What are the three reasons that cells divide? 

Growth, repair, and reproduction 
100

How many cells are produced at the end of mitosis? 

2 identical cells 

100

What is crossing over and when does it occur? 

Crossing over is when two chromosomes switch genetic information and it occurs during prophase I. 

100

What is the name of the location where a spindle fiber attaches to a chromosome? 

Centromere 

100

True or false: The cells that result from meiosis are genetically identical to each other. 

False 

200

What are the three phases of the cell cycle? 

Interphase, mitosis, cytokinesis 
200

Which phase is shown in the photo below? 


Metaphase 

200

How many cells result from meiosis and how many chromosomes are in each cell? 

4 cells, 23 chromosomes in each cell 

200

Gametes have how many chromosomes? 

23 

200

What happens during interphase? 

The cell grows, the DNA duplicates, and the cell prepares for division 

300

How many chromosomes do body cells have? 

46 

300

During which phase of mitosis do the chromatid separate and get pulled to opposite sides of the cell? 

Anaphase 

300

Which phase is shown in the image? 


Anaphase II

300

What are homologous chromosomes? 

Chromosomes that have the same size, shape, and genetic information. 

300

Which phase of meiosis is shown in the image?

Prophase II 

400

Why is it important for the DNA to be copied during interphase? 

The daughter cells would not have the correct number of chromosomes if the DNA was not copied 

400

Which phase is shown in the photo below? 


Telophase 

400

Which phase of meiosis is shown in the image? 


Telophase I / Cytokinesis 

400

What is the difference between diploid cells and haploid cells? 

Diploid cells have two copies of each chromosome while haploid cells only have one copy of each chromosome. 

400

Which phase of meiosis is shown in the image?

Telophase II / Cytokinesis 

500

What is the longest phase of the cell cycle? 

Interphase 

500

During which phase of mitosis do chromosomes first become visible under a microscope? 

Prophase 

500

Which phase is shown in the following image? 


Metaphase I 

500

How are chromatids and chromosomes related to each other? 

Two chromatids make up a chromosome. 

500

How is metaphase in mitosis different from metaphase I in meiosis? 

In metaphase I of meiosis, the chromosomes are lined up next to their homologous pair, but they do not do this in mitosis.
