Question

Organization of the Flowering Plant Body 67 2. Root cross-section kamine a prepared slide of a dicot (Ranunculus) root. Identify the structures in Fig. 8-1: ere are four sections on your slide. Look for a mature section. It will have red cells forming a star shape in the center. b) Observe the model of the root cross-section and key. FIG. 8-7. DICOT ROOT. Epidermis-the outermost tissue of the root, similar to the stem except for the development of root hairs. Cortex-parenchyma tissue which stores starch. This is the largest portion of the root. Endodermis--the innermost layer of the cortex. The cell walls of these tightly packed cells contain asparian strips, a fatty material which forces water to enter the protoplast of the endodermal cells.
