Cell Division/Reproduction Study Guide 2015 Name__________________
1.
Compare and contrast the process of asexual cell division for prokaryotic and eukaryotic cells, to include the different names of each process. Sentences or a Venn diagram may be used.
2.
Compare and contrast asexual with sexual reproduction for eukaryotes, to include the names of each process and the chromosomal outcome. Sentences or a Venn diagram may be used.
3.
The table below describes cell processes, but scrambled as to order or timing. Provide a name for each of the processes shown, and list the timing from 1 to 7.

Name of process Description of process
The chromosomes separate and are pulled to opposite sides of the cell by the spindle fibers.
The chromosomes line up at the equator of the cell.
Normal operation of the cell, where DNA is not visible as the chromosomes instruct the cell what operations to conduct.
The chromosomes decondense, becoming invisible, and a nuclear membrane forms surrounding the area where the chromosomes had been.
DNA duplicates itself, chromosomes start to become visible, and other cell organelles are copied.
The nuclear membrane breaks apart. Chromosomes shorten and are now completely visible. Two pairs of centrioles move to opposite ends of the cell. Spindle fibers attach from them to the chromosomes.
The cytoplasm splits in two as the cell membrane (or cell wall also, for plant cells) pinches into two equal parts.

4.
Explain at least three reasons why an organism might need to use mitosis to create new cells.
Cite specific examples of the organism and tissue involved.
Need for new cells via mitosis
Reason Tissue Organism
5.
“Too much of a good thing” was a phrase appearing over 500 years ago in a play by William
Shakespeare. Apply that phrase to mitosis, to explain both how mitosis can be considered a “good thing” and how too much mitosis can be a very bad thing.
6.
During late interphase, ALL cell organelles, including chromosomes, are duplicated. Yet, the steps of mitosis focus MOST on what happens to the chromosomes. Explain why the chromosome duplication is of greatest importance, and why errors in duplication of chromosomes can cause severe problems.
