                    d. Petals = (Corolla) usually colored,
                                attracts pollinators
                    e. Stamens = (Androecium) pollen = male 
                                 gametophyte
                    f. Carpels = (Gynoecium) ovule = female
                                 gametophyte

          D. Anatomical Organization of Stem

               1. Epidermis (can be replaced with Periderm)

               2. Cortex (Collenchyma + Parenchyma)

               3. Discrete Vascular Bundles (Xylem + Vascular     
                  Cambium + Phloem + Sclerenchyma) Separated by   
                  Parenchyma

               4. Pith (Parenchyma)

          E. Anatomical Organisation of Leaves

               1. Epidermis

               2. Mesophyll (Palisade & Spongy)

               3. Vascular Bundles

                    a. Continuous with stem vascular bundles
                    b. Continuous network in blade (Pinnate,      
                        Palmate, Parallel, Dichotomous)
                    c. Can be surrounded by bundle sheath cells 
                    d. Can be associated with sclerenchyma
                    e. Xylem is up
                    f. Phloem is down

     II. Root

          A. Typically below Ground

          B. Functional Roles

               1. Anchorage
               2. Absorption of Water + Dissolved Elements       
          
          C. Morphological Subcomponents

               1. Root apical meristems (Terminal & Lateral)

               2. Hypocotyl & Epicotyl 
                    a. Region of transition between root to stem
                    b. Complex pattern of vasculature, plumbs root
                       xylem & phloem to shoot xylem & phloem

               3. Tap vs Fibrous

          D. Anatomical Organization

               1. Epidermis can be replaced with Periderm
                    a. Root Hairs increase absoptive surface area

                    b. Forces soil solution to go through cytoplasm 
                       instead of cell wall
                    c. Prevents backflow of water from xylem to
                       cortex

               4. Pericycle (Parenchyma, where lateral RAM        
                             and vascular cambium originate)
