Animal Reproduction Questions and Answers

  • 1. 

    What is reproduction?

    • A.

      When parents makes offspring

    • B.

      When offspring makes adults

    • C.

      When offspring is an exact copy of its parent

    Correct Answer
    A. When parents makes offspring
    Explanation
    Reproduction refers to the process in which parents produce offspring. It involves the transfer of genetic material from the parents to the offspring, resulting in the creation of new individuals. This can occur through sexual reproduction, where genetic material from two parents combines to form a unique offspring, or through asexual reproduction, where a single parent produces genetically identical offspring. In both cases, the main concept is that reproduction involves the creation of new individuals by parents.

    Some simple invertebrates reproduce by budding. What is budding?

    • A.

      When an animal develops from a part of its parent

    • B.

      When a bud forms on the adult's body and develops into a new animal

    • C.

      When a leaf buds into a flower

    Correct Answer
    B. When a bud forms on the adult's body and develops into a new animal
    Explanation
    Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the body of the parent organism. This bud eventually detaches from the parent and develops into a new, independent individual. This process is commonly observed in simple invertebrates where the bud grows and matures into a fully functional organism.

  • 3. 

    Sea stars and other echinoderms can reproduce by regeneration. What is regeneration?

    • A.

      An exact copy of its parent

    • B.

      A whole animal develops from a part of the original animal

    • C.

      When an animal develops from an egg

    • D.

      All of the above

    Correct Answer
    B. A whole animal develops from a part of the original animal
    Explanation
    Regeneration refers to the process in which a whole animal develops from a part of the original animal. In other words, when a part of an organism is damaged or lost, it has the ability to grow back and form a complete and functional organism. This ability is observed in sea stars and other echinoderms, allowing them to regenerate lost limbs or even their entire body.

    Rate this question:

  • 4. 

    Why do animals reproduce?

    • A.

      To make new animals

    • B.

      Obligation to the species

    • C.

      To get rid of unhealthy animals

    Correct Answer
    A. To make new animals
    Explanation
    Animals reproduce in order to create new individuals of their species. Reproduction is a fundamental biological process that ensures the continuation of a species over time. By producing offspring, animals pass on their genetic material and contribute to the genetic diversity of their population. This allows for adaptation to changing environments and increases the chances of survival for the species as a whole. Reproduction also plays a role in maintaining the balance of ecosystems by providing a constant supply of individuals to replace those that die.

    Rate this question:

  • 5. 

    Which kind of animal would a bird produce?

    • A.

      Owl

    • B.

      Bird

    • C.

      Monkey

    • D.

      Butterfly

    Correct Answer
    B. Bird
    Explanation
    A bird would produce another bird because birds reproduce by laying eggs, which hatch into baby birds. Birds belong to the class Aves, and they have specific characteristics and adaptations that allow them to fly and live in various habitats. Therefore, it is logical to conclude that a bird would produce another bird.

    Rate this question:

  • 6. 

    How many parents are involved in budding and regeneration?

    • A.

      0

    • B.

      1

    • C.

      2

    • D.

      3

    Correct Answer
    B. 1
    Explanation
    In budding and regeneration, only one parent is involved. This is because budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. The new organism is genetically identical to the parent and therefore only one parent is needed for this process. Similarly, in regeneration, the ability of an organism to regrow lost or damaged body parts, again only one parent is involved in the process.

    Rate this question:

  • 7. 

    Both budding and regeneration produce clones. What is a clone?

    • A.

      An exact copy of its parent

    • B.

      Similar traits of its parent

    • C.

      Exact opposite of its parent

    Correct Answer
    A. An exact copy of its parent
    Explanation
    A clone refers to an organism or cell that is genetically identical to its parent. It is an exact copy of its parent in terms of its genetic makeup and traits. Cloning can occur through budding, where a new organism grows from a part of the parent, or through regeneration, where a whole new organism is formed from a fragment of the parent's body. In both cases, the resulting clone will possess the same genetic information and characteristics as its parent.

    Rate this question:

  • 8. 

    When traits are passed from parent to offspring, those traits are ______________ .

    • A.

      Charateristics

    • B.

      Inherited

    • C.

      Similar

    • D.

