1. Reproduction in Seed Plants

2. Life Cycle in Flowering Plants Structure of Flowers – Reproductive organs – Petals  Vary in color; attract pollinators – Sepal  Outermost circle; resemble leaves; enclose the bud

3. Life Cycle in Flowering Plants Structure of Flowers – Stamen  Male parts of the flower Filament: stalk Anther: oval sac where pollen grains are made Filament Anther

4. Life Cycle in Flowering Plants Structure of Flowers – Carpels/pistils  Female parts of the flower Ovary: Contains ovule Style: stalk Stigma: sticky area at top of style

5. Life Cycle in Flowering Plants

7. Pollination – Carried by wind – Carried by animals (more efficient) Bees, birds, butterflies

8. Life Cycle in Flowering Plants Seed and Fruit Development – Ovary walls thicken to form fruit – Encloses developing seeds – If it contains a seed, it’s a fruit!

9. Seeds Dispersal – Animals – Wind & water Dormancy – Embryo is alive but not growing – Needs right temp and moisture to grow Germination – Early growth stage – Absorb water  Cracks seed coat and young root emerges
