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.
Curly marble stone with fashion veins.
Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.
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.

Trematode parasite under a microscope
Candida albicans is a species of yeast, a single-celled fungus that reproduces asexually, with daughter cells budding from parent cells. C. albicans is normally harmless and is commonly found on the skin and mucous membranes of the mouth, digestive and respiratory tracts and the vagina. Antibiotic treatment or compromised immune function may, however, lead to C. albicans infection. Common candida infections include oral and vaginal thrush. Coloured scanning electron micrograph (SEM), magnified x3300 when printed at 10cm wide.
In vitro bacterial culture
Transmission electron micrograph (TEM) showing a desmosome (macula adherens) with prominent dense plaques where keratin intermediate filaments were attached.

Epidermis. Electron microscope micrograph of an epidermis spinous layer. The keratinocytes show polygonal shapes, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous desmosomes crossing the intercellular spaces.
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.
