  1. Plants

  2. Plant Classification

  3. Angiosperms- flowering plants • “angi” = enclosed sperma= “seed” • seeds are enclosed in a fruit • Examples: grasses, tulips, oaks, dandelions • Divided into two main groups: Monocots & Dicots • Gymnosperms-cone bearing plants • seeds grow on cones • needle like leaves • usually stay green year round • Examples: pine trees & evergreens

  4. SEEDS [blue] [green] [brown] [red] [yellow] [green] [blue] [red] [yellow] MONOCOT DICOT Scientific name : Phaseoluslunatus Examples:peanut, peas, apples, oak tree, roses, cactus Scientific name : Zea mays Examples: grass, wheat, palms, bananas, lily

  5. Banana Seeds

  6. GERMINATION MONOCOT DICOT

  7. ROOTS • Fibrous • Roots [orange] Tap root [yellow] Secondary roots [purple] DICOT MONOCOT

  8. STEMS Vascular Bundle = xylem + phloem Phloem – carries food and water down Xylem- carries water upward from roots MONOCOT DICOT Vascular bundle Randomly scattered Arranged in circle along outer edge

  9. phloem [green] xylem [yellow] MONOCOT DICOT

  10. LEAVES Parallel veins Most narrow leaf Netted veins Broad leaf DICOT MONOCOT

  11. FLOWERS DICOT MONOCOT Flower parts in multiples of 4 or 5 Flower parts in multiples of 3

  12. Monocots vs Dicots

  13. Parts of a Flower Stigma [F] Anther [M] Petal Pollen (sperm) [M] Filament [M] Style[F] Ovary [F] Sepal Ovule [F] Pistil = Stigma, Style, Ovary, Ovules Stamen= Anther & Filament
