18
Q

What is G1

A

Interphase, the cell grows, replicates, and does metabolic activities

19
Q

What happens during S?

A

Our DNA is copied

20
Q

What happens during G2

A

Final preparations

21
Q

What happens at M

A

The division of the cell

22
Q

What 5 phases are in M

A

Prophase Metaphase, Anaphase, telophase and cytokinesis

23
Q

What happens in prophase

A

The chromatids line up along the equator and the centromere splits giving two separate identical chromosomes

24
Q

What is a chromatid

A

Two chromosomes

25
Q

What is a centromere

A

Its what the connects the two chromasomes

26
Q

What are the first three things that happen in the prophase

A

The centrioles migrate to the poles to form spindles and asters, the niclear membrane starts to break down and is totally gone at the end of the phase, and chromatids shorten and thicken and become visible

27
Q

What other three things occur in the prophase

A

The chromatids attach to spindle fivers by their centromeres, the nucleolus disappears,and chromatids begin to move to the equator

28
Q

What happens in the anaphase?

A

Sister chromosomes are pulled to opposite end of the cell, spindle fibers aid this movement

29
Q

What else happens in anaphase

A

Cytokinesis begins

30
Q

What is cytokinesis?

A

The splitting of the cytoplasm

31
Q

When does telophase begin?

A

When the chromosomes reach opposite poles

32
Q

What happens in telophase

A

The asters and spindles disappear,a new nuclear membrane forms around each daughter cell, the nucleolus reappears, and the chromosomes revert back to chromatin

33
Q

What happens in a plant cell when there is cytokinesis

A

A cell plate begins to form in the middle of the cell instead of the cell membrane pinching

34
Q

What do plants not have that is necessary for animals to have

A

Centrioles

35
Q

How is telophase of mitosis the reversal of propahse

A

In prophase chromatids are together and in telophase they are separated

36
Q

Where in the cell does most of the activity occur during mitosis

A

In the nucleus

37
Q

What are the advantages of asexual reproduction

A

Quick, efficient results, and more offspring

38
Q

What is the purpose of mitosis

A

To get two cells exactly alike

39
Q

Why do we go through mitosis?

A

To repair, grow, and everyday maintenance

40
Q

What part of the cell division process is mitosis?

A

M

41
Q

What is a hood way to remember the order of phases

A

PMAT

42
Q

What is a good what to remember the order of the cycle

A

GSGM

43
Q

What does somatic mean

A

Body cell
