Parts of a Hibiscus Flower:

SEPALS (found at the end of Calyx)

The pointed ends called sepals ae found at the bottom of the flower. The green sepals protects the bud of the flower.

Petals

  • Every flower has multiple petals, which differ in colour depending on the species.
  • The colourful petals attracts animals and insects. This attraction helps ensure the pollination of the flower.
  • The bees and the animals (birds) are called the pollinators and they help to transfer the pollens to the stigma and this process is called pollination.

Female Reproductive organs (pistil)

  • The pistil is the female part of the flower; its function is to produce seeds.
  • The pistil consists of the ovary, stigma and style.  The pistil is a long tubular organ.
  • The stigma is where pollen is collected and it at the top of the pistil. In the middle is the style. This is the section that the pollen travels down to the ovary.
  • The ovary lies at the bottom of the blossom. In some flowers there are several ovaries, but the hibiscus has just one.
  • After fertilisation (pollen travels down to meet the ovules (eggs), the ovary develops to become the fruit and the ovule develops to a seed.

 

Male Reproductive organs (stamen)

  • The male part of the flower is the stamen and is responsible for producing pollen.
  • Anthers are two tube-shaped objects that release the pollen. The anther is usually, but not always, yellow.
  • Anthers sit on a long thin tube called a filament. Together, these organs make up the male part of the flower known as the stamen (anther + filament = stamen). Some flowers have a few stamens, but the hibiscus flowers have hundreds.
