FAQs on Internal Fertilization Video Lecture - Class 8
| 1. What is internal fertilization? |  |
Ans. Internal fertilization is the process by which fertilization of an egg occurs inside the body of a female organism. During internal fertilization, sperm is transferred directly into the female's reproductive tract, where it meets and fertilizes the egg.
| 2. Which organisms undergo internal fertilization? | |
Ans. Internal fertilization is common in various organisms such as mammals, reptiles, birds, and some species of insects. These organisms have evolved specialized reproductive organs and behaviors to facilitate internal fertilization.
| 3. How does internal fertilization differ from external fertilization? | |
Ans. Internal fertilization differs from external fertilization in that the fusion of sperm and egg occurs inside the female's body in internal fertilization, while in external fertilization, the fusion of sperm and egg occurs outside the body, typically in water.
| 4. What are the advantages of internal fertilization? | |
Ans. Internal fertilization offers several advantages. It increases the chances of successful fertilization as the sperm is protected from external conditions and has a higher chance of reaching the egg. It also allows for the development of offspring in a protected environment, reducing the risk of predation and providing parental care opportunities.
| 5. How does internal fertilization contribute to the diversity of species? | |
Ans. Internal fertilization has played a significant role in the evolution and diversification of species. It allows for the development of various reproductive strategies, such as specialized reproductive organs, courtship behaviors, and parental care. These adaptations have led to the emergence of diverse species with unique reproductive strategies and characteristics.