      Different

    Correct Answer
    B. Inherited
    Explanation
    Traits that are passed from parent to offspring are inherited. This means that the offspring will possess similar characteristics to their parents due to the transmission of genetic information.

  • 9. 

    Another kind of reproduction requires cells from two parents. What is the female cell called?

    • A.

      Sperm

    • B.

      Fertilization

    • C.

      Egg

    Correct Answer
    C. Egg
    Explanation
    In sexual reproduction, the female cell is called an egg. It is the larger of the two types of reproductive cells and is produced by the female reproductive system. During fertilization, the egg is fertilized by a sperm cell from the male, resulting in the formation of a zygote. The zygote then develops into a new individual.

    Rate this question:

  • 10. 

    The male cell is called the sperm. When an egg and a sperm join, what happens?

    • A.

      Fertilization

    • B.

      Regeneration

    • C.

      Rebirth

    • D.

      Budding

    Correct Answer
    A. Fertilization
    Explanation
    Fertilization is the process in which the male sperm cell and the female egg cell combine to form a fertilized egg, also known as a zygote. This is a crucial step in sexual reproduction, as it leads to the development of a new organism. During fertilization, the genetic material from both the sperm and the egg combine, resulting in a unique combination of genes that will determine the traits and characteristics of the offspring.

    Rate this question:

  • 11. 

    Which of these animals reproduce by external fertilisation?

    • A.

      Camels

    • B.

      Cod

    • C.

      Parrots

    • D.

      Bats

    Correct Answer
    B. Cod
    Explanation
    Cod reproduce by external fertilization. This means that the female releases her eggs into the water and the male then releases his sperm to fertilize the eggs externally. This process occurs outside of the body, typically in the open water. Other animals, such as camels, parrots, and bats, reproduce through internal fertilization where the sperm fertilizes the eggs inside the female's body.

    Rate this question:

  • 12. 

    What part of the female reproductive system produces the eggs (ova)?

    • A.

      Oviducts

    • B.

      Uterus

    • C.

      Ovary

    • D.

      Vagina

    Correct Answer
    C. Ovary
    Explanation
    The ovaries are the part of the female reproductive system that produces the eggs (ova). These almond-shaped organs are located on either side of the uterus and are responsible for the production and release of eggs during the menstrual cycle. The ovaries also produce hormones such as estrogen and progesterone, which play a crucial role in regulating the reproductive system and maintaining pregnancy.

    Rate this question:

  • 13. 

    What term do we use to describe a sperm cell fusing with an egg cell?

    • A.

      Combination

    • B.

      Reproduction

    • C.

      Fertilization

    • D.

      Interaction

    Correct Answer
    C. Fertilization
    Explanation
    Fertilization is the correct answer because it refers to the process in which a sperm cell combines with an egg cell, resulting in the formation of a zygote. This process is essential for sexual reproduction in many organisms, including humans.

    Rate this question:

  • 14. 

    How are sperm cells adapted for their function?

    • A.

      Not having a nucleus to save energy

    • B.

      Having sharp teeth to cut into the egg cell

    • C.

      Being streamlined to be able to swim faster

    • D.

      None of the above

    Correct Answer
    C. Being streamlined to be able to swim faster
    Explanation
    Sperm cells are adapted for their function by being streamlined to be able to swim faster. This adaptation allows them to move efficiently through the female reproductive tract and reach the egg for fertilization. The streamlined shape reduces drag and resistance, enabling sperm to navigate through the fluid environment more effectively. This adaptation increases the chances of successful fertilization by ensuring that sperm can reach the egg in a timely manner.

    Rate this question:

  • 15. 

    Why are egg cells larger than sperm cells?

    • A.

      Egg cells have more cells in them

    • B.

      Egg cells have a food store to help growth after fertilization

    • C.

      Egg cells have thicker cell membranes

    • D.

      Egg cells have larger nuclei

    Correct Answer
    B. Egg cells have a food store to help growth after fertilization
    Explanation
    Egg cells are larger than sperm cells because they have a food store to support the growth and development of the embryo after fertilization. This food store, known as yolk, provides essential nutrients for the early stages of embryonic development. In contrast, sperm cells are smaller and more streamlined, as their main function is to deliver the genetic material to the egg for fertilization. The presence of a food store in egg cells allows them to provide the necessary resources for the developing embryo until it can establish its own means of obtaining nutrients.

