7 Eukaryotic Cell Structure 
Background
Cells come in all different sizes and shapes. They are classified into two major groups based on structure. Prokaryotic cells are much smaller and do not contain any membrane-bound organelle. Eukaryotic cells are larger and contain numerous membrane-bound organelles. Prokaryotic cells will be examined in the laboratory exercise that will survey the diversity of life on earth. This laboratory exercise will focus on the structure of the two most common types of eukaryotic cells: plant and animal cells.
To appreciate the cell in action, watch The Inner Life of the Cellby BioVisions at Harvard University (3 min 12 sec). This video  shows movement of organelles and substances inside your cells in real time.
Purpose
Prepare wet mounts of plant and animal cells for microscope observation.
Use the light microscope to compare and contrast the structure of plant vs. animal cells.
Materials (demonstrated in video)
Microscope
Microscope slides  and cover slips
Toothpick
Water (or 0.9% sodium chloride solution)
Medicine dropper
Methylene blue (or iodine) stain
Elodea plant
Cheek cells
Online: Virtual microscope with plant slide
Procedure for plant cell

how to prepare a wet mount https://youtu.be/UWbGZMO4o_U(2 min 30 sec) 
To create a wet mount of an Elodea leaf, this general procedure was followed.
Put a drop of water on the center of a slide.
Cut an extremely small piece of an Elodea leaf and place it on the water.
Place a coverslip onto the slide.
Observe the plant cell slide under the virtual microscope by following this procedure.
Go to the virtual microscope.
Click Launch and then Explore
Click the “?” in the microscope slide box
In the slide catalogue, select “Plant Slides”.
Inside, select “Plant Cells.” The virtual microscope loads the Plant cell slide at the center of the stage. You will see a blurry green field of view.
Click “10X” (low power objective lens). Watch as the nosepiece moves until the low power objective lens clicks in. Use your mouse to adjust the Coarse Focusuntil the image is in focus. Fine tune it using the Fine Focus. Slowly slide the Light Adjust to the right to obtain optimum brightness. Click on the field of view to move the plant side. Draw the image of plant cells in the field of view for low power.
Click “40X” (high power objective lens). This time, only adjust the Fine Focus & Light Adjust to obtain the clearest image with optimum light. Moving the Coarse Focus will endanger the lens & slide and make you lose your focus. 
Draw the image in the field of view for high power.
Drawing of plant cells: label cell and observed organelles.  
Procedure for animal cell 
View Cheek Epithelial Cells (3 min 52 sec) to observe how to prepare a wet mount of human cheek cell and view images of the cheek cells under low & high power magnification.
To create a wet mount of cheek cells, this general procedure was followed.
Put a drop of methylene blue on a slide. Caution: methylene blue stains clothes and skin.
Gently scrape the inside of your cheek with the flat side of a toothpick.
Stir the end of the toothpick in the stain and then throw the toothpick away.
Place a coverslip onto the slide by lowering it at a 45 degree angle to prevent formation of air bubbles.
Draw the cheek cell images under low & high power magnification as seen in the video.
Discussion/Conclusion 
Stains may be used but not all organelles are seen, why?
Describe the shape of the plant cell. List the organelles that were visible.
Describe the shape of the human cell. What organelles of the cell were visible?
Describe visible similarities and differences between plant and animal cells.
What observations support the claim that plant and animal cells are eukaryotic?

The scope of public health services is enormous, encompassing such services as food and drug safety, disease surveillance, emergency response, disease prevention, and health education and promotion. For this Assignment, you will select and research one of the key federal public health agencies discussed throughout Units 6, 7, and 8. Then you will answer some important questions about the agency you have selected in a well-developed research paper.
Unit outcomes addressed in this Assignment:
Identify the role that the FDA has in monitoring food safety.
Describe the role of the FDA in the marketing of drugs and postmarket monitoring.
Discuss how the FDA works with other public health agencies in improving health outcomes.
Course outcome(s) assessed in this Assignment:
PU120-4: Describe how public health agencies work together on local, state, federal and global levels to improve health outcomes.
GEL-1.02: Demonstrate college-level communication through the composition of original materials in Standard English.
Instructions
Most people have heard of the CDC and the FDA, but very few can explain everything these agencies do on a daily basis to keep Americans healthy and safe. Moreover, many Americans have never heard of the other key federal public health agencies, such as the NIH and HRSA, that play a major role in in the public health system today.
The scope of public health services is enormous, encompassing such services as food and drug safety, disease surveillance, emergency response, disease prevention, and health education and promotion to name a few. 
For this written Assignment, you will select one of the key federal public health agencies that were discussed throughout Unit 7 (see Table 12-2: “Key Federal Health Agencies of the Department of Health and Human Services” in the course textbook for a brief overview of each of these health agencies), including:
Agency for Healthcare Research and Quality. Retrieved from http://www.ahrq.gov/
Centers for Disease Control and Prevention. Retrieved from http://www.cdc.gov/
Food and Drug Administration. Retrieved from http://www.fda.gov/
Health Resources and Services Administration. Retrieved from http://www.hrsa.gov/index.html
Indian Health Services. Retrieved from http://www.ihs.gov/
National Institutes of Health. Retrieved from http://www.nih.gov/
Substance Abuse and Mental Health Services Administration. Retrieved from http://www.samhsa.gov/
After providing a brief overview of the public health agency you have selected, you will research one specific public health service that the federal public health agency provides and write a critical analysis essay that explains the following:
A description of the service you chose (for example, the FDA completes food inspection of imported foods);
A list of the steps or protocols used to carry out the chosen service;
A description of the core function(s) of public health, mandated by the IOM, under which this service falls;
An explanation of which of the 10 essential public health services this program fulfills;
A discussion of how this service achieves the desired health outcomes; and
A discussion of the collaboration efforts with local, state and if applicable, global health organizations.
Proposed Outline of Unit 8 Written Assignment
