The lower layer of cells (the epidermis) was stripped from a lily leaf (with a steady hand!) and stained with Toluidine Blue. By viewing the stained epidermis using a polarised light microscope, the different cells present can be seen, including the guard cells which surround the stomata (mouth like structures which allow gaseous diffusion across the normally impermeable epidermis). The guard cells stain a slightly different colour due to the difference in the chemical structure of the cell walls.
These colourful and interesting microscope photo pendants are 22mm in diameter and measure 34mm from the top of the bail to the bottom of the pendant. The pendants are silver plated and supplied with an 18 inch (45cm) silver plated chain. The image has been printed onto glossy metal which is sealed underneath a glass magnifying dome. As the images are printed onto metal there are reflections from both the metal and the glass resulting in the image having more 'depth'. Great gifts for teachers or recent graduates. Or anyone who has an interest in the world around us.
Supplied in a gift box complete with a description of the image.
