Lets have a flower dissection!

Flower Parts

Petals:
attract pollinating insects such as bees, butterflies, birds and bats to the flowers. Such creatures aid in fertilization

Sepals:
look like small leaves, they protect the flower before it blooms and help maintain the structure by keeping the flower in place

Peduncle:
The stem that holds the flower up, the stalk, the flower is at the top of the peduncle

Receptacle:
the thicker area at the bottom of the flower that holds its organs

Carpel or Pistil:
female part of the plant, located at the center of the bloom, contains the stigma, style and ovary.

Ovary:
located at the base of the flower and has seeds inside known as ovules that turn into fruit.

Style:
the long stalk that supports the stigma.

Stigma:
located at the tip of the pistil, the part of the flower that's sticky and collects pollen, pollen initiates fertilization so that seeds can be created.

There are many types of stigma:

Stamen:
the male part of a flower, produces male reproductive cells, located on both sides of the pistil.

Stamen has two parts:

Anther:
the head of the stamen, produces pollen.

Filament:
the stalk attached to the flower that holds the anther.

When pollinating insects, such as bees and butterflies, go to the flower for pollen, they also visit the stigma and fertilize the flower.
