Internal Or External Fertilization Quiz - Quiz

For the students of biology, we have brought the internal and external fertilization quiz. Do you know the difference between the two? Internal fertilization happens when the sperm fertilizes the egg inside the female. On the other hand, external fertilization is known as a type of reproduction that causes the sperm of a male creature to fertilize the egg of a female organism not inside but outside the female's body. To learn more, play this quiz.


Questions and Answers
  • 1. 

    Which of these is a method of internal fertilization?

    • A.

      Oviparity

    • B.

      Ovoviviparity

    • C.

      Viviparity

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    All of the options listed (oviparity, ovoviviparity, and viviparity) are methods of internal fertilization. Oviparity refers to the laying of fertilized eggs that develop outside the mother's body, such as in birds or reptiles. Ovoviviparity is the retention of fertilized eggs inside the mother's body until they hatch, as seen in some species of fish or insects. Viviparity is the development of embryos inside the mother's body, with the live birth of fully formed young, as seen in mammals. Therefore, all of these options involve internal fertilization.

    Rate this question:

  • 2. 

    In this method, the fertilized eggs are laid outside the mother's body. The egg gets nourishment from the yolk.

    • A.

      Viviparity

    • B.

      Oviparity

    • C.

      Ovoviviparity

    • D.

      None of these

    Correct Answer
    B. Oviparity
    Explanation
    Oviparity is the correct answer because it refers to the reproductive method where fertilized eggs are laid outside the mother's body. In this process, the egg obtains nourishment from the yolk. This is different from viviparity, where the embryo develops inside the mother's body and obtains nourishment directly from the mother, and ovoviviparity, where the embryo develops inside the mother's body but obtains nourishment from the yolk. None of these options fit the description given in the question.

    Rate this question:

  • 3. 

    In this method, the fertilized eggs get retained in the female, and the embryo gets nourishment from the yolk. At the time they hatch, the young ones are fully developed.

    • A.

      Ovoviviparity

    • B.

      Oviparity

    • C.

      Viviparity

    • D.

      None of these

    Correct Answer
    A. Ovoviviparity
    Explanation
    Ovoviviparity is the correct answer because it describes the reproductive method where fertilized eggs are retained inside the female and the embryo obtains nourishment from the yolk. The young ones are fully developed at the time of hatching. This term is used to differentiate it from oviparity, where eggs are laid and develop outside the female's body, and viviparity, where the embryo develops inside the female and is nourished by the mother's body.

    Rate this question:

  • 4. 

    Which of these is oviparous?

    • A.

      Fish

    • B.

      Amphibians

    • C.

      Reptiles

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    All of these options (fish, amphibians, and reptiles) are oviparous, meaning they lay eggs to reproduce. Fish, such as salmon or goldfish, lay eggs in water. Amphibians, like frogs or salamanders, lay eggs in water as well. Reptiles, including snakes, turtles, and crocodiles, lay eggs on land. Therefore, all of these animals are oviparous, making the answer "All of these" correct.

    Rate this question:

  • 5. 

    In this method, the young one develops inside the mother and gets nourishment through the placenta.

    • A.

      Ovoviviparity

    • B.

      Oviparity

    • C.

      Viviparity

    • D.

      None of these

    Correct Answer
    C. Viviparity
    Explanation
    Viviparity refers to the reproductive method in which the young one develops inside the mother and receives nourishment through the placenta. This process involves live birth, as opposed to oviparity where the eggs are laid outside the mother's body. Therefore, viviparity is the correct answer as it accurately describes the given explanation.

    Rate this question:

  • 6. 

    Most mammals are

    • A.

      Oviparous

    • B.

      Viviparous

    • C.

      Ovoviviparous

    • D.

      None of these

    Correct Answer
    B. Viviparous
    Explanation
    Viviparous means giving birth to live young rather than laying eggs. This is the correct answer because most mammals, including humans, give birth to live young. Oviparous refers to animals that lay eggs, such as birds and reptiles. Ovoviviparous refers to animals that produce eggs that hatch inside the body, and then give birth to live young, such as some species of sharks. None of these options would be correct for most mammals.

    Rate this question:

  • 7. 

    What type of fertilization do humans have?

    • A.

      External fertilization

    • B.

      Internal fertilization

    • C.

      Both

    • D.

      None

    Correct Answer
    B. Internal fertilization
    Explanation
    Humans have internal fertilization, which means that the fertilization of the egg by sperm takes place inside the body of the female. This is in contrast to external fertilization, where the sperm and egg meet outside of the body, such as in aquatic organisms. Internal fertilization allows for greater protection and control over the development of the embryo, as it occurs within the female's reproductive system.

    Rate this question:

  • 8. 

    Fertilization occurs _________ in terrestrial development.

    • A.

      Inside female body

    • B.

      Outside female body

    • C.

      Inside male body

    • D.

      Inside water

    Correct Answer
    A. Inside female body
    Explanation
    Fertilization occurs inside the female body during terrestrial development because in most terrestrial animals, including humans, the female reproductive system is equipped to receive and nurture the sperm. This allows for the fusion of the sperm and egg, leading to fertilization and the subsequent development of the embryo inside the female's reproductive organs.

    Rate this question:

  • 9. 

    What is the term for male sex cells?

    • A.

      Sperm

    • B.

      Egg

    • C.

      Pupa

    • D.

      Pupil

    Correct Answer
    A. Sperm
    Explanation
    The term for male sex cells is sperm. Sperm is the reproductive cell that is produced by males and is necessary for fertilization to occur. Sperm cells are typically smaller than female sex cells (eggs) and have a whip-like tail that helps them swim towards the egg for fertilization.

    Rate this question:

  • 10. 

    External Fertilization mostly takes place in

    • A.

      Fish

    • B.

      Amphibians

    • C.

      Both

    • D.

      None

    Correct Answer
    C. Both
    Explanation
    External fertilization mostly takes place in both fish and amphibians. In external fertilization, the process of fertilization occurs outside the body of the female organism. This is common in aquatic species like fish and amphibians, where the female releases eggs into the water and the male releases sperm to fertilize them externally. This method allows for a large number of eggs to be fertilized simultaneously, increasing the chances of successful reproduction.
