Leiden leaf c.s. under microscope
Stem of Nerium indicum T.S. under light mircoscope with white background
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.
Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
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.
Backgrounds of Bacteria and Mold under the microscope in Lab.

Pine mature wood cross section. Light microscope slide with microsection of an evergreen conifer in the genus Pinus. Plant anatomy. Biology. Photo.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Dicot plants stem show plant vascular tissue under 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.
Internal structure of an animal cell, 3d rendering. Section view. Computer digital drawing.
Liver Fluke Section under light microscope with white background
Bronchitis and alveolitis in lung of horse infected with equine influenza virus, 200x magnification.
Follicular lymphoma is the most common type of of low-grade non-Hodgkin lymphoma (NHL). It develops when white blood cells cluster together to form lumps in your lymph glands or organs. There are two main types of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma.
Photomicrograph of flatworm,
Microscopic close view of high vaginal swab Gram stain smear, 100x. diagnosis of Bacterial vaginosis (BV).
Diffuse large B-cell lymphoma, or DLBCL, is a cancer that starts in white blood cells called lymphocytes.
Gram-negative, rod-shaped bacteria are a type of bacteria characterized by their appearance under a microscope and their cell wall structure. They have a thin peptidoglycan layer sandwiched between two lipid membranes, which makes them more resistant to certain antibiotics compared to Gram-positive bacteria. Common examples include Escherichia coli (E. coli), Salmonella, and Pseudomonas aeruginosa. These bacteria can cause a wide range of infections in humans, ranging from mild gastrointestinal illnesses to severe systemic infections, and they play significant roles in both environmental and clinical settings.
Close-up shooting of a green agate stone mineral surface isolated on white background. Its a macro shot shows nature beautiful details with back lit. Agate is a kind of natural gemstone. Abstract pattern. Good for Wallpaper texture background. Turquoise, blue
Green algae cells background
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.
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.
Photomicrograph of newly hatched freshwater leech. Note multiple eyes at head and second attachment sucker at tail. Body length approx. 3 mm. Live specimen. Wet mount, 5X objective, transmitted brightfield illumination.
