I wanted to see what a spinach leaf that was from inside the refrigerator was like and whether or not it would differ from a leaf outside (the structure of which I was already familiar with from past biology class microscope activities). I also wanted to use a more pigmented sample. The leaf seemed more browned under the microscope, perhaps due to the fridge making it cooler than what the plant is normally “accustomed to” and the fact that the leaf was already long separated from its plant. If you look closely I think those are either cell wall divisions or leaf veins that can be seen and there are what appear to be small holes in the leaf as well. #Bio60_2021

(no idea if my last post about this went through the first time so here it is again)
I didn’t feel like disposing of the petri dishes from the partner microbiome experiments from July 15 and wanted to (safely) see how the bacterial colonies would grow.
Sure enough, they grew significantly since then, with the colonies also attaining differing characteristics (texture, color, size) that were more prominent/noticeable than before.
I carefully took a sample from a particularly large, round brown colony from one of my household’s “July 15 pre-brush, post-dinner” petri dishes and observed a myriad of small brown bacteria. The cell bodies were hard to distinguish in detail, although a few can be seen.
