This is a picture and drawing of a Fern Rhizome. This is under the 140X magnification.
We can observe a very distinct layered structure. The inside consisted of loosely packed cells which were surrounded by a black filament. As we go outwards, the cells become more compactly packed while the cells become smaller.
The third layer has larger cells, however they are also very compactly packed. They are mostly rectangular in shape. The last two layers have smaller and very densely packed structures.
A blue tint has been added to this Fern Rhizome so that the cells and components in the cells are better and more clearly visible.

This is a picture and drawing of an onion peel under a 340X magnification.
We can see the cells of the onion are really rectangular and compactly packed. It looks somewhat like a brick wall. Upon closer inspection, we can see various irregularities present within such as varying cell sizes and shapes, development of bacteria etc.
The image with the dark irregular figure is the depiction of a bacterium in the onion. Around the cells and within it, we can see various particles such as nuclei, vacuoles, nutrients etc.

Overall, the class today really showcased a different aspect of biology, which is very different from what I am used to studying. Looking into the various constituents of a cell through hands-on experience has definitely improved my experience and perspective about the subject.
