Photomicrography of Wet Mounts of Hibiscus Plant Parts & pH Determination of Their Extracts

This structured inquiry lesson deals mainly on the preparation of cross-section wet-mounts of the Hibiscus stem, leaf and flower, and their photomicrography. Additionally, students will prepare the extracts of the Hibiscus stem, leaf, and flower, and determine their pH using the Hydrion (pH paper) and universal indicator. This lesson will allow the students to confirm the microscopic structures of the Hibiscus plant parts that could be observed through the photomicrographs, and infer on the chemical nature (acid, base, or neutral) of the plant extract depending on the determined pH values.

Plant Structure:

Paul Andersen explains the major plants structures. He starts with a brief discussion of monocot and dicot plants. He then describes the three main tissues in plants; dermal, ground and vascular. He also describes the plant cells within each of these tissues; epidermis, parenchyma, collenchyma, sclerencyma, xylem and phloem.
