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.
Phospholipid bilayer membrane structures that make up living cells and their contents. This is an image of membrane proteins in the membrane.\nThis image, which looks like a plastic model, evokes biology and biochemistry. It can be used as a cover for magazines, textbooks and presentation materials.\nThis image was not created by AI.

Aligned amino acid sequences of various individuals. The amino acids were derived from their three bases in the genetic code and seen in a DNA sequence. This type of alignment is useful in determining the relatedness of individuals. In this case the sequences were derived from the ribosomal genes of a somewhat obscure fungus not known to be of any commercial, industrial or other value.

Extreme Close-up of Coho Salmon Scale
False colour electron microscope micrograph showing the Golgi apparatus (blue), mitochondria (green), very dilated RER cisterns (pale yellow) and secretory granules (dark red) in a gonadotropic cell.\
Right lateral surface of a Common Lionfish Pterois volitans. The species inhabits lagoon and seaward reefs from turbid inshore areas to depths of 50 m, max. length 38cm. Often solitary, they hide in unexposed places at daytime often with head down and practically immobile, using the pattern for camouflage as a hunting skill. The species has recently invaded Western Atlantic and Caribbean coral reefs, and may become one of the most ecologically harmful marine fish introductions to date. The dorsal fins are venomous, but it is a popular table fish. This specimen is from Triton Bay, Indonesia, 3°51'48.03 S 133°55'48.96 E at 18m depth by night
Seamless houndstooth pattern, Crowbar print illustration.
Photomicrograph of rotifer. Rapidly rotating cilia at top of head, internal organs visible. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Photomicrograph of Histological analysis of Intramedullary SOL showing Astrocytoma, WHO grade-4
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.
Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.
