Moss spore capsule (Tortula muralis var. muralis). Coloured scanning electron micrograph (SEM) of part of the opening mouth of a capsule (spore case) of moss. Mosses reproduce by means of spores at certain times during their life cycle. The spores are dispersed from the mouth of the capsule, dispersal aided by the wind. Magnification x1380
micro-scopic: Moth wing scales. Coloured scanning electron micrograph (SEM) of scales (blue) on the wings of a common clothes moth (Tineola bisselliella). These delicate powdery scales are formed from tiny stacked modified hairs, or setae, made of chitin, a common substance in insect exoskeletons. The iridescence of the colours of a moth’s wings is produced by the diffraction of light by the microscopic ridges on these scales.
Pedicellaria : appendage of sea urchin, ( genus sperosoma : coated / calcified : 100 x magnification ). Pedicellariae are positioned on moveable stalks and are distributed between the spines and tube-feet of sea-urchins. Some of the collagen in the pedicellaria is of the “catch” type, that is, it is at one moment stiff and supportive and, at the next, soft and flexible.

Mesenchymal stem cell, SEM - Stock Image - C015/0282
Colored SEM of a human mesenchymal stem cell (MSC). MSCs are multipotent stromal (connective tissue) cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), and adipocytes (fat cells). . 4500X

The micro-structure of a scale from a butterfly wing. Moth and butterfly wings use pigments to make some colours but physical structures, that affect the behaviour of light itself, to make others. The holes are around 1 micrometre across, about the size of a bacterium. Scanning electron microscopy by Dr Bronwen Cribb, University of Queensland.

Scanning electron microscope images reveal hidden horror and beauty
The hydrothermal worm is so tiny it requires a powerful microscope to see it. The organism, only slightly larger than a bacterium, lives in deep sea near hydrothermal vents that spew hot water from beneath the Earth’s crust. Photo: Phillippe Crassous
Hyssop pollen grains (Hyssopus officinalis) Science Image | 80200693 | Science Image from PSmicrographs
Hyssop pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains from the herb hyssop (Hyssopus officinalis) plant on a petal. Pollen grains are produced in the anthers of the flower and contain the male gametes required for reproduction. Hyssop is a medicinal perennial plant found growing wild in southern and eastern Europe. Its flowers are used as a tonic and a sedative. Magnification: x1470 when printed 10 centimetres wide.
