A First Look at Cells Team Name:

Team Members (first names only) Andrew, Gillian, Micheal, Nicole


 * Slide Number: 1**


 * Slide Image (High Power)**


 * Use High Power Magnification to estimate the size of the cells in your specimen (show your work):**
 * We think each cell is about 4 um. The image took up the entire field of view, which is, in high power, 400 um. We estimated that there were about 100 cells in the field of view. 400 um/100= 4 um.**


 * Description (write a complete description – refer to questions #1 -#6 for the types of details your description should include. Be sure to state which cell type you think is on this slide):**
 * The objects are rectangular in shape, but they have rounded edges. We think the objects are cells. All of the cells are relatively the same size, though some are slightly larger or smaller than others. The arrangement seems random. Inside the larger shapes which we think are cells, there is a large, dark circle. We think these may be nuclei. We think this is the onion root tip. There is a cell wall, so it is a plant cell. The cell is not green, so it does not have chloroplasts like an onion leaf does. The only remaining option is an onion root tip.**

__Second Slide__

 * Slide Number: 2**


 * Slide Image (High Power)**


 * Use High Power Magnification to estimate the size of the cells in your specimen (show your work):**
 * We think each cell is about 1 um. The image took up the entire field of view, which is, in high power, 400 um. We estimated that there could be about 400 cells in the field of view. 400 um/400= 1 um.**


 * Description (write a complete description – refer to questions #1 -#6 for the types of details your description should include. Be sure to state which cell type you think is on this slide):**
 * The objects are random in shape, and they don't all look similar. The cells are not all the same size; some are much bigger than others.. The arrangement seems random. We think this is bacteria, because it looks like it does not have a nucleus.**

__Third Slide__

 * Slide Number: 3**


 * Slide Image (High Power)**


 * Use High Power Magnification to estimate the size of the cells in your specimen (show your work):**
 * We think each cell is about 8 um. The image took up the entire field of view, which is, in high power, 400 um. We estimated that there were about 50 cells in the field of view. 400 um/50= 8 um.**


 * Description (write a complete description – refer to questions #1 -#6 for the types of details your description should include. Be sure to state which cell type you think is on this slide):**
 * The objects are hexagonal and pentagonal in shape. We think the objects are cells. All of the cells are relatively the same size, though some are slightly larger or smaller than others. The arrangement does not seem random. Inside the larger shapes which we think are cells, there is a large, dark circle. We think these may be nuclei. We think this is the frog skin. It looks like the texture of frog skin.**

__Fourth Slide__

 * Slide Number: 4**


 * Slide Image (High Power)**


 * Use High Power Magnification to estimate the size of the cells in your specimen (show your work):**
 * We think each cell is about 25 um. The image took up the entire field of view, which is, in high power, 400 um. We estimated that there were about 16 cells in the field of view. 400 um/16= 25 um.**

The cells shown on the slide above are ovular in shape, and have a blueish greenish tint. The reason we think they might be cells is because of the dark circles located within the figures which we believe to be Nuclei. The arrangement could be looked at as random, but with high-power it looks like a brick wall. They also all have rounded edges, and most of them have fairly the same size. We believe that this is the onion leaf because it has a greenish tint which could be chlorophyll which only plant cells have. We know slide 1 is the onion root tip, and the onion leaf is the only other plant cell.

__Fifth Slide__

 * Slide Number: 5**


 * Slide Image (High Power)**


 * Use High Power Magnification to estimate the size of the cells in your specimen (show your work):**
 * We think each cell is about 20 um. The image took up the entire field of view, which is, in high power, 400 um. We estimated that there could be about 20 cells in the field of view. 400 um/20= 20 um.**


 * Description (write a complete description – refer to questions #1 -#6 for the types of details your description should include. Be sure to state which cell type you think is on this slide):**
 * The string like object on the screen has dull colors, or basically no colors at all. It seems to twist, and is obviously very thin. We believe it is the human cheek smear. It does not appear to have a cell wall. Also, the cheek smear was the only option left because we identified all of the other options.**
