Bdelloidea are microscopic aquatic animals that are related to roundworms, found in freshwater and moist soil. Interestingly, a male has never been observed within the species; females reproduce exclusively by parthenogenesis (without fertilization).
Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells. ~ Our World Through A Microscope
Caffeine crystals by Annie Cavanagh and David McCarthy. This false-coloured scanning electron micrograph shows caffeine crystals. Caffeine is a bitter, crystalline xanthine alkaloid that acts as a stimulant drug.
Page 116 Plate figures 24-26 SEM: scanning electron micrographs of pollen from Nypa fruticans, an extant fly-pollinated palm. Fig 24. Low magnification SEM of an overall grain. This distinctive pollen is meridionosulcate with a spinose-reticulate exine X 2,010. Fig 25-26. Higher magnification SEMs of the exine surface illustrating the length and shape of the supratectally borne spines and the size and shape of the lumina Fig 25 X 4,710. Fig 26 X 20,000.
Coloured scanning electron micrograph (SEM) of a red blood cell squeezing out of a torn capillary. A capillary is the smallest type of blood vessel, often only just large enough for red blood cells to pass through.
