Answer 18

False

Question 19

The cell that divides is called the

Answer 19

parent cell

Question 20

The new cells are called

Answer 20

daughter cells

Question 21

Presence of 2 complete sets of chromosomes in an organism’s cell, each parent contributing a chromosome to each pair

Answer 21

diploid (2n)

Question 22

Presence of a single set of chromosomes in organism’s cells
duplicates the centrosome

Answer 22

haploid (n)

Question 23

Assembles the microtubules that make up the spindle fibers

Answer 23

Mitotic spindle

Question 24

Mitosis is a form of ________ reproduction

Answer 24

asexual

Question 25

Mitosis creates _______ _______ ___

Answer 25

two daughter cells

Question 26

The daughter cells in mitosis are _______

Answer 26

identical

Question 27

What are the purposes of mitosis

Answer 27

Growth
Repair
Replace

Question 28

Centrosomes outside nucleus duplicate and move away from eachother
Spindle fibers appear between seperating centrosomes
nuclear envelope begins to fragment
nucleolus disappears as chromosomes condense

Answer 28

prophase

Question 29

Each chromatid attached to spindle fiber and some spindle fibers stretch from each spindle pole and overlap

Answer 29

prometaphase

Question 30

Centromeres align at equator
spindle fibers attached to sister chromatids come from opposite spindle poles

Answer 30

metaphase

Question 31

sister chromatids part and becomes daughter chromosomes that move toward spindle poles. Each receive same number and kinds of chromosomes as parental cell.

Answer 31

Anaphase

Question 32

Last step of mitosis
daughter cells are forming
nuclear envelopes reappear
nucleoli reappear
chromosomes will become indistict chromatin

Answer 32

Telophase

Question 33

Division of cytoplasm
cleavage furrow (slight indentation) passes around circumference of cell
Actin filaments form a contractile ring
As ring becomes smaller, cleavage furrow pinches cell in half
Cell becomes enclosed by its own plasma membrane

Answer 33

Cytokinesis
