Upcoming Events Think About It Why would a floral designer need to understand a plant functions & structure? Blooming Flowers Plant Structure All artists need to understand characteristics of the items they use to create designs Plant Morphology is the study of the physical form and external structures of the plant materials Plant Anatomy is the internal structure of plants A designer who completely understands the materials can use them to their fullest potential! Purpose of Flowers ○ ○ Reproduce Pollinate We use them to bring life into our homes, send them to friends and loved ones, express our condolences, or as forms of art & beauty. Inside the Flower Sepal protect buds & forms the calyx style Petals attracts pollinators anther Stamen male part ● filament (stalk that holds anther) ● anther (produces pollen) Pistil female part ● ovary (female egg location) ● stigma (where pollen lands) ● style (leads to the ovary) stigma filament petals Complete has all 4 major parts (Roses & Tulips) Incomplete lacks 1 or more of the major parts (Calla lilies) ovary sepal Purpose of Leaves ○ Photosynthesis ● converting nutrients, water, carbon, dioxide and sunlight into food for plants We use them to showcase patterns, textures and to add focal interest in arrangements. Inside the Leaf Midrib leaf’s skeleton & provides mechanical support Petiole structure that connects the leaf base to the stem Apex tip of leaf Leaf Blade portion of the leaf that contains the blade Leaf Base where the leaf attaches to the stem Stems Stems move water and nutrients to other parts of the plant and supports the leaves, flowers and fruit ● xylem cells: move water ● phloem cells: move food Nodes are an area of growth where new leaves or flowers are produced and the area between the nodes are called the internode Roots Roots are the foundation of plants 4 Major Functions ● Support and anchor the plant ● Absorb & carry water and minerals ● Store food & minerals ● Provide a source of vegative reproduction (plants that reproduce from cuttings taken from a leaf or stem) in certain plants African Violets→
