Abstract marble texture background stock photo, suitable for design.
Diatoms, algae under microscopic view, phytoplankton, fossils, silica, golden yellow algae
Blue Square wooden box filled with blue book replicas
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
Transmission electron microscope micrographs showing the aspect of muscle fiber sarcomere components in longitudinal (below) and transverse (above) sections at the Z-line, I and A bands and H zone
plant rape flower cross section under light mircoscope with white background
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
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.
Freshwater aquatic zooplankton and algae under microscope view
Full size digital screening mammogram of a new breast tumor in the retroareolar region of the right breast causing nipple retraction. An ultrasound guided biopsy was performed diagnosing invasive ductal carcinoma. This is the most common type of breast cancer, accounting for nearly 80% of cases. Breast cancer treatment has come a long way in the last few decades, seeing more funding than any other human disease. The first step to a cure is catching it early with screening mammograms such as this case so that the tumor can be removed before it spreads (metastasizes) out of the breast.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
