Place the nail varnish in the middle of a slide 5. Focus in on the imprint of the leaf's lower surface and observe the stomata. You will need to use x100 or x400 to see the stomata clearly
 * Method:**

• Count the stomata in view on different types of leaf and suggest reasons for the different densities found • Draw and label a stomata including the guard cells and surrounding epidermal cells.
