Q

In mitosis, what happens during anaphase?

A

Spindle fibers pull the chromosomes apart and into the new cell

16
Q

In mitosis, what happens during telophase?

A

Cytokinesis occurs (actual splitting of the cell)

17
Q

What is meiosis?

A

The development of sex cells

18
Q

What is a gamete?

A

A sex cell

19
Q

What is a female gamete?

A

The ovum

20
Q

What is a male gamete?

A

The sperm cell

21
Q

Meiosis produces what kind of cell?

A

Haploid cell

22
Q

T/F: Mitosis is more complex than Meiosis

A

False

23
Q

T/F: meiosis essentially goes through the same steps for cell division as mitosis.

A

True

24
Q

Which phase does mitosis go through that meiosis does NOT?

A

Interphase

25
Q

What are the steps in reduction division for meiosis?

A

Prophase I, Metaphase I, Anaphase I, and Telophase I

26
Q

What are the steps to equatorial division in meiosis?

A

Prophase II, Metaphase II, Anaphase II, and Telophase II

27
Q

What is the difference between metaphase in Mitosis and metaphase I in Meiosis?

A

There isn’t one

28
Q

What is the difference between division in mitosis and meiosis?

A

Meiosis splits into 4,

Mitosis splits into 2

29
