The Microscopic World. Onion epidermis with cells.
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.

Pin Cushion Sea Star Culcita novaguineae occurs in tropical Indo-West Pacific in a depth range from 0 to 90m, max. diameter 30 cm. It is very common in lagoon, back reef and reef front. It feeds on detritus and on sessile invertebrates, sometimes including hard corals, but can not be considered a serious threat for the coral reefs.\nThis species has short arms and an inflated appearance and resembles a pentagonal pincushion. The colour is extremely variable: beige, brown, red, yellow, green, with plates and tubercles often in contrasting colour compared with the background. \nThis is a close-up of the underside, of the oral surface near the centre  with the mouth. \nLembeh Strait, Indonesia\n1°28'8.917 N 125°14'39.105 E at 23m depth
Onion epidermis, whole mount, 20X light micrograph. Large epidermal cells of Allium cepa. Single layer, each cell with wall, membrane, cytoplasm, nucleus and large vacuole, under light microscope.

A high-magnification microscopic image reveals the intricate internal anatomy of *Ancylostoma caninum*, a type of hookworm nematode. The stained specimen vividly displays its elongated body, prominent pharynx, and characteristic coiled gonads against a bright, circular field of view. This scientific illustration is ideal for educational, medical, and veterinary contexts related to parasitology and helminthic infections.

The skin tissue cross-section shows the internal layers of human skin arranged from the outer surface to the inner region. It highlights the structure and function of each layer. The epidermis is the outermost layer of the skin. It acts as a protective barrier against germs, chemicals, and water loss. This layer is mainly made of epithelial cells and contains melanocytes, which give skin its color.
This vivid microscopic image captures a transverse section of two adjacent Ascaris lumbricoides nematode uteri, showcasing numerous developing eggs. The vibrant pink and purple stained structures, seen through a circular field of view, highlight the intricate reproductive anatomy of this common parasitic roundworm. It serves as a valuable visual for biological study, medical education, and parasitology research.
