1. 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.

2. 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.

3. 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.

4. Which process describes the transfer of pollen grains from an anther to a sticky stigma?

  1. Fertilization
  2. Pollination
  3. Germination
  4. Implantation
Show answer

Answer: B

Pollination is the mechanical or biological transfer of pollen from the male anther to the female stigma.

5. 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.

6. 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.

7. What happens to the uterine lining during Days 1 to 5 if an egg is not fertilized?

  1. It thickens rapidly with extra blood vessels
  2. An egg implants into the tissue
  3. It breaks down and sheds through the vagina as menstruation
  4. It remains static awaiting sperm arrival
Show answer

Answer: C

In the absence of fertilization, estrogen and progesterone levels drop, causing the uterine wall lining to disintegrate and shed as menstrual flow.

8. Which form of asexual reproduction involves an outgrowth developing on the parent organism before detaching?

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

Answer: B

Budding involves the growth of a small protrusion (bud) on the parent body (such as in yeast or Hydra) that eventually detaches as a new organism.

9. 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.

10. Which flower structure comprises the male reproductive organ (stamen)?

  1. Stigma and Style
  2. Anther and Filament
  3. Ovary and Ovule
  4. Petal and Sepal
Show answer

Answer: B

The stamen is the male organ consisting of the anther (which produces pollen) and the supporting filament.
