Flower and Reproductive Structures of Plants
Introduction
A flower is the most beautiful and important part of a plant. It is the reproductive part that
helps plants to produce seeds and fruits. Flowers are found in many shapes, colors, and
sizes. They attract insects, birds, and other animals for pollination.
Main Parts of a Flower
A flower generally has four main parts:
1. Sepals – These are the green, leaf-like parts that protect the flower when it is a bud.
2. Petals – These are the colorful parts that attract insects for pollination.
3. Stamens – These are the male reproductive parts.
4. Carpels (Pistil) – These are the female reproductive parts.
Male Reproductive Structure (Stamen)
The stamen is the male reproductive part of a flower. It has two main parts:
• Anther – It produces pollen grains that contain male gametes.
• Filament – It is a stalk that holds the anther in position.
Female Reproductive Structure (Carpel or Pistil)
The carpel is the female reproductive part of a flower. It has three main parts:
• Stigma – The sticky surface where pollen grains land.
• Style – A tube-like structure that connects the stigma to the ovary.
• Ovary – The swollen part at the base that contains ovules. Each ovule has a female gamete.
Diagram Description
A typical flower diagram shows all parts clearly labeled: sepals, petals, stamen (anther and
filament), and carpel (stigma, style, and ovary). The anther and stigma are positioned to
help in pollination. The ovary lies at the center of the flower.
Functions of Flower
• Helps in reproduction of plants.
• Attracts insects and birds for pollination.
• Develops into fruit after fertilization.
• Produces seeds for new plants.
Conclusion
Flowers are not only beautiful but also play a key role in the life cycle of plants. They help in
reproduction, which ensures the continuation of plant species on Earth.
