As part of the Exploring the Microcosm class at the Lodha Genius Programme, I had the exciting opportunity to examine a fern rhizome using a Foldscope 2.0! Although I was already aware that microscopes allow us to view structures that are invisible to the naked eye, using a Foldscope myself made the experience much more engaging and meaningful.
Using the foldscope was very simple, but it did take me some time to get used to it. In my opinion, the most fascinating fact about the Foldscope is the fact that it is made of paper.
The foldscope had 3 magnifications 50x,140x,340x And it was extremely cool that we could see each and every cell/structure of each microorganism. I found it very fascinating!!
50x At 50× magnification, the overall structure of the fern rhizome could be observed. A distinct circular vascular bundle was visible near the center of the field of view, surrounded by a large region of ground tissue composed of many closely packed cells. The stained slide showed different colors, with a dark reddish central region surrounded by greenish-blue rings. Although the individual structures were not very clear.
At 140× magnification, I could see much more detail than at 50×, the vascular bundle became much clearer. The outer region was made up of many closely packed, polygon-shaped cells. Around the centre. I could no longer see the entire cross-section. Cell boundaries were now clearly visible, allowing me to distinguish individual cells and observe differences in their size and arrangement.
At 340× magnification, the finest details could be seen. Individual cells became much clearer, and their outlines were easier to distinguish. I observed several large oval and circular structures grouped together near the center, surrounded by smaller tightly packed cells. The ring around the center appeared thicker and more detailed than it did at lower magnifications. At this magnification, I appreciate how complex the internal structure of the fern rhizome was and how many different-sized structures were packed into a very small space.
