Epidermis of a Croton leaf

I, along with my fellow students of CMR National PU College at ITPL, Bangalore, observed the epidermis of a Croton leaf on 8th June, 2018. The leaf used for the observation was that of a croton found in my garden. Care was taken to ensure that we use the epidermis from the part of the…

Foldscope at Neuroscience Congress

After I came back from Stanford, the first thing I did was to show the Foldscope to my family and friends. After that, to Universities. Yesterday, I had the first opportunity to show this device to a large group of people. I was invited to a Neurogical Congress in the Province where I live, Mendoza….

Difference Between Cells of a Rose Petal and Cells of a Rose Leaf

Purpose of the experiment: Determine if a rose’s leaf and petal share the same cells. Problem of the experiment: Does a rose leaf and petal share the same shape of cells? Hypothesis: If the Foldscope is used to observe a rose’s leaf and petal, then we will be able to determine whether they share the…

Stomata!

Following are the images of stomata present on lower epidermis of a money plant. I have taken these images from  Moto G2(8mp camera) and with 140x foldscope lens. I was excited to see how clearly those stomata are seen. In the above photo, there were actually more than one layers of tissues. That is why…

The Cell Arrangement of Leaves vs Flower Petals (BioE80 Spr2015)

As humans, we interact with nature very often, and since I am an explorer, I ask many questions when I go outside. There are so many things we can learn from studying the things that go on outdoors, and today, I decided to explore whether or not there are similarities in the cell layout of…

Looking closer to a leaf

              plant cuticles are protective, hydrophobic, waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs. Cuticles minimize water loss and effectively reduce pathogen entry due to their waxy secretion.  

Red flower petals

For my 1st foldscope pics, I decided to look at the leaf of a nice flower we have in our lab. Sorry for the blur… I think the semi-organization of the spherical cells is neat. Pictures taken with Ipad 3.    

Elodea cells in science class

Students enjoyed preparing elodea leaves on foldscope slides and examining the structure of the plant cells microscopically.

Cells of a “schefflera” leaf – first foldscope use

                  Because of the pretty shitty weather I made my first attempt with the foldscope with an indoor plant. And I have to say that I’m very impressed! Amazing what this small paper thingy is capable of 🙂   First I tried it just with sunlight and…

Bonsai Chinese Elm Leaf

My first time using the phone camera with the foldscope. The photos are a little blurry, but I hope to improve my technique over time. The leaf itself was very small, about 1 cm in length, so there is not a lot of detail. Happy Foldscoping!!

Poinsettia (Euphorbia pulcherrima)

This is my fifth Specimen, but I chose to upload this first. (If I can get some feedback on what I should do differently or what is good about this posting, I would be appreciated as I’m still new at this) This Poinsettia leaf fell today. I cut out a small edge section that includes…
