Bio A – Cell Division
Cell Division Study Guide:
Chromosomes:
1. DNA has two forms chromosomes and chromatin. Summarize each below including the
following:
a. How are they structurally different?
b. What is the advantage/disadvantage to each form?
c. When in the cell cycle does DNA take each form?
Cell Cycle: Describe what happens in each phase of the cell cycle
- Interphase:
- M phase:
- G0:
Mitosis: In your words SUMMARIZE the events of each phase in a single sentence. Focus
on the KEY events, not every little detail. Do not just copy a list of information from your
notes.
- Prophase
- Metaphase
- Anaphase
- Telophase
Bio A – Cell Division
Name each phase of mitosis:
What is cytokinesis? When does it occur?
-
Compare cytokinesis in plant and animals:
How do cells control when a cell divides? Provide specifics.
- What happens when this control is lost?
What is the different between benign and malignant tumors?
What does metastasize mean?
Meiosis
Provide TWO reasons why we need a different mechanism of cell division to make gametes
than we do for body cells:
What do the terms haploid and diploid mean? Provide examples of each type of cell.
Bio A – Cell Division
What happens in meiosis I that makes each reproductive cell unique? Describe this process or
draw a picture to show it.
Describe what the term independent assortment means:
Fill in the chart below to compare mitosis and meiosis:
Mitosis
Meiosis
Type of cells
How many divisions?
Haploid or diploid at
beginning?
Haploid or diploid at end?
Total number of cells at
end of cytokinesis?
Are cells same or
different at the end?
Reproduction:
Which type of reproduction produces identical offspring? ____________________
Which type of reproduction produces very different offspring?____________________
Human body cells have _______________ total chromosomes
_________ of them are the sex chromosomes
- Having 2 X chromosomes (XX) makes you __________________________.
- Having an X and a Y chromosome makes you _____________________.
The remaining 22 pairs are called ______________________.
Explain how fertilization restores the diploid number of a human cell:
What type of cell division follows fertilization?
