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.
Interesting and unusual science earrings ideal for anyone interested in science and the natural world.
Earrings are printed onto one side of 0.5mm thick Aluminium (reverse side plain Aluminium finish) to give a lightweight and durable glossy and scratch resistant earring. Aluminium discs measure 16mm in diameter and are mounted on either silver plated or hypoallergenic surgical steel earring wires (please choose from the drop down menu). Please note that due to the nature of the metal the surgical steel hooks are slightly less bright and shiny than the silver plated ones shown in the image. They still look great though! Total length from top of earwire to bottom of disc 32mm.
Supplied in a gift box complete with a description of the image.
