La observación de hoy es la planta que encontramos en la calle y se nos pega en la ropa. Algunos la conocen como cadillo. Coloqué un mozote seco y delgado en el portaobjetos. Logré ver unas líneas de color verde y oscuras. Se lograron ver algunas manchas de color naranja. Tomé un mozote grueso. La…

Epithelial cells

All our body is covered by epithelial cells like these, which were tyed with methylene blue. P.S. I’ve just seen this and I was so excited I couldn’t wait to updload the pictures.


La observación de hoy fue el hongo que le encontré a un planta. Le noté a la planta unos pelos delgados de color blanco. Con un poco de cinta los tomé con cuidado y lo coloqué al portaobjetos. El resultado fueron unas líneas con unas bolitas grises.


I found these little guys when I was observing the water of a flower vase and I thought it was so intereseting they could be there. Actually, you can found protozoans in almost any drop of water. Both organisms are of the group ciliophora and one of them belongs to the genus Vorticella.


I thought this little guy was a rotifer when I first saw it, but it was very small to be one. Then I started thinking that it could be a protozooan of the gender Vorticella and that made more sense. These organisms live in fresh water and have cilia to get their food; they also…


The word “trichome” comes from the greek and it means “hair” and actually trichomes are little hairs you can see on many plants, you must have seen them at least once. These can help the plant to protect itself against other organisms or the prevent water loss.

Wing scales of butterflies

Once I read on Facebook that the wings of butterflies were made of scales and that the “dust” you see when you touch a butterflie are actually the scales, that amazed me because I couldn’t imagine how was that possible. A few weeks ago I saw a little black and white wing on the floor…

Leptosporangiate fern

I’m a little too excited because of this pictures. These pictures were taken of a sorus (the brown thing on the leaf) of a fern throw the foldscope and when I first saw them I had no idea of what was I looking at, but I knew I was going to know later because of…

Human blood

Our blood is made of many many cells, water, proteins, etc. In these pictures what we can see are the different types of cells which are part of that red liquid that runs inside our veins and arteries. The cells here can help to transport oxygen and nutrients or can be part of the inmune…

Fresa con moho

La observación de hoy fue una fresa con moho. Encontré en la cocina una fresa que tenía moho. Le corté un pedazo delgado y la colocamos en nuestro portaobjetos. Logré ver muchas líneas delgadas de color negro. Corté un pedazo mas grueso de la fresa con moho. La colocamos en nuestro portaobjetos. Logré ver todo…

Secreción nasal (moco)

La observación de hoy fue la secreción nasal de un bebé. Del estornudo de un bebé obtuvimos nuestra muestra. Tomamos una parte delgada del moco. La colocamos en nuestro portaobjeto y el resultado fue este. En esta otra muestra tomamos un pedazo grueso del moco. Lo colocamos en nuestro portaobjeto para ver sus diferencias. Logré…

Bio60_2021: spinach leaf

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

Bio60_2021: mouth bacteria

(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.

Piel de pepino

La observación de hoy fue la piel de un pepino. Cortamos la piel del pepino. Sacamos una parte fina de la piel y la colocamos en nuestra muestra. Logré ver unas líneas grises y círculos. Sacamos una muestra mas del pepino. Esta muestra es de la piel fina verde. Logré ver solo unas líneas verdes….

Hoja de lavanda

La observación de hoy fue la hoja de lavanda que encontré en el jardín. Logré ver unas líneas delgadas. También vi unas bolitas pequeñas que creo son las células que la conforman.


Rotifers are microscopic animals who live in lakes, ponds and in any humid environment.
