Found across the midwest United States, the buckeye butterfly has thousands of individual scales on the wings which make up colorful eyespots and the ability to fly.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
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.

stx2a is a subtype of Shiga toxin-producing E. coli (STEC) linked to Hemolytic Uremic Syndrome (HUS), a severe condition impacting kidney function and blood clotting. STEC poses a significant risk of foodborne illness and can spread within communities including family members.
Transmition Electron microscopy of an epithelial cell where mitochondria of several sizes can be seen with the characteristic double membrane and internal cristaes. Mitochondria are believed to be of bacteria origin. It has its own genome and RNA and protein which are similar to those of bacteria.
In vitro bacterial culture
Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.

Frozen coffee under the microscope and in polarized light.
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.
Microscopic image of urine granular cast and cellular cast, cause of exercise or dehydration Acute tubular necrosis. kidney diseases.
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.

Tardigrade (water bear) isolated from moss. Microscopic picture, 40 times magnified.
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
