Filaments of the green algae, Spirogyra, showing spiral chloroplasts, with a glow from polarization in an abstract micrograph taken at 100x.
abstract imagery of a fusion of colors and surfaces
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Pinnularia diatom
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.
Yeast cells, whole mount, 80X light micrograph. Stained smear of Saccharomyces cerevisiae, brewers or bakers yeast, Eukaryotic, single-celled microorganisms classified as members of fungus kingdom.

Water bubbles over illuminated mineral.
Host cells with spores (mold) are inside wood under the microscope for education.
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.

Spirogyra algae (filamentous green algae) under the microscope - optical microscope x400 magnification
Fresh water diatom, a type of algae, Pinnularia species, dividing next to a strand of Spirogrya. Wishing Well, Hwy 146 near west entrance of Pinnacles National Park, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Host cells with spores (mold) are inside wood under the microscope for education.
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.
