Name: ____________________________________ Microscopes To complete this activity, you will be using a virtual microscope. You can access the virtual microscope at: http://www.udel.edu/biology/ketcham/microscope/ First, you should view the seven minute instructional video (click on the highlighted link). Test your skills using the virtual microscope by clicking on the highlighted link. View the tour in the “Getting Started” box on the right hand side of the page. View each of the four slides (“e”, onion root tip, bacterial capsule, cheek cell) at each level of magnification and sketch what you see. “e” 4X 10X 40X 100X 1. Why is it necessary to look at this slide under the microscope? Onion Root Tip Cell 4X 10X 40X 100X 1. Is this a prokaryotic or eukaryotic cell? 2. Is this a plant or an animal cell? How do you know? 3. Name three organelles found in both plant cells and animal cells. 4. Name two organelles found only in plant cells. 5. Why are no chloroplasts found in this cell (think about where onions are found)? Name: ____________________________________ Bacterial Capsule 4X 10X 40X 100X 1. Is this a prokaryotic or eukaryotic cell? How do you know? 2. Name one organelle found in all cells. 3. What is unique about the DNA in a prokaryotic cell? Cheek Cell 4X 10X 40X 100X 1. Is this a prokaryotic or eukaryotic cell? 2. Is this a plant or an animal cell? How do you know? 3. The microscope used in this lab isn’t powerful enough to view every organelle. Which organelles can you see? 4. Name two organelles that are not visible, but should be present in this cell.
