Question

Describe the structure of a flower in detail.

Answer 1

Flower:

In the flowering plants, reproductive structures are present called flowers.

Parts of flower:

Flower consists of a flower whorl and stalk with which the flower is attached to the main axis of the plant.

Pedicel and receptacle:

1. Pedicel is the stalk of a flower through which it is attached to the stem.
2. The pedicle continues to form a swollen tip called the receptacle.

Major parts of the flower are sepals, petals, stamen and carpels.

1. Sepal/Calyx: Sepals are the green-colored portion beneath the petals. Sepals help in protecting the rising buds.
2. Petal/Corolla: Petals are the bright-colored part of the flower that attracts bees, insects, and birds in which color may vary from plant to plant.
3. Stamen/Androecium: Male reproductive parts are known as stamens or androecium which produce pollen grains. Two parts of the androecium are anther(swollen tip) and filament(stalk).
4. Carpels/Gynoecium: Female reproductive organs are called pistils or carpels. These are the innermost parts where seed formation takes place. It consists of three parts- Stigma, style, and ovary.

• Stigma- Swollen, receptive portion of the pistil.
• Style- Long tube-like structure connecting the ovary and the stigma.
• Ovary- Bottommost region where ovules are present and seed formation takes place.
