Raspberry rust is a malignant disease caused by the phytoparasitic fungus Phragmidium rubi-idaei. This pathogen forms small ulcers on the leaves through which a huge mass of orange spores breaks through. Under a microscope, this pathogen does not look so sinister.

Cell structure Hydrilla, view of the leaf surface showing plant cells under the microscope for classroom education.
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Uric acid crystal, Calcium oxalate dihydrate in urine sediment.
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.
Tafamidis is a medication used to delay loss of peripheral nerve function in adults with familial amyloid polyneuropathy. 3d illustration

Epiphytic diatom, cells grow on a common stalk that is attached to rocks or algae.
Kerria japonica, commonly called Japanese kerria or Japanese rose, is a graceful, spring-flowering, deciduous shrub that is native to certain mountainous areas of Japan and China. It grows to 1-2m tall on slender, arching, yellowish-green stems. Single, five-petaled, rose-like, yellow flowers bloom somewhat profusely in spring.
Cyclic adenosine monophosphate is a second messenger important in many biological processes. cAMP is a derivative of adenosine triphosphate and used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway. It should not be confused with 5'-AMP-activated protein kinase.
