Sampling was done through randomized chosen, which was followed with making preparations using paraffin method after Johansen (1940).<span>&nbsp; </span>Observation on the structural traits of the roots and leaves was accomplished descriptively.<span>&nbsp; </span>Observed parameters were the anatomical structure of roots and leaves, leaf thickness, leaf cuticle thickness, number of stomata per leaf square unit, number of trichome per leaf square unit, and number of motor cell per row. Research result showed that the structural defense traits owned by Sawah rice and Gogo rice was different. It was seen from the observed parameters, i.e. from the measurement on the root air pore diameter, leaf thickness, the thickness of leaf cuticle, number of stomata, number of trichome/mm<sup>2</sup> leaf square unit, and number of motor cell.</span></p>
