FAQs on Parts of a Flower - Getting to know Plants Video Lecture - Class 6

1. What are the different parts of a flower?
Ans. The different parts of a flower are the petals, sepals, stamens, and pistils. Petals are usually colorful and attract pollinators, sepals protect the flower bud, stamens are the male reproductive parts that produce pollen, and pistils are the female reproductive parts that receive pollen and produce seeds.
2. How do petals and sepals differ from each other?
Ans. Petals and sepals are both floral organs, but they have different functions. Petals are usually colorful and fragrant, attracting pollinators like bees and butterflies. They also play a role in protecting the reproductive parts of the flower. On the other hand, sepals are usually green and protect the flower bud before it blooms. They often resemble small leaves and help in supporting and enclosing the developing flower.
3. What is the role of stamens in a flower?
Ans. Stamens are the male reproductive parts of a flower. They consist of a long filament and an anther at the tip. The anther produces pollen grains, which contain the male gametes or sperm cells. When a pollinator, such as a bee, lands on the flower, the pollen sticks to its body and is transferred to another flower, allowing pollination to occur. In this way, stamens play a crucial role in the fertilization process of plants.
4. How do pistils contribute to the reproduction of a flower?
Ans. Pistils are the female reproductive parts of a flower. They consist of three main parts: the stigma, style, and ovary. The stigma is the sticky part at the top of the pistil that receives pollen grains. The style is a long tube that connects the stigma to the ovary. The ovary contains ovules, which are the female gametes or egg cells. When pollen grains land on the stigma, they travel down the style to reach the ovary and fertilize the ovules. This fertilization process leads to the formation of seeds.
5. How are flowers essential for the survival of plants?
Ans. Flowers play a critical role in the reproduction and survival of plants. They attract pollinators, such as insects, birds, and bats, with their bright colors, fragrances, and nectar. When these pollinators visit the flowers to feed on nectar, they unintentionally transfer pollen from the stamens to the pistils, allowing fertilization to occur. Fertilization leads to the production of seeds, which can then grow into new plants. Additionally, flowers also help in the dispersal of seeds through various mechanisms, ensuring the propagation and survival of plant species.
