Figure 6: Peony hybrid “Louise Rowe” dicot plant image followed by planar and cross-sectional views of stomata on the leaf underside. The top most layer of a leaf is called the upper epidermis. A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. Photos of specimen preparation are also shown. The hole is made up of twin guard cells and auxiliary cells. In some flowering plants (monocots, such as grasses) stomata are generally oriented similarly to one-another. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Focus on a point above the stoma and note a first reading (in μm) of the stage micrometer. The SAI of at least 30 stomata per leaf was calculated, and three leaves per each treatment / time point were used for statistical analysis.