    Rate this question:

  • 16. 

    Which organism does not produce an external egg as part of its life cycle?

    • A.

      Dog

    • B.

      Parrot

    • C.

      Turtle

    • D.

      Stick insect

    Correct Answer
    A. Dog
    Explanation
    Dogs do not produce external eggs as part of their life cycle. They give birth to live young ones instead. Unlike turtles, parrots, and stick insects, which lay eggs externally, dogs have internal fertilization and give birth to fully developed puppies.

    Rate this question:

  • 17. 

    Why do many organisms produce thousands of offspring?

    • A.

      To increase the chance of some surviving

    • B.

      To make sure that there are lots of brothers and sister

    • C.

      To provide food for predators

    • D.

      Egg production requires very little energy

    Correct Answer
    A. To increase the chance of some surviving
    Explanation
    Many organisms produce thousands of offspring to increase the chance of some surviving. By producing a large number of offspring, there is a higher likelihood that at least a few will survive and pass on their genes to the next generation. This strategy helps to ensure the continuation of the species, as those individuals with traits that are better suited to their environment have a higher chance of survival and reproduction.

    Rate this question:

  • 18. 

    What is the female gamete called?

    • A.

      Cervix

    • B.

      Sperm

    • C.

      Ovary

    • D.

      Ovum

    Correct Answer
    D. Ovum
    Explanation
    The female gamete is called an ovum. This is the reproductive cell produced by the ovaries, which is necessary for fertilization to occur. The cervix is a part of the female reproductive system but it is not the female gamete. Sperm is the male gamete.

    Rate this question:

  • 19. 

    How is the sperm adapted to perform its function?

    • A.

      It has a tail to help it swim.

    • B.

      It has a cell membrane to enable substances to diffuse into the cell

    • C.

      It has a nucleus containing genetic material

    • D.

      It has cytoplasm

    Correct Answer
    A. It has a tail to help it swim.
    Explanation
    The sperm is adapted to perform its function through its tail, which allows it to swim. This adaptation enables the sperm to move towards the egg for fertilization. The tail, also known as the flagellum, propels the sperm forward, increasing its chances of reaching and penetrating the egg. This adaptation is crucial for the sperm's ability to successfully fulfill its reproductive role.

    Rate this question:

  • 20. 

    Where is the ovum produced?

    • A.

      Uterus

    • B.

      Cervix

    • C.

      Vagina

    • D.

      Ovary

    Correct Answer
    D. Ovary
    Explanation
    The ovum, also known as the egg, is produced in the ovary. The ovary is a reproductive organ in females that is responsible for producing and releasing eggs during the menstrual cycle. Once the ovum is released from the ovary, it travels through the fallopian tube towards the uterus, where it may be fertilized by sperm if conception occurs. Therefore, the correct answer is ovary.

  • 21. 

    What is metamorphosis?

    • A.

      When animals change into other animals

    • B.

      When animals reproduce

    • C.

      A series of very different body forms

    Correct Answer
    C. A series of very different body forms
    Explanation
    Metamorphosis refers to a process where an animal undergoes a series of distinct and significant changes in its body form as it progresses through different life stages. This transformation can involve changes in physical structures, such as the development of wings or legs, or even alterations in the overall body shape. This answer accurately captures the essence of metamorphosis, highlighting the sequential and distinct nature of the body form changes that occur during this process.

    Rate this question:

  • 22. 

    Which animal grows through metamorphosis?

    • A.

      Polar bear

    • B.

      Butterfly

    • C.

      Dog

    • D.

      All of the above

    Correct Answer
    B. Butterfly
    Explanation
    Butterflies grow through metamorphosis, which is a process where they undergo a complete transformation from egg to larva (caterpillar), then pupa (chrysalis), and finally emerge as an adult butterfly. This process involves significant changes in their body structure, behavior, and appearance. While polar bears and dogs also go through growth and development, they do not undergo metamorphosis like butterflies do.

    Rate this question:

  • 23. 

