SEM of a damaged human head hair with a split end

Scanning electron micrograph (SEM), of a damaged & split end of a human head hair. Hair is a fibrous protein (keratin), which develops out of a tubular hair follicle in the epidermis of the skin. The shaft, the part visible, consists of three layers: an outer layer or cuticle, which is scaly in normal hair but has been lost in this specimen. Beneath is the cortex containing hair colour pigments. The medulla forms the central core, which may be hollow. Hair cells are dead except for a layer at the base of the root where they divide to form new cells, pushing the older ones upward. Magnification: X 185 at 35mm size, 1300 at 8x10-inch size

Upper surface of a pea leaf

Scanning electron micrograph (coloured green) of the upper surface of a pea leaf, Pisum sativum, with the epidermis (left) stripped off (right) to show the palisade mesophyll layer beneath. The waxy epidermis is studded with open stomata, tiny pores that regulate gaseous exchange between the plant & the atmosphere. The palisade cells are elongated & packed closely together. They contain the chloroplasts, cellular organelles involved in the manufacture of starch from the sun's energy, carbon dioxide & water (photosynthesis). During daylight when photosynthetic activity is high the stoma are open, at night or during a water shortage the pores close. Mag: X 100 (35mm). Original Original is B/W print B 745/46M
