Some amoebas like this one form shells. Shell is composed of bits of rock (sand), diatom shells, and other debris. Fresh water. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Freshwater aquatic zooplankton and algae under microscope view
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Happy tardigrade- the water bear- a micro-animal living in moss that looks like it's smiling and dancing, from Shenipsit State Forest in Somers, Connecticut.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Microscopic image of urine granular cast and cellular cast, cause of exercise or dehydration Acute tubular necrosis. kidney diseases.
Trematode parasite under a microscope
Freshwater zooplankton Rotifer or Rotifera Euchlanis by microscope. Wheel animals. Benthic.
Honeybee Mouth Parts under light microscope with white background
Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.
In vitro bacterial culture
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
Amphora sp. algae under microscopic view pattern, Diatoms, phytoplankton, fossils, silica, golden yellow algae
Ephestia elutella, wing of grain moth with scales macro close up under the light microscope, magnification of 40 times, microscope objective 4
Cheyletiella blakei Mite - Small Cat pest view under a microscope
Brown caddisfly trichoptera on white background
Photomicrograph of an ascus with eight ascospores. This preparation was stained with acid fuchsin, which stains the cytoplasm of the ascospores a deep red color. The fungus is an ascomycete, Diplodia corticola, that infects the wood of oak trees, and is one of the causes of oak decline disease.The picture was taken with a microscope equipped with differential interference contrast optical system that gives a three dimensional effect.
close - up of a cat, isolated on white background
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Micro world
Demodex folliculorum - parasitic mite on the eyelashes of a human eye, microscope
\
Paramecium caudatum is a genus of unicellular ciliated protozoan and Bacterium under the microscope.
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Microscopic photo of a thin section of calcareous tufa of Holocene age.
Photomicrograph of Euglena species. Fresh water, California. Live specimen. Wet mount, 40X objective, transmitted bright field illumination.
