Answer the following questions:
  1. At what magnification was your onion cells image (40X, 100X, or 400X)? 100x
  2. At what magnification was your cheek cells image (40X, 100X, or 400X)? 100x
  3. How do the shapes and structures within the onion cells differ from that of the cheek cells? They are different shapes and sizes. Also, the onion cells looked almost like they were columns, but the cheek cells looked irregular and misshapen.
  4. Which cells seem to be arranged in a more regular pattern?
The onion cells seem to be arranged in a regular pattern, while the cheek cells appeared scattered, without a definite pattern.
5. What structures were you able to see in both type of cells?
We were able to see the nucleus and the cell membrane in both types of cells
6. What structures were you only able to see in the onion cells?
We were only able to see the cell wall in the onion cells, and not in the cheek cells.
7. One difference between plant and animal cells that we learned about is that plant cells contain chloroplasts. Were there many chloroplasts visible in the onion cell? Why do you think this is? (Hint, think of the function of chloroplasts and the part of the plant that an onion is)......
No, there were not many chloroplasts in the onion cell. We think this is because the main function of chloroplasts is to convert sunlight into energy for the cell. Since the onion bulb grows underground, it does not recieve sunlight and therefore, doesn't have chloroplasts.
