Caption: Light micrograph of the surface of a leaf from the plant Tradescantia sp. , showing three stomata. Stomata are pores in the leaves & young shoots of plants. They function in the exchange of gases between the plant & the atmosphere. Each stoma is controlled by two "guard cells", which open & close the pore. Magnification: x25 at 35mm size.
