INSTRUMENTS AND MATERIALS : -
Slide, Cover slip, Microscope, Dropper, Blotting paper, Tradescantia leaf, Water, Glycerine, NaCL solution, KCL solution.

Maximum number of stomata are visible as the lower epidermis has more number of stomata. In Hibiscus and Nagarvel the guard cells of stomata are been shaped while in Maize they are dumb-bell shaped.

Conclusion :

By this method stomata can be seen and counted under the microscope.

Application :

This is an easy method to show the stomata to the students.
