The nematode Steinernema feltiae under the microscope, the species used as a biopesticide to infect fungus gnats in agriculture and gardening.
Photomicrograph of Euglena species. Fresh water, California. Live specimen. Wet mount, 40X objective, transmitted bright field illumination.
Yeast cells - 3d rendered image SEM (scanning electron micrograph) view of cells of brewer's yeast (Saccharomyces cerevisiae).  It is used in the production of beer, wine and bread.
Duckweed root, microscope magnification, darkfield microscopy

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.

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.
Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
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.
Host cells with spores (mold) are inside wood under the microscope for education.
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.

Ascorbic Acid is a natural water-soluble vitamin, Vitamin C. Ascorbic acid is a potent reducing and antioxidant agent that functions in fighting bacterial infections, in detoxifying reactions, and in the formation of collagen in fibrous tissue, teeth, bones, connective tissue, skin, and capillaries.

Euglena is a genus of single cell flagellate eukaryotes under microscopic view for study.
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.
