Cheyletiella blakei Mite - Small Cat pest view under a microscope
Microscopic photo of a thin section of calcareous tufa of Holocene age.
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.
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.
In vitro bacterial culture

Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
Protozoa and Green Algae in waste water under the microscope.
Looking through a window underwater where limpets and saline have grown over window.
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.

Mediterranean Jellyfish Cotylorhiza tuberculata Cassiopea isolated on white up and down views
plant Pine Stem C.S. under light mircoscope with white background
Dinophysis algae under microscopic view, Chromista, diatoms, phytoplankton, fossils, silica, golden yellow algae
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.
The plant roots under the microscope
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.
Lillium anther under Optical 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.
amazing inhabitants of the microworld under a microscope
Slice of natural crystal for patterns and textures use with high resolution.
Flukes infestation (parasite) under microscope view.
Oviduct T.S. under light microscope with white background
Algae under microscopic view, Chrysophyte, diatoms, phytoplankton, fossils, silica, golden yellow algae
