FAQs on Angiosperm Flower : Morphology of Flowering Plants Video Lecture - Class 11

1. What is the morphology of an angiosperm flower?
Ans. The morphology of an angiosperm flower refers to its physical structure and arrangement of different floral parts. It includes the sepals, petals, stamens, and pistils, which are arranged in a specific manner to attract pollinators and facilitate reproduction.
2. What is the role of sepals in an angiosperm flower?
Ans. Sepals are the outermost whorl of floral parts in an angiosperm flower. They are usually green in color and protect the developing flower bud. Sepals also play a role in attracting pollinators and provide support to the petals.
3. How are petals different from sepals in an angiosperm flower?
Ans. Petals are the second whorl of floral parts in an angiosperm flower, located inside the sepals. They are usually brightly colored and fragrant, serving the purpose of attracting pollinators towards the flower. Unlike sepals, petals are not involved in protecting the flower bud.
4. What are stamens and pistils in an angiosperm flower?
Ans. Stamens and pistils are the reproductive parts of an angiosperm flower. Stamens are male reproductive organs that consist of a filament and an anther, where pollen grains are produced. Pistils, on the other hand, are female reproductive organs that consist of a stigma, style, and ovary, where the ovules are located.
5. How does the structure of an angiosperm flower contribute to its reproductive success?
Ans. The structure of an angiosperm flower plays a crucial role in its reproductive success. The arrangement of floral parts helps in attracting specific pollinators, such as insects or birds, which aid in pollen transfer between flowers for fertilization. The presence of brightly colored petals and fragrances further enhance the flower's attractiveness to pollinators. Additionally, the location and structure of stamens and pistils ensure efficient pollen transfer and successful fertilization.
