FAQs on Parts of Flower Video Lecture - NEET
| 1. What are the different parts of a flower? |  |
Ans. The different parts of a flower include the petals, sepals, stamen, pistil, and receptacle. Petals are the colorful and often scented parts of the flower that attract pollinators. Sepals are the leaf-like structures that protect the flower bud. The stamen is the male reproductive part, consisting of the filament and anther, which produces pollen. The pistil is the female reproductive part, consisting of the stigma, style, and ovary, which contains the ovules. The receptacle is the base of the flower where all the other parts are attached.
| 2. What is the role of petals in a flower? | |
Ans. The petals of a flower serve several important roles. They are often brightly colored and scented to attract pollinators, such as bees, butterflies, or birds. The petals help in the reproduction of the flower by attracting these pollinators to transfer pollen from the stamen to the pistil. Additionally, the petals also protect the reproductive structures of the flower, such as the stamen and pistil, from external damage.
| 3. How does the stamen contribute to flower reproduction? | |
Ans. The stamen is the male reproductive part of the flower. It consists of the filament, which holds up the anther. The anther contains pollen grains, which are the male gametes. When a pollinator comes in contact with the anther, the pollen grains can stick to its body. The pollinator then carries the pollen to another flower's stigma, where it can fertilize the ovules in the ovary, leading to seed formation and fruit development.
| 4. What is the significance of the pistil in flower reproduction? | |
Ans. The pistil is the female reproductive part of the flower. It consists of three main parts: the stigma, style, and ovary. The stigma is the sticky surface at the top of the pistil, which receives pollen grains. The style is a slender tube that connects the stigma to the ovary. The ovary contains the ovules, which are the female gametes. After pollen grains land on the stigma, they travel down the style to reach the ovary, where fertilization occurs, leading to the development of seeds and fruits.
| 5. How does the receptacle support the flower? | |
Ans. The receptacle is the base of the flower where all the other parts are attached. It provides support and stability to the flower, holding the petals, sepals, stamen, and pistil in place. The receptacle also plays a role in nourishing the flower, as it connects to the stem and allows nutrients and water to reach the flower's various parts. Additionally, the receptacle may also serve as a site for the development of the fruit after fertilization.
