The Cell Cycle

Question 1

Which grows at a faster rate, surface area or volume? Why?

Answer 1

Volume increases faster because it is 3-Dimensional and surface area is only 2-Dimensional

Question 2

This problem occurs when a cell grows too large for the fixed amount of DNA that controls its activities.

Answer 2

DNA Overload

Question 3

This problem happens to cells that become too big because the ratio of surface area to volume becomes too small.

Answer 3

Transportation Issues

Question 4

The process occurs before a cell grows too large.

Answer 4

Cell Division

Question 5

2 of these are produced when 1 cell divides.

Answer 5

Daughter Cells

Question 6

These are the 3 steps of the cell cycle.

Answer 6

Interphase, Mitosis and Cytokinesis

Question 7

These are the TWO steps in cell division.

Answer 7

Mitosis and Cytokinesis

Question 8

These are the 3 parts of Interphase, in order.

Answer 8

G1, S Phase, and G2

Question 9

This is the division of just the nucleus.

Answer 9

Mitosis

Question 10

These are made of DNA and carry genetic information.

Answer 10

Chromosomes

Question 11

This is what a “replicated” chromosome is composed of.

Answer 11

TWO sister chromatids

Question 12

This is the connection point where 2 sister chromatids are connected.

Answer 12

Centromere

Question 13

This is a period of growth, replication and activity that happens between cell divisions.

Answer 13

Interphase

Question 14

The cell grows larger during this first part of interphase. New proteins and organelles are also produced.

Answer 14

G1

Question 15

DNA replication and synthesis of new chromosomes occur in this part of interphase.

Answer 15

S Phase

Question 16

The cell prepares for cell division by producing organelles like centrioles.

Answer 16

G2

Question 17

These are the 4 phases of mitosis in order

Answer 17

Prophase Metaphase Anaphase Telophase (P-M-A-T)

Question 18

These are the events of Prophase

Answer 18

1. The nucleus dissolves & replicated chromosomes become visible. 2. Centrioles start to move to opposite sides. 3. Spindle fibers start to form

Question 19

This is what happens in Metaphase

Answer 19

Replicated chromosomes line up in the Middle of the cell between centrioles. Each is connected to a spindle fiber.

Question 20

This is what happens in Anaphase

Answer 20

Sister chromatids of replicated chromosomes are pulled Apart

Question 21

This is what happens in Telophase

Answer 21

Two nuclei form around opposite groups of chromatids in a single cell. Cytokinesis also begins here.

Question 22

This is how many nuclei are present in one cell when MITOSIS is complete.

Answer 22

Two

Question 23

These are the only 2 phases of mitosis where replicated chromosomes are seen.

Answer 23

Prophase and Metaphase

Question 24

This is the job of spindle fibers

Answer 24

To organize chromosomes and pull sister chromatids apart

Question 25

This process occurs after mitosis and causes the rest of the cell to divide.

Answer 25

Cytokinesis

Question 26

These type of cells carry out cytokinesis by “pinching in” (forming cleavage furrows) until they divide.

Answer 26

Animal Cells

Question 27

Because a plant cell has this, it cannot pinch in during cytokinesis.

Answer 27

Cell Wall

Question 28

This forms between 2 plant cells when they undergo cytokinesis.

Answer 28

Cell Plate

Question 29

If a parent cell has 46 chromosomes, how many chromosomes will be found in each of the daughter cells after cytokinesis is complete?

Answer 29

46

Question 30

This is the formula for calculating volume.

Answer 30

L x W x H

Question 31

This is the unit in which volume is measured.

Answer 31

cm3

Question 32

This is the formula for calculating the surface area of a cube.

Answer 32

6 (L x W)

Question 33

This is the unit in which surface area is measured.

Answer 33

cm2

Question 34

During which phase of mitosis do chromosomes become visible?

Answer 34

Prophase

Question 35

What kind of cells undergo the cell cycle?

Answer 35

Somatic (body) cells undergo the cell cycle.
