Pollen grain of Lily flower
Pollen grains contain male gametes. When the pollen lands upon the female stigma of another Lily flower, the pollen grain germinates. A tube grows out of the pollen grain through the stigma; the male nuclei pass down this tube and fuse with the female ovules.
Proboscis of a Moth.
Moths have very long proboscis, or tongues, which they use to suck nectar or other fluids. These proboscis are very tightly coiled when not in use, like a hosepipe. When in use, the proboscis are uncoiled to their full length and in some species, that length is remarkably long.
Feather of Peacock
We observed the feather of peacock under foldscope and learned about the cells of rachis. The feather consist of Vane, Rachis, Barbs and Hollow shafts. The rachis contains pith, which is composed of air-filled keratinised epithelial cells surrounded by a solid keratinised outer cortex. … Barbs: The series of branches fused to the rachis, constituting the major surface area of…
Polytene Chromosome from salivary glands of Chironomus Larvae
Polytene chromosomes are giant chromosomes common to many dipteran (two-winged) flies. They begin as normal chromosomes, but through repeated rounds of DNA replication without any cell division (called endoreplication), they become large, banded chromosomes. Polytene chromosomes are usually found in the larvae, where it is believed these many-replicated chromosomes allow for much faster larval growth than if the cells remained…
Teacher Training in Assam
Xylem and pholem of a plant Xylem and phloem of a plant studied in foldscope as part of teachers training in Assam conducted by CEE North East. Four schools have been selected near the Deepor Beel, a Ramsar wetland to study the microorganisms. The teachers trained will guide the students to use foldscope given to…
Trichomes
Trichomes serve a variety of functions, depending on their location. As root hairs (and as leaf hairs in epiphytes), trichomes absorb water and minerals. As leaf hairs, they reflect radiation, lower plant temperature, and reduce water loss. They also provide defense against insects.
Twinning program between Foldscope teams of The D. G. Ruparel College, Mumbai and Bijni College, Assam.
On second day under Twinning Program, we explored the campus of Bijni college and collected botanical and water samples. the samples were of different kinds of leaves, flowers and water samples. We prepared slides of the collected samples and observed them under fold-scope. We observed different kind of stomata, pollen, spirogyra and mosquito larvae. We…
Compound eye
Compound eyes of Cockroach under Foldscope.
Wing of Carpenter Bee
The wing in nature looks black, but after looking under foldscope it was totally different.
Observed the head and tail part of zebrafish
In the tail region we can see the vertebral arrangement along with the caudal fin. Eyes are the first thing to be observerd, they are mezmerizing. The fries were of 72 hrs when observed.
Antennae of male mosquito
Mosquitoes use their antennae as movement receivers that respond to oscillations of air particles within the insects’ surroundings. The brush-like male antennae are sensitive to sound waves, particularly to those of the frequency of the wingbeat of females; so when a male midge ‘hears’ a female with his antennae, he flies towards the source of…
Chironomus larvae
Head part of chironomus larvae.
Elodea plant cell
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. It is transparent, but…

Epidermis of a Croton leaf
I, along with my fellow students of CMR National PU College at ITPL, Bangalore, observed the epidermis of a Croton leaf on 8th June, 2018. The leaf used for the observation was that of a croton found in my garden. Care was taken to ensure that we use the epidermis from the part of the…
Section of Lotus Root
On 8th June, 2018, I, along with my fellow students of CMR National PU College at ITPL, Bangalore, observed a section of a lotus root under the foldscope. The root was obtained from a lotus plant growing in pond near my home. On seeing the root without any aid, the root appeared spongy. When we…
