Transcript of Flowers

The Anatomy of Flowers
The pistil is the female reproductive organ of the flower that is fertilized by pollen.It is made up of four parts.
The Pistil and the Stamen
The three parts of the pistil are the stigma, the style,the ovule, and the ovary.

The Four Parts of the Pistil
The stamen is the male part of the flower that produces pollen to fertilize the seed.
The anther is the part of the stamen that makes and holds pollen.

The filament is the stalk that holds the pollen sacks.
The Anther and the Filament
The ovary is the part of the plant that has seeds inside and turns into the fruit we eat.
The Style
The Stigma
The stigma is the bulb inside the flower where pollen lands and fertilization begins.It is sticky so it can catch the pollen grains.
The Ovary
The ovary is the part of the plant that holds the seeds and eventually turns into the fruit that we eat.It is usually at the bottom of the plant and is part of the pistil.
The ovule is the part of the ovary that becomes the seed
The Ovule
The Ovule
Petals are the colorful and pretty part of the flowers that attract pollinators.
Sepals look like little green leaves and cover the outside of the flower bud as protection for when the bud blossoms
The Petals and the Sepals
Pollination is the transfer of pollen from the anther to the stigma.Flowers attract pollinators like bees, butterflies, insects, and birds using their sweet nectar,shapes, and bright colors.
The style is the part is the tube like, long stalk that holds up the stigma.
Fruit forms after pollination transfers pollen from the stamen to the stigma and travels to the ovary.Then the ovary becomes ripe and turns into fruit
Why does Fruit Form?
Plants have flowers because the are the reproductive structure of the plant where fertilization takes place.
Why do Plants Have Flowers?
The main reason that most plants produce fruit is to disperse seeds.The fruit protects the seed and provides water and nutrients when the seed starts to germinate.
Why do Plants bear Fruit?
