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…

“Foldscope” Sunday suprised Me.

While having foldscopy of microalgae sample, I have seen locomotion of some tiny creature, that draged me to take this video. Hope’s you all like it and if any one could share his knowledge regarding this creatures this platform is open for them.

Hairy Rainy Flies

Few more insects which have started to turn up at home this year. Rainy season in Mumbai is a real time for foldscoping. Not just the greenery but the tiny insect community also come into full action. Being the only time where they can be magnified under microscope. I am adding few pictures and videos…
