Q

What happens in synthesis?

A

DNA is copied in replication. Producing a copy of each chromosome. This is so each daughter cell has the right number of chromosomes

Q

What happens in growth two?

A

The cell division continues.

17
Q

What stage is where the cell spends the most time?

A

Interphase

18
Q

Describe prophase

A

Two centrioles move to opposite poles of the cell and send out spindle microtubles, forming the spindle
DNA condenses into chromosomes
Nuclear membrane dissolves

19
Q

Describe metaphase

A

The spindle attaches to the centromere of the chromosomes

Chromosomes line up on the equator

20
Q

Describe anaphase

A

Centromere divides and sister chromatids are pulled apart towards opposite ends of the cell by the contracting spindle
Each chromatid is now considered a chromosome

21
Q

Describe telophase

A

Chromosomes uncoil into stringy DNA
Spindle breaks down
Nuclear membrane reforms
Cytokinesis occurs

22
Q

Describe cytokinesis

A

The moment when the cell divides into two daughter cells

23
Q

Define: genetically identical

A

Having the exact same chromosomes

24
Q

Explain how mitosis produces 2 genetically identical nuclei

A

Stringy DNA coils up. Proceeds into IPMAT

25
Q

Why do cells divide?

A

To reduce SA:Vol ratio

26
Q

Where does mitosis frequently occur?

A

In developing embryos

27
Q

What are new cells needed for?

A

Damaged or infected cells

28
Q

How is cell division also used in asexual reproduction

A

Specially through mitosis

It’s essentially self replication

29
Q

What needs to be done in order for an organism to grow larger?

A

It needs to produce more cells. Each cell needs a copy of the organism’s DNA

30
Q

What are gametes?

A

Sex cells. Egg and sperm

31
Q

What ARE gametes? What do they do?

A

Gametes are haploid. They have a half set, as try pair up with the other half it will fertilize

32
Q

What is a somatic?

A

A body cell of two set of chromosomes. One from mom and one from dad

33
Q

Why does it mean to be a diploid?

A

The cell has a two pair chromosome set

34
Q

Before the cell splits, what is the cell for a brief moment?

A

Polyploid-4n

35
Q

How many pairs of chromosomes do humans have? What is the diploid number?

A

23 pairs

> diploid # (2n) =46

36
Q

What does it mean when a tumor recruits blood vessels and grow larger?

A

Angiogenesis

37
Q

What does is mean when a part of the tumor invades the blood vessel, and travels in another part of body?

A

Metastasis

38
Q

What’s the one way for tumors to grow?

A

By having blood vessels carry nutrients to the tumor

39
Q

Describe plant cell divison

A

Cellulose that comes from the Golgi apparatus makes a wall and the pectin spreads the wall apart from each other
