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.


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.

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…


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

Pollen of Convolvulaceae

Pollen is that dusty thing we usually see on flowers, but have you ever imagined how it really looks under the microscope? Actually the morfology of the pollen is diverse and it can change a lot from plant to plant, in this one the pollen looks like mini golf balls.


Stomata are pores on the epidermis of the plants and they allow oxigen to get in and carbon dyoxide to get out, water can also leave the inside of the plant from here. These ones are from the epidermis of Crassula ovata. We can see how the epidermical cells are colorless but the stomata are…

Bougainvillea bracts

Many colours are usually found in the bracts of plants of the gender Bougainvillea and it’s very common to confuse them with petals. In this pictures we can see the veins.
