Question 22

How many stages are there of cell division?

Answer 22

3

Question 23

What are the three stages of cell division.

Answer 23

Interphase, Mitosis, Cytokinesis

Question 24

How many phases does Mitosis have?

Answer 24

4

Question 25

What are the four stages of Mitosis

Answer 25

Mitosis Prophase, Mitosis Metaphase, Mitosis Anaphase, Mitosis Telophase.

Question 26

What happens during Interphase.

Answer 26

The cell grows and prepares to divide. The DNA is copied/replicate/duplicated.

Question 27

What stage is the longest stage in cell division?

Answer 27

Interphase - Stage 1

Question 28

What stage produces two new daughter cells?

Answer 28

Cytokinesis - Stage 3

Question 29

What happens in telophase?

Answer 29

TWO NEW NUCLEi are created and the cell begins to divide.

Question 30

What happens in Anaphase?

Answer 30

Spindle fibers attach to the centromeres and the chromosomes PULL APART to opposites sides of the cell.

Question 31

What happens in Prophase?

Answer 31

Nuclear membrane disappears and the Chromotids PAIR UP.

Question 32

What happens in Metaphase?

Answer 32

Chromosomes line up in the MIDDLE of the cell.

Question 33

Why would cells divide?

Answer 33

For repair, replacement and growth.

Question 34

What is meiosis?

Answer 34

When sex cells (egg and sperm) divide.

Question 35

What type of cells divide during Mitosis?

Answer 35

All body cells (not sex cells).

Question 36

What is the female sex cell.

Answer 36

Egg - X

Question 37

What is the male sex cell?

Answer 37

Sperm - can be X or Y

Question 38

During what stage does DNA make a copy of itself?

Answer 38

Interphase - Stage 1.

Question 39

What is the difference between Mitosis and Meiosis?

Answer 39

Mitosis divides body cells. Meiosis divides sex cells.
