Stomata

My first attempt of using Foldscope and I was totally amazed. After using Foldscope once I have now nurtured many ideas, and now I am looking forward to feed my curiosity.

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…

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. …

How to fold a leaf? 

Origami is not just an art or engineering discipline. Deep ideas from a Origami also apply to biology. Starting with development of any organism. In fact, if I said that all the diversity of multicellular animal life is just different folds of the same substrate – I won’t be totally off.  To understand the depth…

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.            

Science Photo Foldscope Images

Tilia Meristematic Stem c.s. Psilotum Sporangia l.s. Psilotum Sporangia l.s. Psilotum Sporangia l.s. Phycomyces Blakesleeanus Burg. Zygosporen     These photos were taken on a Foldscope using a low mag lens in combination with a Galaxy Note 4 phone camera. The first 4 are botanical samples, and the last image is a fungi. They were…

Trichome: unusual plant hair 

Did you kno; just like animals, plants also have hairs. That as quiet a surprise when I first learned about the same. More surprising though is the diversity of form and function found in plant hair.  To explore this idea; I just took one single flower and searched for a number of hair geometry on…

Pollen from Hibiscus flower

Pollen grains from an unknown Hibiscus sp. The grains were collected by gently dabbing a tape slide against the anthers. Also included are some photos of the flower and plant the pollen was collected from.

Plants!

Hello everyone, I am super excited and grateful for having  received some Foldscopes today! After constructing one, I eagerly zoomed into the microcosm of plants. The above picture was a sample of a leaf from a manzanita (Genus Arctostaphylos). What are the darker pigmented spots? I thought they were the organelles, possibly the chloroplasts.  …

Fat plants!!

Summary: Fat plants – or often called Succlent plants have surface morphologies quiet different from common plants we are used to seeing. I wondered, what’s on the surface? Often, walking around I have noticed these nice juicy fat plants. Often termed as Succlent plants. Last time, I picked one up; it has a surface texture that…
