Plant stomata under foldscope
On the outer layer of the leaf of a plant are microscope holes called stomata. Typically stomata open during the day to allow for the movement of gases in and out of the leaf. Stomata open and close to allow the intake of carbon dioxide and release of oxygen.
Aspergillus niger under the foldscope
Aspergillus niger is a fungus and one of the most common species of the genus Aspergillus. It causes a disease called “black mold” on certain fruits and vegetables such as grapes, apricots, onions, and peanuts, and is a common contaminant of food. It is ubiquitous in soil and is commonly reported from indoor environments, where…
Ophryoscolex purkynjie in rumen fluid
DBT scheme –“Foldscope for dignosis of rumen acidosis and parasitic infection in cattle”. Protozoa under the genus Ophryoscolex Ophryoscolex purkynjie protozoa present in the rumen fluid of cattle was identified by methyl green staining using foldscope. Ophryoscolex purkynje body is characterized by the long caudal spinatin. Rumen fluid was collected from a healthy cow. Smear…
Compound eye of Chironomidae
Midges (Chironomidae) are the most wide spread and numerous insects resembling mosquitoes. Adult Midges are commonly observed flying in swarms or “clouds”, or are seen resting on fences, walls, under eaves and in protected areas such as porches and entryways. https://napamosquito.org/vectors-and-pests/mosquitoes/harmless-mosquito-like-insects/

Entodinium longinucleatum in rumen fluid of cattle
DBT scheme –“Foldscope for dignosis of rumen acidosis and parasitic infection in cattle”. Protozoa under the genus Entodinium Entodinium longinucleatum protozoa was identified using foldscope.Entodinium longinucleatum is ellipsoid, flattened and it is found in the rumen of cattle.Rumen fluid was stained by methyl green.
Fungi observed on onion through foldscope
Aspergillus on onion, collected black powder from the onion cover on to aslide, added a drop of Lactophenol blue and observed under Foldscope, Aspergillus with Hyphae and Spores.
Pollen grains under foldscope
Pollen grains of hibiscus under foldscope Pollen is a small grain that consists of a few cells. To the naked eye it appears as a yellowish dust like substance that is either dispersed by wind or insects. Pollen is formed within the sacs in the anthers that are located in plant flowers.
Onion cells under the foldscope
An onion is made up of layers that are seperated by a thin membrane. For this experiment, the thin membrane will be used to observed the onion cells. It can be obtained by peeling it from any layer of the onion using tweezers.

How can jellyfishes sting?
My city has a wonderful nearby beach known as Las Canteras beach. Last wednesday there were many jellyfishes on the sea shore belonging to Pelagia noctiluca species, cnidarians that the waves drag and leave on the sand when they bloom due to higher sea temperatures, among other reasons. I have always wondered how cnidocites (stinging…

Microbial diversity in a paddy field water sample — Part 3
TWO WORMS Nematodes were in the sample right from Day 1. I was a bit neglectful of them perhaps because, in the numerous samples that I have observed till today, this guest has always been ready to come under my Foldscope. It was on Day 2 that I observed two new worms, one with long…
Microbial diversity in a paddy field water sample — Part 2
DIATOMS, ROTIFERS and SOMEONE UNIQUE The water drop sample from the paddy field further showed moving diatoms and rotifers. One particular organism puzzled me. At first, from its bifurcated tail, I thought it was a rotifer. But on better focusing, I observed its cilia. Was it a ciliate? It seemed too big for a ciliate….
Microbial diversity in a paddy field water sample — Part 1
Hello Everyone! My explorations with the Foldscope constantly enrich me with interesting experiences of the beautiful and dynamic microbial world, and water samples from different places add a special excitement to my life! My family members know this, so recently my nephew gifted me some water from a paddy field (see Image 1). This water…
‘Nitrogen Fixer’ under my Foldscope.
These are the nitrogen fixer Cyanobacteria (Blue green algae) under order Nostocales. They have this ability due to a specialized cell, known as Heterocyst. Heterocyst identification key Features with respect to vegetative cells. Thick walled. Weak pigmentation. Present at both intercalary and terminal position. Intercalary Heterocyst have Polar granules at each pole while Terminal Heterocyst…
Foldscope Puzzles (for me)
Foldscope is giving daily puzzles and each water sample is with variety of organisms in this rainy season. Observed a small creature in a water sample and it is moving very swift, creating pendulum like movement from anterior to posterior end, body looks like segmented and fore limbs like structures are seen, can see the…
What’s this cute one?
Observed a tiny ( of course all are tiny and microscopic, ) very small little one moving on Oscillotaria, (observed at 140 X of foldscope and 4x of mobile ) in a pond water sample
