Exploring Leaf Structures!

This year, Professor Pringle’s EEB321 (Ecology: Species Interactions, Biodiversity and Society) class at Princeton University was given the opportunity to explore the image enhancing capabilities of foldscopes – printable microscopes made for only a dollar each. In class, we each built our own foldscope and were encouraged to explore with it. I focused on attempting…

Outer and inner onion epidermises – stained at home!

The first time I sampled an onion peel was a bit different from the introductory experiment in a biology textbook (I observed the outer epidermis, without staining it). Till now I haven’t been able to get the same “3D” effect again (https://microcosmos.foldscope.com/?p=197449), but today’s observations were equally beautiful! This time, I observed and compared the…

Onion Cells

An onion peel is typically one of the first samples viewed when introduced to school-level microscopy. Here are images of an onion skin under my Foldscope. The cells are seen very distinctly and have a three-dimensional appearance. CookerBird

Flower petal :)

having a foldscope opens a window to the world around me! Still learning how to tweak the phone camera with the magnetic coupler, as my iPhone camera somehow became magnetised and it keeps flapping and moving .. so excited to collect specimens and see everything!

Study of everyday vegetables under foldscope

On a quest to find nice cellular structures with everyday vegetables. I use potato, orange peel, green onion, and shallot here. If anyone knows any vegetable whose cells that are clearly visible under foldscope and any interesting structure, please let me know!

Onion Cells

A  very popular excercise among biology students – a thin slice of onion, i borrowed while mom wasn’t around in the kitchen 🙂 I love the way the bubbles have aligned in the pic too!

Onion Root Tip

Here’s the first foldscope image I’ve ever taken. It is a prepared slide of an onion root tip, stained with acetocarmine to visualise the chromosomes. The onion root tip is a great sample to observe the stages of mitosis, however, most of the division is occurring a bit farther back along the root than where…

How Large Are Plant Cells? (BioE80 Spr 2015)

How big are cells in the plants that grow around us? Luckily, our Foldscope can help!   I first started by taking an image of a flower that was growing outside the classroom:   With the magnification provided by the Foldscope, we can see that there are little rectangular cells that make up this flower. So,…
