    In botany lab, I used a razor blade to scrape some of the stuff from the inner part of a red potato tuber and looked at it under the microscope, without any kind of stain. I didn't see anything resembling cells, but I saw a lot of little things that looked like air bubbles, sort of like in this pic, but just clustered together randomly rather than being in cells like in the picture. Are these starch grains or leucoplasts? Why wouldn't I have seen any cell walls? Are they destroyed by scraping with a razor blade? Or are there no cells in the inner part of a tuber?

    Yes. Here is a bit clearer image that has been stained.
