(WPF)

I'm sure this is not the first time I did this. I made photomicrographs of the cells of the apple skin and the fruit immediately within the flesh of the apple. The cells of the skin were stable and sharply formed. The cells within the fruit of the apple are fluid-filled and therefore less geometrical in shape. You can see some structures on the surface of the apple interior.
