

Nucleus

Question 29

In the end of anaphase, what disappears?

Answer 29

Spindle fibers

Question 30

How long does telophase continue?

Answer 30

Continues until the cell splits in 2 (cytokinesis)

Question 31

What results from telophase?

Answer 31

2 daughter cells in mitosis.

Question 32

What are cells like in the end of telophase?

Answer 32

They are smaller then the original cell and are also identical in number & type of chromosomes.

Question 33

If there is a lower concentration of water inside the cell what happens to the cell?

Answer 33

Turgid pressure increases.

Question 34

If there is a higher concentration of water inside the cell what happens to the cell?

Answer 34

Plasmolysis
