Round, green chloroplasts in plant cells of anacharis or waterweed, Egeria densa. Chloroplasts carry chlorophyll which makes them green. These chlorplasts actually circulate around within each cell. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Plant anatomy and ecology. Common Bladderwort (Utricularia vulgaris). On filamentous leaves located hunting capsule of insectivorous plant - round animal plankton digested inside. Ultra macro
Calamagrostis arundinacea is a species of bunch grass in the family Poaceae, native to Eurasia, China and India.
Abstract leaf macro background: Moss

Soapwort; Saponaria caespitosa
Great Basin bristlecone pine tree, Pinus longaeva, showing growth habit. Bryce Canyon National Park, Utah, USA. Nov 1979.
Abstract blue stripes from nature, tropical palm leaf texture background
Close up of Mountain plant Sideritis Scardica
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.
Amphora sp. algae under microscopic view pattern, Diatoms, phytoplankton, fossils, silica, golden yellow algae
Freshwater Closterium algae (unicellular charophyte green algae) - optical microscope x200 magnification
Green micro organisms grow in the waters of a runoff field in the Upper Geyser Basin in Yellowstone National Park.
Lepocinclis acus or euglena acus, a single cell flagellate eukaryote under the microscope
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.
Alternaria spore was zoom by transmission electron microscope. Alternaria is a genus of ascomycete fungi. Alternaria species are known as major plant pathogens.
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.
One rigid hornwort isolated on a white background.
Rheum officinale, Chinese rhubarb, Rheum palmatum L.
European Salicornia europaea, is an edible plant that grows in the Wadden Sea.
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.
Cladophora sp. algae under microscopic view, Filamentous green algae, dark background
