Observing tomato peels and tomato's flesh through the foldscope at 50x, 140x and 340x.
Preparing the slide: For tomato peels, I simply took a piece of tomato peel (around 0.3cmx0.5cm, it was right-angled triangle shape somehow). Then, I used tweezers and my fingers to press it against the slide and then applied cello-tape on it. Making peels of tomato flesh was slightly harder. I rubbed the piece with some pressure (gently) against the central area of the slide which left some deposits of it cells. Then, I applied cello-tape on it.
Difficulties: My first sample of the flesh dried very quickly and I had to remake the sample. In this sampling technique, sometimes it happens to me that there are no cells on the slide, or very little (not enough to observe properly).

Observations: On the tomato peel at 50x, I observed some area near the edge of the sample. The focus is a little-off but still some cells are visible. On the tomato peel at 140x, the cell boundaries and the grid like arrangement can be seen much more clearly. On the tomato peel at 340x, individual cells can be seen. The cells appear to be greener in color as compared to the previous samples. On the tomato flesh at 50x, a large mesh-like structure can be seen, however, it is not clear enough to understand the cells. On the tomato flesh at 140x, it is much more clearer and some red areas can be distinguished from the white-colored areas. On 340x, we can see some cells properly and the large two black-boundary structures can be seen. I am not entirely sure what they are because this could be air bubble or water or maybe something related to the flesg.
