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…

Coupling hack for large phone cameras and iPhone focus shaking

I always had a few problems while taking photos of observations under my Foldscope. One was that the magnetic coupler hole is way too small to fix onto any phone camera without blocking some part of the camera.

Sneak peek into the nutty almonds

My very first sample and observation with the foldscope is this almond seed coat! I routinely soak the almonds every night to have them in the morning. Today morning as I peeled soaked almonds, I was just curious as to how they would appear under the microscope. The seed coat was peeled off, dried and…

Stomata and Guard Cells

I observed the outer epidermis of a leaf and the skin of a pea pod under my Foldscope. The samples were taken at different times of the day, and we can see both closed and open stomata, depending on when they were taken. Closed Stomata This is a leaf peel from a rhoeo (Tradescantia spathacea)…

Onion Cells

Getting nerdy about tea bags!

This post can also be viewed on my website: https://kanika-khanna.com/getting-nerdy-about-tea-bags/ I recently took out my foldscope from its storage bin after almost a year. But as the saying goes, it’s never too late to start exploring. I stepped out of my home into our street here in Palo Alto and took some pretty images of…

Amazing experience with Epiphyllum oxipetalum

Epiphyllum oxypetalum is often described as ‘Queen of the night cactus’.

In any case there is a lot of mystique associated with this plant. It blooms sometime between…
