FAQs on Detailed Overview: Sexual Reproduction in Flowering Plants - 1 Video Lecture - Biology for JAMB
| 1. What is sexual reproduction in flowering plants? |  |
Ans. Sexual reproduction in flowering plants refers to the process by which plants produce offspring through the fusion of male and female gametes. It involves the transfer of pollen from the male reproductive organ (stamen) to the female reproductive organ (pistil) in order to facilitate fertilization and the production of seeds.
| 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 organ (anther) are transferred to the female reproductive organ (stigma) of the same or a different flower. This can be achieved through various means, such as wind, water, insects, or other animals.
| 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 by producing offspring with unique combinations of genes from both parents. This genetic variability enhances the plants' ability to adapt and survive in changing environments. Additionally, sexual reproduction allows for the exchange of beneficial traits between different individuals, leading to the evolution of more robust and adaptable plant populations.
| 4. What are the different types of sexual reproduction in flowering plants? | |
Ans. There are two main types of sexual reproduction in flowering plants: self-pollination and cross-pollination. Self-pollination occurs when pollen from the same flower or plant is transferred to the stigma of the same flower or plant. Cross-pollination, on the other hand, involves the transfer of pollen from one flower or plant to the stigma of a different flower or plant.
| 5. How does sexual reproduction contribute to the diversity of flowering plants? | |
Ans. Sexual reproduction plays a crucial role in generating diversity among flowering plants. By combining genetic material from two different parent plants, sexual reproduction produces offspring with unique traits and characteristics. This genetic diversity enables plants to adapt to various environmental conditions, resist diseases, and respond to changes in their surroundings. It also provides the basis for natural selection and evolution within plant populations.
