They often have showy petals and fragrances to attract pollinators such as birds, bees, and other insects. Most flowers have four main parts: petals, stamen (anther and filament),
pistil (stigma, style and ovary)
, and sepals. After flowers are pollinated and fertilized, they produce seeds in the ovary of the flower.

- Flower Pollination. Flowers are where pollination takes place. …
- Seed Production. When pollination occurs in a flowering plant, the male pollen enters the female ovary containing female ovules. …
- Fruit Production. Fruits are seed coverings. …
- Fruit Function. Fruits protect seeds.

What is the most important of a flower?
The Functions Of Flowers
One of the most critical functions of flowers is
pollination
. The pollen of the flower comes from the stamen and contains the gamete, the male reproductive organ. … Some plants have flowers with stigma and pollen. This allows them to pollinate themselves.
What is the most important function of a flower?
The primary purpose of the flower is
reproduction
. Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
What is the most important part of flower?
Flowers are the reproductive parts of the plant. Therefore the most important parts of the flower are
anthers
which contain pollen grains and the pistil (stigma, style, ovary) which receives pollen grains then style take it to the ovary and male and female nuclei fuse to form zygote.
What are the important parts of a flower?
Most flowers have four main parts:
petals, stamen (anther and filament), pistil (stigma, style and ovary), and sepals
. After flowers are pollinated and fertilized, they produce seeds in the ovary of the flower.
What is the job of a flower?
The male and female parts are surrounded by the petals of the flower. In many flowers, it is the job of the
petals to attract insects
, so that pollen can be transferred to other flowers. This process is called pollination. The pollen then joins together with, or fertilizes, the ovules, and produces new seeds.
What is center of flower called?
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. … The style leads to the ovary that contains the female egg cells called ovules.
Which is the longest flower?

Rafflesia arnoldii
. This rare flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds!
