FAQs on Structure of Flower Video Lecture - NEET
| 1. What is the structure of a flower? |  |
Ans. A flower typically consists of four main parts: the sepals, petals, stamens, and pistil. The sepals are the outermost part of the flower and often protect the bud before it blooms. Petals are usually colorful and attract pollinators. Stamens are the male reproductive organs that produce pollen, while the pistil is the female reproductive organ that contains the ovary, style, and stigma.
| 2. How are flowers important for plant reproduction? | |
Ans. Flowers play a crucial role in plant reproduction as they facilitate the process of pollination. When pollinators, such as bees or butterflies, visit flowers to collect nectar or pollen, they inadvertently transfer pollen from the stamens to the pistil. This transfer of pollen allows for fertilization and the production of seeds, ensuring the continuation of the plant species.
| 3. What is the function of sepals in a flower? | |
Ans. Sepals are the outermost part of a flower and perform several functions. They primarily protect the developing bud before it opens. Additionally, sepals can also help attract pollinators by providing visual cues or acting as landing platforms. In some flowers, sepals may remain attached even after the petals have fallen off, providing protection for the developing fruit.
| 4. How do stamens contribute to flower reproduction? | |
Ans. Stamens are the male reproductive organs of a flower and play a crucial role in flower reproduction. They consist of a filament and an anther. The anther produces pollen, which contains the male gametes. When pollinators come into contact with the anthers, they collect pollen on their bodies. This pollen is then transferred to the stigma of another flower, allowing for fertilization to occur.
| 5. What is the function of the pistil in a flower? | |
Ans. The pistil is the female reproductive organ of a flower. It consists of three main parts: the stigma, style, and ovary. The stigma is the sticky, receptive surface that captures pollen. The style connects the stigma to the ovary, which contains the ovules. After pollination, the pollen grain travels down the style and fertilizes the ovules, leading to the formation of seeds within the ovary.
