Microscopic photo of a professionally prepared slide demonstrating Plasma cell myeloma from bone marrow aspirate. Wright Giemsa stain.
Epithelial Cells in urine sediment.
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.
plant Pine Stem C.S. under light mircoscope with white background
Photomicrograph of Paramecium caudatum. Consists of only one cell. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Symbolic illustration of infectious viruses under the microscope, for example influenza viruses, smallpox, measles or similar. Medical research and investigation of diseases and healthcare concept.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
3d cell organelle - nucleus (Chromatin,  Rough Endoplasmic Reticulum, Nucleus Shell, Nucleoplasm, Nucleolus)
Euglena is a genus of single cell flagellate eukaryotes under microscopic view for study.
Trematode parasite under a 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.
Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope

TEM micrograph showing a binucleated hepatocyte. The cytoplasm shows many mitochondria and elongated cisterns of rough endoplasmic reticulum (RER). In three micrograph corners, the space of Disse with many microvilli can be seen
Ascaris C.S. under light microscope with white background
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.

Spirogyra algae (filamentous green algae) under the microscope - optical microscope x400 magnification
Structure of Escherichia Coli
amazing inhabitants of the microworld under a microscope
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.
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
corn budding section in light microscopy
Host cells with spores (mold) are inside wood under the microscope for education.
