Today in class we worked on Onions cells. Then once you had finished finding the cells you had to answer two questions for grass cells, and one question for onion, and then you had to make a graph based on the animal, and the plant cell. In my group i had so much trouble trying to find cell, when Mr. Finley came over he told to make sure that the measurment for the hieght was as high as your pinkie finger. When we did that we noticed that it was so much better t0 see the cells. As the process for the clips with the onions, you have to have a very small sliced piece of the onion, and then you had to put one small drop of iodine, and then we put it under the microscope, and explored looking for cells.

  1. I didn't see that picture when I was looking through the microscope. Did my group do it wrong?

  2. My onion cell didn't look like that either, but I think that is because in that cell picture it dosn't look like they used iodine.
    Also, we didn't make a graph, we made a table, venn diagram, or something else to compare plant and animal cells.

  3. I agree the cell didn't look like that. It looked like a alligator's skin close up, to me, under the microscope.
