On the second day, we used the foldscope to examine two parts of a potato: the outer skin and the inner flesh. Although they came from the same vegetable, their microscopic structures appeared surprisingly different.

Preparing the potato skin required careful peeling. Under the foldscope, the skin consisted of densely packed cells with noticeable variations in shape and colour. As the magnification increased, the cell walls became more distinct, and some regions appeared darker than others, likely due to overlapping layers of tissue.

The potato flesh presented a contrasting view. The cells appeared lighter, rounder, and more loosely arranged. At higher magnifications, differences in cell size became more apparent, and some cells contained darker internal structures that were easier to observe. Compared to the skin, the flesh seemed less compact and more irregular in its organisation.

As for the tomato, we examined its skin and flesh. What stood out immediately was the colour. Unlike the previous samples, which were mostly pale or brownish, the tomato displayed a vibrant orange-red pigmentation that made the microscopic view much more striking.
The tomato skin consisted of small, tightly packed cells arranged in dense clusters. As magnification increased, the individual cell shapes became clearer, revealing an irregular but organised pattern.

The pigmentation was not distributed uniformly, with some cells appearing darker than others. The overall structure gave the tissue a compact and protective appearance.

In contrast, the tomato flesh showed a much looser cellular arrangement. The cells were larger, more rounded, and separated by noticeable spaces. Their translucent nature made it possible to observe faint internal structures within some cells. Compared to the skin, the flesh appeared less rigid and more suited to storage and support.
Comparing the two tissues highlighted how different parts of the same fruit can possess distinct microscopic characteristics. The skin's compact structure contrasted sharply with the openness of the flesh, demonstrating how cellular organisation reflects the specific role each tissue plays within the tomato.
