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…

Section of Lotus Root

On 8th June, 2018, I, along with my fellow students of CMR National PU College at ITPL, Bangalore, observed a section of a lotus root under the foldscope. The root was obtained from a lotus plant growing in pond near my home.  On seeing the root without any aid, the root appeared spongy. When we…

Getting to know my (plant) neighbors Episode 1 – Camellia japonica 椿

Hi Foldscopers! フォールドスコープ探検隊の皆さんこんにちは! I went for a very long walk with a mission, follow a river from the upper watershed all the way down to the mouth. 休日の散歩に、近くを流れる川に沿って上流から河口まで散策しました。 Along the way, I found many kinds of plants, both wild and cultivated. I consider them my neighbors, and I’d like to introduce them to you! And…

Tarragon Spice (Bio60_2018)

Adding to my collection of spices, I decided to write a post about Tarragon which is a rather unnoticed, unknown, but distinct spice. My last post focused on using a dry mount for a dried product, however,  tarragon was flat enough to be used with a wet mount to produce rather satisfying results.   Since…

Onion Cells

I was fortunate enough to be accepted as an initial Beta tester for the Foldscope project.  I have two daughters who love science and I had been contemplating buying them a microscope when I first heard about the project.  I can’t describe how how excited I was to receive our Foldscope package in the mail. …

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…

Hair-like structures inside Carnivorous Plants

Purpose To find structures that carnivorous plants may use to trap and kill insects.   Problem I don´t know what structures do carnivorous plants use to trap and kill insects.   Hypothesis If I use a Foldscope to see the inside of a carnivorous plant, then I will be able to find structures that carnivorous…

Foldscope Day 3: Ants, Pollen, and Berries up close

Ants I stuck an ant under the foldscope. The ant and the foldscope did not disappoint. What looks to the eye approximately like this… …under the foldscope, is transformed into this. So of course, I had to take a video and explore this ant further. Here’s what I saw. Amazingly, the ant is actually translucent,…

Carpobrotus – a pig face plant 

Its a little bit ironic for a plant to be called pig face. Specially when it looks like a beautiful flower. This is a very common plant – carpobrotus – with almost 25 or so species spread all across the coast of California. It would be rare to be at a beach in California and…

Leaf and Trichomes of Cabomba caroliniana

I have a fish tank at home and I am starting to look at samples from it under the Foldscope. Here I studied the leaf of Cabomba caroliniana, a basal angiosperm. It is a fast growing common aquarium underwater plant, with linear leaves. I looked at the leaf with the high powered lens. After discussion…

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.  

A microscopic classic ; onion

As a classic sample of plant cells, here is my onion membrane cells painted with methylene blue.            

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.

Study in Light: Low/High Magnification, Onion Skin and Natural Light.

  The topography of the onion skin delights me and the colors are so beautiful, including a purple impossible to capture. Under lower light, the cell walls look taller than the cytoplasm, and look to be ragged, not as I expected.  The shapes of the cells are interesting, and some are curved, perhaps bulging from…

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…

Patterns in Plants

I love patterns and a few years back I discovered that there are beautiful patterns to be found in plants at a microscopic scale. So I was delighted to find this awesome pattern in a prepared slide of a corn stem: To me, it looks like a bunch of tiny skulls screaming. So delightfully creepy….

Coleus Flower

My first two Foldscope images! These two are parts of a single structure from a Coleus flower.  Since I have minimal training in botany, I’m not sure of what this is called — I welcome any input from other folks on this site.  

Schlumbergera

This post is about the a species of Schlumergera. The specimen is a flower petal from a Christmas Cactus, or so people have named this plant. I do not fully know if it is from the Truncata group or Buckleyi group. The sample was picked by me on the plant. The flower petal was picked…

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…
