Full Question List & Answer Key

Prefer reading to quizzing? All 10 questions are listed below with the answer and explanation under each one.

1. Which hormone-producing organ in the male reproductive system generates sperm cells?

  1. Prostate gland
  2. Testis
  3. Seminal vesicle
  4. Scrotum
Show answer

Answer: B

The testes are responsible for producing male gametes (sperm) and testosterone.

2. Which method of asexual reproduction is utilized by bread mold (Mucor) to spread?

  1. Regeneration
  2. Spore formation
  3. Budding
  4. Binary fission
Show answer

Answer: B

Mucor produces light, microscopic spores inside sporangia that disperse through the air to colonize new food sources.

3. What is the correct biological sequence following successful fertilization in humans?

  1. Zygote → Embryo → Fetus → Baby
  2. Embryo → Zygote → Fetus → Baby
  3. Fetus → Embryo → Zygote → Baby
  4. Zygote → Fetus → Embryo → Baby
Show answer

Answer: A

Fertilization yields a single-celled zygote, which divides into an embryo, implants and grows into a fetus, and is delivered as a baby.

4. Which organ of a flower develops into a fruit after successful fertilization?

  1. Ovule
  2. Petal
  3. Ovary
  4. Stigma
Show answer

Answer: C

Following fertilization, the ovary matures into a fruit, while the ovules inside transform into seeds.

5. What primary protective role is served by the fluid contained inside the amniotic sac?

  1. Provides nutrients to the developing fetus
  2. Cushions the fetus against physical impacts and mechanical shocks
  3. Carries waste products out of the uterus
  4. Maintains hormonal balance during labor
Show answer

Answer: B

Amniotic fluid acts as a protective shock absorber guarding the developing fetus against external pressure or bumps.

6. What is the role of the cervix in the female human reproductive system?

  1. Produces ovum and progesterone
  2. Serves as the narrow entrance to the uterus and secretes mucus
  3. Site where fertilization takes place
  4. Holds the fetus using amniotic fluid
Show answer

Answer: B

The cervix is the lower, narrow neck of the uterus connecting it to the vagina.

7. What key advantage does cross-pollination offer over self-pollination in plants?

  1. Requires fewer pollinating insects
  2. Produces genetically identical offspring rapidly
  3. Yields seeds with higher genetic variation and better resistance
  4. Eliminates the need for water during growth
Show answer

Answer: C

Cross-pollination combines genetic material from two distinct parent plants, generating healthier seeds with greater genetic diversity.

8. Which of the following organisms reproduces asexually through binary fission?

  1. Hydra
  2. Mucor
  3. Amoeba
  4. Fern
Show answer

Answer: C

Amoeba is a unicellular organism that reproduces by splitting into two equal, identical daughter cells via binary fission.

9. What is the primary function of the placenta during pregnancy?

  1. Protects the fetus against mechanical shocks
  2. Facilitates exchange of nutrients, oxygen, and waste between mother and fetus
  3. Produces amniotic fluid to keep the fetus moist
  4. Directly mixes maternal and fetal blood for rapid transport
Show answer

Answer: B

The placenta allows essential nutrients and oxygen to pass from maternal blood to fetal blood while removing metabolic wastes, without mixing their blood streams directly.

10. Which structure connects the developing fetus directly to the placenta?

  1. Fallopian tube
  2. Amniotic sac
  3. Umbilical cord
  4. Cervix
Show answer

Answer: C

The umbilical cord contains fetal blood vessels that run between the fetus and the placenta.
