Protection for Frog Eggs
Frog eggs are typically laid in water, and their protection is crucial for the survival of the developing embryos. The correct answer to the question about what provides this protection is option 'B': a layer of jelly.
Structure and Composition
- Frog eggs are surrounded by a gelatinous layer, commonly referred to as jelly.
- This jelly layer is composed of water and proteins, which serve multiple protective functions.
Functions of the Jelly Layer
- Physical Barrier: The jelly provides a soft yet firm shield against physical disturbances and predators. It helps to absorb shocks, protecting the delicate eggs inside.
- Hydration: The jelly is primarily composed of water, which helps keep the eggs hydrated. This is vital for their development, as the embryos need a moist environment to grow.
- Chemical Defense: The jelly can contain chemicals that deter predators and parasites, making it less appealing to potential threats.
- Oxygen Supply: The gelatinous layer allows for gas exchange, ensuring that the developing embryos receive enough oxygen while still being protected.
Conclusion
In summary, the jelly layer around frog eggs serves as a crucial protective mechanism that ensures the survival and development of the embryos. Its physical, chemical, and biological properties make it an essential feature of amphibian reproduction in aquatic environments.
