The primary purpose of a flower is reproduction.
Since the flowers are the reproductive organs of 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 function of flowers and fruits?
They ripen as seeds mature, and then they help disburse seeds rather than protect them. Fruits help plants spread seeds out, because animals transport and discard seeds when they eat fruits. Fruits also fall off trees and start new fruit plants right next to existing plants.
Why are pollinators attracted to flowers?
Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower’s scent can have particular appeal to bees, and its bright colours may lure the bees in.
Why do flowers attract insects?
Some flowers have scent to attract insects. Many of these scents are pleasing to humans too, but not all – some flowers attract flies with a smell of rotting meat. Colours can’t be seen in the dark, so scent is important for flowers that are pollinated by night-flying insects such as moths.

What attracts pollinators to a flower?
Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower collecting nectar, they are also moving pollen from flower to flower. Certain fruits and seeds will not be produced if their flowers are not pollinated.
Why are flowers attractive?
“The beauty of the flower is a by-product of what it takes for the plant to attract pollinators,” says dePamphilis. From a bee’s-eye-view, the UV colors and patterns in a flower’s petals dramatically announce the flower’s stash of nectar and pollen.
Which flower part attracts pollinators?
Flowering plants have several different parts that are important in pollination. Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky.
