Spore bags of helminthosporium contain 8 cells. This disease causes helminthosporiosis of wheat. Soon very small and quite harmful.
High-Res Antique Flower Illustrations from William Curtis – Flora Londoniensis. Published from 1777-1798. (source: original Copies from my own Archive).\nCopyright has expired on this artwork. Digitally restored and optimized in Photoshop by myself.\nModern Nomenclature.
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.
Probiotics, bacteria on white background. Bacteria and microorganisms. Microscopic probiotics, bacterial flora

Freshwater zooplankton Rotifer or Rotifera Euchlanis by microscope. Wheel animals. Benthic.
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.
A plant cell is a fundamental unit of plant life, containing various organelles, including the cell wall, chloroplasts, and a large central vacuole, which are unique to plant cells. These cells serve as the building blocks of plants and play essential roles in photosynthesis, growth, and structural support.
Photomicrograph of Euglena species. Fresh water, California. Live specimen. Wet mount, 40X objective, transmitted bright field illumination.

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.
plant stem (dahlia stem) cross section under the microscope showing epidermis, bascular bundles (phloem and xylem) cortex and pith - optical microscope x32 magnification
Munich 1880-1889,  Germany.  Victorian style botanical lithographs with corresponding  caption in Latin and old German script.

Trifolium elegans suecicum et Trifolium fragiferum
Vintage herbarium on an old textured brown aged paper. Composition of the dry pressed herbs.
Photomicrograph of Volvox globator, a green algae in various stages of development. Dark green spots are daughter colonies forming inside of parent colony. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
