Spores of Fern

Ferns are reproduced from spores that are gathered in clusters called sori, which are usually on the underside of the fronds. The spores can be yellow, green, brown, or black. The sori are sometimes covered with a membrane called an indusium, which will lift up when the spores are ripe.

Curvularia spp.

Curvularia is a dematiaceous filamentous fungus. Most species of Curvularia are facultative pathogens of soil, plants, and cereals in tropical or subtropical areas, while the remaining few are found in temperate zones. As well as being a contaminant, Curvularia may cause infections in both humans and animals. Curvularia produces rapidly growing, woolly colonies on potato dextrose agar at 25°C….

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.

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.

Observed Euchlanis Rotifer under Foldscope

Euchlanis is a genus of the microscopic invertebrates known as rotifers. Sometimes alternatively referred to as wheel-animalcules, rotifers feature a characteristic circular arrangement of cilia at their front ends that are reminiscent of a turning wheel when they are in motion. In addition to a ciliated corona, or head, Euchlanis species have transparent bodies and two strong toes…

Head part of Mosquito Larvae

The head of the mosquito larva is basically prognathous. The mouthparts, therefore, are considered as anterior appendages. The mandibles and maxillae exhibit a wealth of taxonomic characters that, unfortunately, are not extensively used in mosquito taxonomy. A lateral palatal brush (mouth[/no-lexcion] brush) is borne anteriorly on either side of the mouth. In most larvae, the brushes consist…

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…

Fungus [Plural- Fungi]

Fungi can be single celled or very complex multicellular organisms. This is a mould type of fungus. Moulds are made up of very fine threads (hyphae). Hyphae grow at the tip and divide repeatedly along their length creating long and branching chains. Most fungi can reproduce through both sexual and asexual reproduction. Asexual reproduction occurs through the…

Stomata

My first attempt of using Foldscope and I was totally amazed. After using Foldscope once I have now nurtured many ideas, and now I am looking forward to feed my curiosity.
