FAQs on Overview: Sexual Reproduction in Flowering Plants Video Lecture - NEET
| 1. What is sexual reproduction in flowering plants? |  |
Ans. Sexual reproduction in flowering plants is a process where male and female reproductive structures come together to produce offspring. It involves the fusion of male gametes (pollen) with female gametes (ovules) to form seeds. This process enables genetic variation and the creation of new combinations of traits in offspring.
| 2. How do flowering plants reproduce sexually? | |
Ans. Flowering plants reproduce sexually through a process called pollination. Pollination occurs when pollen grains from the male reproductive structure (anther) are transferred to the female reproductive structure (stigma) of the same or a different flower. This can be achieved through various mechanisms like wind, water, or through the help of animals such as bees, butterflies, or birds.
| 3. What are the advantages of sexual reproduction in flowering plants? | |
Ans. Sexual reproduction in flowering plants offers several advantages. Firstly, it promotes genetic diversity as it involves the combination of genetic material from two different individuals. This increases the chances of offspring adapting to changing environmental conditions. Secondly, sexual reproduction allows for the formation of seeds, which are crucial for dispersal and survival of the species. Additionally, sexual reproduction helps in the repair of damaged DNA through recombination during the formation of gametes.
| 4. Can flowering plants reproduce asexually as well? | |
Ans. Yes, flowering plants have the ability to reproduce asexually as well. Asexual reproduction in plants involves the production of new individuals without the involvement of gametes or the fusion of genetic material. Common methods of asexual reproduction in flowering plants include vegetative propagation, where new plants are formed from stems, roots, or leaves, and apomixis, where seeds are produced without fertilization. However, sexual reproduction is the primary mode of reproduction in flowering plants.
| 5. How does sexual reproduction contribute to the evolution of flowering plants? | |
Ans. Sexual reproduction plays a significant role in the evolution of flowering plants. By introducing genetic variation through the combination of genetic material from two parents, sexual reproduction allows for the emergence of new traits and adaptations. This genetic diversity increases the chances of survival and successful reproduction in changing environments. It also enables plants to respond to natural selection and evolve over time, leading to the diversification and evolution of different species of flowering plants.
