    • sta men
      • male part of flower
      • makes pollen
    • anther
      • @ tips of stamens
      • make pollen
    •  
      • female part of flower
      pistil
    • imperfect flowers
      • flowers that do not have both stamens & pistils
      Passion Flower
    • composite flower
      • 1 flower made of 100’s of flowers
      sunflower
    • stigma
      • sticky part of pistil
    • 1. 2. 3. 4.
    • sexual reproduction
      • passing of DNA from 2 parents to offspring
    • pollination
      • movement of pollen from stamen  pistil
    • Pollinators
    •  
    • petal stamen sepal stigma pistil anther pollen egg cell ovary ______________ _______ ______________ ______________
    •  
    • Sarracenia flower dissection
      • when sperm & egg cell combine DNA
    •  
    • embryo
      • new plant protected by seed coat
      • taproot
      • fibrous
      • roots
      • leaf has
      • veins that
      • branch out
      • leaf has
      • parallel veins
      • 2 areas of stored food
      • easily split apart
      • seeds have
      • 2 cotyledons
      • 1 area of
      • stored food
      • seeds have
      • 1 cotyledon corn
      dicot monocot bean
    •  
    • monocot
      • plant whose seeds have 1 cotyledon
      Monocot seed: a – Seedcoat b – Endosperm c – Cotyledon d - Embryo
    • dicot
      • plant whose seeds have 2 cotyledons
    • A - seedcoat, B - endosperm, C - cotyledons, D - embryo Dicot seed Monocot seed
    • dicot
      • monocot or dicot ?
    • monocot
      • monocot or dicot ?
    • ways that seeds spread :
    • Coconuts -seeds scattered by water.
    • animals help scatter seeds
    • carried by animals bur
    • asexual reproduction
      • 2 ways: runners & budding
      • only 1 parent (no sperm or egg cells)
      • offspring have same genes as parent
    • Spider plants are common houseplants that can reproduce by growing new plants on long stems called runners.
    • Duckweed is a tiny plant that floats on ponds and is food for ducks and other birds. It is one of the smallest flowering plants, but it reproduces mostly by a kind of asexual reproduction called budding. Little buds form on the plant and drop off to grow as separate plants.
