Abstract :
This research aims to give information about cells? structure of the epidermis and stomata on leaves of several macrophytic plants with different habitat types exist emergent plant, i.e. Nelumbo nucifera and Ipomea aquatica, floating plant i.e. Nymphaea alba and Pistia stratiotes, and submerged plant i.e. Hydrilla verticillata. The research had been done at Biology Laboratory FKIP Unsri on January until June 2020. The method used is descriptive method based on observation of paradermal section on the top (adaxial) and bottom (abaxial) surfaces of the leaves by binocular microscope. The results shows that cells? structure of the epidermis and stomata on leaves of macrophyte plants having a variation. Epidermis of the leaves straight shaped and curved shaped. The shape of stomata were amarylliacae. The types of stomata were anomositic and parasitic. The highest stomata index was 24% and the lowest stomata index was 10%. Stomatal distribution types has two different types; Ipomea aquatica has stomata on the both leaves surfaces (amphistomatic). Nelumbo nucifera, Nymphaea alba, and Pistia stratiotes only have stomata on the top leaves surfaces (epistomatic). Whereas Hydrilla verticillata has no stomata.
