Reproduction of Animals

  • Reproduction is the process by which animals have babies or offspring. 
  • It involves the coming together of a male and a female to create offspring through mating, a process known as sexual reproduction.

Fertilisation

  • Fertilisation occurs during sexual reproduction when a sperm from the male combines with an egg from the female. This process is crucial for the formation of offspring.
  • Examples of Egg-Laying Animals:
    • Fish
    • Reptiles, like snakes
    • Birds
    • Amphibians, like frogs
  • Some animals, such as frogs, lay numerous eggs as not all of them will mature into adults. For instance, a single female frog can lay thousands of eggs.
  • In mammals, including humans, after sexual reproduction, the female nurtures the baby or babies within her body until they are sufficiently developed to be born.

FAQs on How animals reproduce - Year 5 Science

1. How do animals reproduce?
Ans. Animals reproduce through a process called fertilisation, where a male gamete (sperm) fertilises a female gamete (egg) to form a zygote, which develops into a new individual.
2. What is the role of fertilisation in animal reproduction?
Ans. Fertilisation is the key process in animal reproduction where genetic material from both parents combines to create a unique individual with a combination of traits from each parent.
3. Can all animals reproduce sexually through fertilisation?
Ans. No, not all animals reproduce sexually through fertilisation. Some animals, like certain species of worms and insects, can reproduce asexually through processes such as budding or fragmentation.
4. How does fertilisation occur in different animal species?
Ans. Fertilisation can occur internally or externally in different animal species. Internal fertilisation happens inside the female's body, while external fertilisation occurs outside the body, typically in water for aquatic animals.
5. What are some examples of animals that reproduce through fertilisation?
Ans. Examples of animals that reproduce through fertilisation include mammals, birds, reptiles, amphibians, and many species of fish and invertebrates.