    True or False? Incomplete metamorphosis is when each body form is separate, but not that different from the one before.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Incomplete metamorphosis is a type of metamorphosis in which the insect undergoes three stages: egg, nymph, and adult. In this process, the nymphs look similar to the adults but lack wings and reproductive organs. Therefore, each body form is separate but not drastically different from the previous one. Hence, the statement is true.

    Rate this question:

  • 24. 

    Which of the following goes through incomplete metamorphosis?

    • A.

      Grasshoppers

    • B.

      Termites

    • C.

      Damsel flies

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    All of the above options, grasshoppers, termites, and damselflies, go through incomplete metamorphosis. In incomplete metamorphosis, the insect goes through three stages: egg, nymph, and adult. The nymph stage resembles the adult form but lacks wings and reproductive organs. As the nymph grows, it molts several times until it reaches its final adult form. Grasshoppers, termites, and damselflies all follow this pattern of development, making the answer "all of the above" correct.

    Rate this question:

  • 25. 

    When an insect goes through incomplete metamorphosis, it molts. What is molting?

    • A.

      When an insect gets too large for its exoskeleton

    • B.

      When an insect reproduces

    • C.

      When an insect sheds its exoskeleton and grows a new one

    • D.

      A and C

    Correct Answer
    D. A and C
    Explanation
    When an insect goes through incomplete metamorphosis, it molts. Molting refers to the process where an insect sheds its exoskeleton, which has become too small or restrictive, and grows a new one. This allows the insect to accommodate its increasing size and continue its growth and development. Both options A and C correctly describe molting as the shedding of the exoskeleton and the growth of a new one.

    Rate this question:

  • 26. 

    Butterflies go through complete metamorphosis. What does this mean?

    • A.

      Each body form is different

    • B.

      Each life stage is different

    • C.

      The butterfly changes into larva

    • D.

      The egg changes into pupa

    Correct Answer
    B. Each life stage is different
    Explanation
    Complete metamorphosis refers to a type of development that involves distinct and drastic changes in the life stages of an organism. In the case of butterflies, they undergo four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult butterfly. Each stage is different in terms of appearance, behavior, and habitat. This process allows butterflies to adapt to different environments and maximize their chances of survival and reproduction.

    Rate this question:

  • 27. 

    Name the stages in order of the complete metamorphosis of a butterfly.

    • A.

      Egg, larva, pupa, adult

    • B.

      Egg, pupa, larva, adult

    • C.

      Adult, egg, larva, pupa

    • D.

      Adult, egg, pupa, larva

    Correct Answer
    A. Egg, larva, pupa, adult
    Explanation
    The correct order of the stages in the complete metamorphosis of a butterfly is egg, larva, pupa, and adult. This is because butterflies start their life cycle as eggs, which then hatch into larvae or caterpillars. The larvae go through several molting stages, growing in size and eventually forming a pupa or chrysalis. Inside the pupa, the caterpillar undergoes a transformation and emerges as an adult butterfly.

    Rate this question:

  • 28. 

    What happens in the pupa stage

    • A.

      It begins to eat the leaf

    • B.

      It becomes an adult

    • C.

      The larva develops adult tissues and organs

    Correct Answer
    C. The larva develops adult tissues and organs
    Explanation
    During the pupa stage, the larva undergoes a process called metamorphosis. In this stage, the larva develops into an adult by transforming its tissues and organs. This transformation involves the breakdown of larval structures and the formation of new adult structures. The pupa stage is a crucial period where the larva undergoes significant changes to prepare for its adult life. It is a time of development and growth, leading to the emergence of the fully formed adult organism.

    Rate this question:

  • 29. 

    Which of the following does NOT go through complete metamorphosis?

    • A.

      Beetles

    • B.

      Flies

    • C.

      Butterflies

    • D.

      Grasshoppers

    Correct Answer
    D. Grasshoppers
    Explanation
    Grasshoppers do not go through complete metamorphosis. They undergo incomplete metamorphosis instead, which means they have three life stages: egg, nymph, and adult. In incomplete metamorphosis, the nymphs resemble miniature versions of the adults and gradually develop into adults without a pupal stage. In contrast, beetles, flies, and butterflies all go through complete metamorphosis, which includes four distinct life stages: egg, larva, pupa, and adult.
