Understanding External Fertilisation
External fertilisation is a reproductive strategy commonly found in aquatic organisms, such as fish and amphibians. This process involves the union of sperm and egg outside the bodies of the parents.
Key Characteristics of External Fertilisation:
- Sperms Swim Towards Eggs: In external fertilisation, male organisms release sperm into the water, where they swim in search of eggs released by female organisms. This movement is crucial for successful fertilisation.
- Aquatic Environment: The presence of water is essential for this process. It facilitates the movement of sperm and protects the gametes from desiccation.
- Mass Spawning: Many aquatic species engage in mass spawning, where multiple individuals release gametes simultaneously. This increases the chances of successful fertilisation as countless sperm are present in the water.
Contrast with Internal Fertilisation:
- Internal Fertilisation: In contrast, internal fertilisation occurs within the female’s body. Sperm is deposited inside the reproductive tract, leading to fertilisation without the need for an aquatic medium.
- Reproductive Strategies: While external fertilisation is efficient for species in water, internal fertilisation offers protection for developing embryos, which is advantageous in terrestrial environments.
Conclusion:
In summary, the correct answer to the question is option 'A' - external fertilisation. This process relies on the swimming capability of sperm in water to reach and fertilise the eggs, highlighting the adaptations of aquatic organisms to their environments.
