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.
I picked, dried, and dusted a slide with yellow pollen from a flower on campus. I collected the sample from a decorative flowering bush on Stanford campus, California near Wilber dining. I was particularly interested in how the pollen would appear under magnification and if I could see individual pollen granules. I peeled back the…
I picked, dried, magnified and photographed a cape honeysuckle. I collected the sample from a decorative plant near EVGRA on Stanford campus, California. This flower was interesting to me of its bright orange color. I wanted to see what the cells of such a distinctively colored flower would look like and I also wanted to find out if the petal was translucent enough to be magnified. I isolated a few petals and pressed them in the spine of a book for twelve days. Then I selected one petal, placed it between two slides and secured the slides with scotch tape. I then placed the slide in my foldscope, positioned the foldscope above a light source, and adjusted my focus until the image was clear. This was the resulting image. This post is for a Bio60_2021 class assignment.

While studying outside at Encina Commons, a small fly kept hovering over my computer so I decided to catch it and take a look at my first animal organism under the microscope. I was careful not to crush it too much, and laid it out flat on the glass side with its back and wings…
I have a bunch of gummy bear wrappers in my dorm trash, and was curious to see what the plastic wrapper would look like up close. I cut a small piece with scissors to examine. #Bio60_2021
Bananas are my favorite snack, so I examined a banana peel fiber from yesterday’s snack in my dorm. I ripped off a small piece that was dangling off the peel, and noticed it was browning a bit compared to yesterday. At first, the piece I examined was a bit thick, so even with bright light…
I decided to sacrifice and dissect a Passion flower from my backyard. Using a diagram from the web I’m pretty sure I viewed the petal corona fiber ( purple) ovary ( seeds?) stigma and anther ( both had green pollen grains) and the red petal ( awesome pigment granules!) #Bio60_2021
I was collecting flowers for some foldscoping but noticed they were home to some tiny hopping bugs. Managed to trap one and smash it on a slide ( had to) so I could take a look. Very cool! What is it? #Bio60_2021
