Name:
This test is to be completed on your own, the essay sections should not be the same as anyone else’s
(word for word) If that is what I find you both will receive 0 for this test.
Structure/Function
Cell Part
1) Stores material within the cell (General)
2) The sites of protein synthesis
3) Transports materials within the cell
4) Organelle that manages or controls all the cell functions in a
eukaryotic cell
5) Digests excess or worn-out cell parts, food particles and invading
viruses or bacteria
6) Small bumps located on portions of the endoplasmic reticulum
7) Provides temporary storage of food, enzymes and waste products
8) Produces a usable form of energy for the cell
9) Packages proteins for transport out of the cell
10) The membrane surrounding the cell
11) Name for the collection of DNA in the nucleus of eukaryotic cells
12) Consist of hollow tubes which provide support for the cell
13) Small hair-like structures used for movement or sensing things

Name:
20) What does the Cholera do directly to the intracellular processes (be specific)
21) The two circles next two fluid absorption and fluid secretion need either (+ or -) depending on
how you think the cholera effects fluid in the intestine
22) What is the most reasonable major symptom a patient with cholera would be suffering from and
ultimately what causes them to die. (use the diagram above to explain)
23) What happens to Blood glucose concentrations after the cholera has infected the cells and why?
