Plant Parts - Flowers
Flowers not only look pretty but, in fact, are important
in making seeds. Flowers have some basic parts. The female
part is the pistil.
The pistil usually is located in the center of the flower
and is made up of three parts: the stigma,
style,
and ovary.
The stigma is the sticky knob at the top of the pistil.
It is attached to the long, tubelike structure called the
style. The style leads to the ovary that contains the female
egg cells called ovules.
The male parts are called stamens
and usually surround the pistil. The stamen is made up
of two parts: the anther
and filament.
The anther produces pollen (male reproductive cells).
The filament
holds the anther up.
During the process of fertilization,
pollen lands on the stigma, a tube grows down the style
and enters the ovary. Male reproductive cells travel down
the tube and join with the ovule, fertilizing it. The fertilized
ovule becomes the seed, and the ovary becomes the fruit.
Petals are also important parts of the flower, because
they help attract pollinators such as bees, butterflies
and bats. You can also see tiny green leaf-like parts called
sepals
at the base of the flower. They help to protect the developing
bud.
