Plant tissue  under a microscope
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.
The Microscopic World. Onion epidermis with cells.
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.

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

Photomicrograph of cells in onion skin, Allium cepa. Nuclei visible as small spots in cells. Live specimen stained with iodine. Wet mount, 10X objective, transmitted brightfield illumination. Note - very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Secondary cell wall in rings inside dead and empty hyaline cells of the Magellanic Peat Moss, Sphagnum magellanicum, with polarization at 1,000x.
Full Frame Shot Of Leaf
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.
