1 { Reproduction in Flowering Plants

2 The Parts of a Flower Most flowers have four parts:  sepals  petals  stamens  Pistil

3 The parts of a flower  Sepals  Sepals protect protect the bud until it opens. Leaves that cover the plant  Petals  Petals attract insects.  Stamens  Stamens make pollen.  Pistil  Pistil grow into fruits which contain the seeds.

4 Stamen (male)  Anther: pollen grains grow in the anther.  Filament: Holds up the anther  When the grains are fully grown, the anther splits open.

5 Pistil (female)   Stigma   Style   Carpel (ovary)   Ovules (eggs)  1  1 in each plant. Located in the center

6 Label the Pictures

7 Pollination  Flowering plants use the wind, insects, bats, birds and mammals to transfer pollen.  Pollen moves from the stamen part of the flower to the stigma part of the flower.

8 Pollination  A flower is pollinated when a pollen grain lands on its stigma.  Each carpel grows into a fruit which contains the seeds.

9 Seed dispersal Seeds are dispersed in many different ways:  Wind  Explosion(Eject)  Water  Animals(birds,  Animals(birds, dogs…)

10 Wind pollination  Some  Some flowers, such as grasses, do not have brightly coloured petals and nectar to attract insects.  They  They do have stamens and carpels.  These  These flowers are pollinated by the wind.

11 How animals help seed dispersal  Some  Some seeds are hidden in the ground as a winter store. fruits have hooks on them and cling to fur or clothes.

12 How birds help seed dispersal  Birds  Birds and animals eat the fruits and excrete the seeds away from the parent plant.
