Principles of Biology : Quiz 10 Study Guide


We will take Quiz 10 on Wednesday, October 29. I recommend that you answer these questions yourself or with classmates. This not a graded assignment, nothing is to be turned in. These questions are just to help you prepare for this quiz.
Reading: You should read Chapter 8, up to page 160 (up to section 8.7) and Chapter 10 up to Section 10.7 (page 197). Notice, we are skipping chapter 9.
Also, you should be familiar with the photosynthesis handout.
And the mitosis power point slide show from lab (Wed. 10/22).

There are flashcards and animations on the Aris site you should study.   Quick Link to the Aris Site.

Questions to consider:

Photosynthesis
1) What is general equation of all photosynthetic systems, bacterial or eukaryotic, whether they oxidize water or hydrogen sulfide?
2) What is "cyclic photophosphorylation?" In whom does it occur? What does it produce? What does it not produce that is needed for the fixation of carbon?
3) What is "non-cyclic photophosphorylation?" In whom does it occur? What does it produce?
4) Explain the light dependent reactions of photosynthesis. What two photosystems are involved? How are they the same, how are they different?
5) What happens in the light independent reactions of photosynthesis? What are the reactants? What are the products?
6) What is the Calvin cycle? What is cycling? What is happening in one crank of the cycle? Theoretically, in six cranks?
7) What is "photooxidation?" How have plants responded to the problem? (this will be discussed briefly at the beginning of class, Monday).

Cell Division - Mitosis
8) What is "mitosis?"
9) What is the cell cycle? What are the stages in the cell cycle?
10) What are the three subdivisions of Interphase? What is happenning during each of these subdivisions?
11) What are the four stages of meiosis (studied in lab, or the five from the text) and what is happenning at each stage?
12) What is diploidy? haploidy?
13) What is the human karyotype? How many chromosomes are present?
14) What is a "chromasome?"
15) What is a "chromatid?"
16) What are centromeres?
17) What are centrioles?
18) What are histones? nucleosomes?
19) What is chromatin?
