Early stage, two days, fertilized human eggs before transfer to the woman in an IVF procedure.
Freshwater Closterium algae (unicellular charophyte green algae) - optical microscope x200 magnification
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.
Cotton plant root, under the light microscope. Longitudinal section through the root of Gossypium hirsutum, upland or also Mexican cotton. Light micrograph at 20X magnification. Isolated, over white.
Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Leiden leaf c.s. under microscope
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view
Cross section leaf of plant under the light microscope view for botany education.
Intricate bubble texture macro in bright colors for abstract background. Liquid bubbles lit from below with colors injected into the liquid as a design or art abstract.
Cells consist of a protoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.
Hepatocellular adenoma (HCA; also termed hepatic adenoma) is an uncommon solid, benign liver lesion that develops in an otherwise normal-appearing liver. Typically, HCAs are solitary and are found in young women in association with use of estrogen-containing medications.
3d rendering of biological animal cell with organelles cross section isolated on white. Animal cell with placed text annotations to all organelles
Oviduct T.S. under light microscope with white background
centropyxis aculeata (amoeboid organism) under the microscope - optical microscope x400 magnification
Photomicrograph of algae, Cosmarium turpinii, a desmid. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
amazing inhabitants of the microworld 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.
The study of plant tissues under the microscope in the laboratory.
\
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.
Fatty liver disease (steatosis) is a common condition caused by having too much fat build up in your liver. A healthy liver contains a small amount of fat. It becomes a problem when fat reaches 5% to 10% of your liver's weight.
Dicot plants stem show plant vascular tissue under light microscope view for botany education.
Photomicrograph of
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
Squash preparation of stained onion root tip cells showing late telophase and metaphase stages of mitosis. Bright field illumination on a Leica microscope, Image taken with the X100 objective lens.  Depth of focus is extremely shallow (less than one micron).  Optimum setting of the aperture for maximum resolution and good contrast. Chromatic aberation is inevitable in light microscopy, especially at this scale of magnification, but has been kept to a minimum in this image.
