Brine shrimp

I got some brine shrimp cyst (Artemia salina) for fish feeding and got to witness its hatching.

Brachiolaria larva

Brachiolaria is the second stage of larval development in many starfishes. it has bilateral symmetry.

Obelia colony

Obelia is a marine colony of hydroid organisms. Each colony of Obelia consists of a horizontal thread-like root called hydrorhiza which is attached to a weed or any substratum ,Obelia is a marine colony of hydroid organisms.

Ovule of Hibiscus and its transverse section

These are the flower’s eggs, located inside the ovary. Upon fertilization by pollen, they will eventually grow into a seed. In fruit plants, pollen will not only spark the growth of a seed, but a surrounding fruit as well.

An Aurelia scyphistoma

The scyphistoma is a sessile, larval (non-reproductive) stage of Aurelia, which in time turns into a strobila. Scyphistoma sometime multiplies by budding from stolons. After some time scyphistoma undergoes transverse fission at its oral end, a process called strobilation.  .

Megalopola

Megalopa larva has a large un-segmented cephalothorax with all 13 pairs of appendages like those of a crab, abdomen is straight and in line with cephalothorax, it is like the abdomen of prawn with 6 pairs of well formed pleopods, In crabs the nauplius is passed in the egg, it hatches as a zoaea which…

Cypris

Cypris are ostracods (a type of crustacean) and related to mussels and shrimp. They are small, about 1/2 – 2mm long, with a hard outer shell. In freshwater ponds they are usually found scuttling around among the debris at the shallow edges. They swim smoothly with appendages extended from between the two halves of their carapace…

Zebrafish embryonic stage

Transition stage between Oblong to sphere stage of blastula period in zebrafish embryonic developement

Skin of Octopus

Chromatophores are organs that are present in the skin of many cephalopods, such as squids, cuttlefish, and octopuses, which contain pigment sacs that become more visible as small radial muscles pull the sac open making the pigment expand under the skin. 

Foldscope, Tardigrade and The Himalayas Part 08

Hey folks, here’s a post about my journey in the Himalayas with Foldscope. Follow me on Twitter and Researchgate to know more. Lets continue… Step right up Folks…. See the infamous Water bears that can survive extreme conditions… Finally one of them caught in the act too… Tardigrade in a circus act… Just look at…

Foldscope, Tardigrade and The Himalayas Part 07

Hey folks, here’s a post about my journey in the Himalayas with Foldscope. Follow me on Twitter and Researchgate to know more. Lets continue… As I mentioned in my earlier post that we are done with the journey, in the subsequent posts I will be discussing about the methodologies to find them. NOW!!! how does…

Posterior Spircale of Chrysomia species

DBT Foldscope scheme “Foldscope for diagnosis of rumen acidosis and parasitic infections in cattle” Here’s a beautiful and detailed picture of the processed Posterior Spiracle of a Chrysomya larvae which was collected from an infected wound of a cow. The steps involved are: The larvae was boiled in 10% NaOH for about 5 mins and was thoroughly…

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.
