Cleavage period

Cleavage period including stages from two cell to eight cell.

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.  .

Bipinnaria larva

A bipinnaria is the first stage in the larval development of most starfish. It is free-living, swimming as part of the zooplankton. When it initially forms, the entire body is covered by cilia.

ICAR-NBAIR conducts workshop for Mynsain farmers

A daylong workshop for farmers to attest the utility of a ‘paper microscope’ in advocating management practices against microscopic pests in organic farming was conducted by ICAR-National Bureau of Agricultural Insect Resource, Bengaluru in association with ICAR Complex for NEH Region, Barapani at Mynsain village in Ri Bhoi District of Meghalaya in December 2018. Around…

Ameoba

An amoeba, is a term generally used to describe a single celled eukaryotic organism that has no definate shape and that moves by means of pseudopodia. Pseudopodia or pseudopods are temporary projections of the cell and the word literally means “false feet”. The cell uses the pseudopodia as a means of locomotion. The plural of amoeba is…

Cyclops

Cyclops are tiny crustaceans of the family Cyclopidae, also called water fleas. They are usually found in stagnant bodies of fresh water such as wells and ponds in poor agricultural communities in rural or periurban areas. Cyclops are just visible (0.5–2 mm) and can be recognized by their jerky mode of swimming. They feed on…

Oikopleura

Oikopleura dioca, the appendicularians are hermaphrodites and the gonads occupy a relatively large part of the body in mature individuals, sometimes producing the curvature of the trunk of the animal. The length of the tail is three times the length of the body. The tail has a neural chord or notochord, covered by a well-developed…

Embryonic stages of frog

The frog has been historically been used as an amphibian animal model of development due to the ease of observation from the fertilized egg through to tadpole stage. The later metamorphosis of the tadpole to frog has also been studied for hormonal controls and limb development. There have also been many different species used in these developmental…

T.S of liver of rat

The liver is the largest gland in the body. It is located in the upper three regions in the abdomen . Hepatocytes are arranged in hexagon-shaped lobules (classical lobules) about 2 mm in length and 700 μm in diameter. 

T.S of Rat Ovary

The paired ovaries of the rat are grape-like structures that vary in gross appearance and size, depending on the stage of the oestrous cycle. The subgross anatomy of the rodent ovary. Covering its surface is a single layer of modified peritoneal mesothelium, the ovarian surface epithelium (OSE), which is continuous with the broad ligament (mesovarium)…

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. 

Radula of Octopus

In molluscs a rasp-like structure of tiny teeth used for scraping food particles off a surface and drawing them into the mouth. The radula is analogous to a tongue and is used to aid in feeding and rasping through the shells of its prey.

Workshop on “Foldscope: Paper Microscope” at NCMR-NCCS, Pune, Maharashtra

A student exposure tour comprising of 13 students and two assistant teachers from MeECL Secondary, School and two ICAR for NEH Region project staff (one JRF and one project assistant) to NCMR-NCCS, Pune, Maharashtra was carried out from 8th to 18th November, 2018. Four days orientation workshop on “Foldscope: Paper Microscope” (under DBT Funded Project) was…
