Free Reproduction MCQs with Answers
1,220 Reproduction MCQs from Biology, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.

- A. Produces sperm
- B. Stores sperm
- C. Secretes testosterone
- D. Conducts urine and semen
Explanation: Structure 4 is the testis, responsible for sperm production and testosterone secretion.
Correct answer: Produces sperm- A. Transporting sperm to urethra
- B. Producing testosterone
- C. Secreting seminal fluid
- D. Storing sperm
Explanation: Seminal vesicle contributes fructose-rich fluid to semen for sperm nutrition.
Correct answer: Storing sperm- A. Site of sperm production
- B. Stores and matures sperm
- C. Transports sperm from epididymis to urethra
- D. Secretes seminal fluid
Explanation: The vas deferens is a muscular tube that carries sperm from the epididymis to the ejaculatory ducts and then to the urethra during…
Correct answer: Transports sperm from epididymis to urethra- A. Ovary - site of oogenesis and hormone secretion
- B. Fallopian tube - site of fertilization
- C. Uterus - implantation of embryo
- D. Cervix - opening of uterus
Explanation: Ovary produces ova and secretes estrogen and progesterone.
Correct answer: Ovary - site of oogenesis and hormone secretion- A. Transporting ovum from ovary to uterus
- B. Site of sperm production
- C. Implantation of zygote
- D. Menstrual blood storage
Explanation: Fallopian tube carries ovum and is the usual site of fertilization.
Correct answer: Transporting ovum from ovary to uterus- A. Uterus - site of embryo implantation and fetal development
- B. Ovary - produces ova
- C. Fallopian tube - site of fertilization
- D. Vagina - site of sperm deposition
Explanation: Uterus is the muscular organ that supports embryo and fetal growth.
Correct answer: Uterus - site of embryo implantation and fetal development- A. Cervix - narrow neck of uterus connecting to vagina
- B. Ovary - produces hormones
- C. Uterine tube - transports ovum
- D. Vagina - site of fertilization
Explanation: Cervix forms a canal between the uterus and vagina and acts as a barrier to pathogens.
Correct answer: Cervix - narrow neck of uterus connecting to vagina- A. Urethra - passage for urine and semen
- B. Vas deferens - transports sperm only
- C. Prostate - secretes testosterone
- D. Epididymis - sperm maturation
Explanation: The urethra serves as a dual-purpose tube for the excretion of urine and ejaculation of semen.
Correct answer: Urethra - passage for urine and semen- A. Transport the ovum from ovary to uterus
- B. Capture the ovulated egg from the ovary
- C. Site of fertilization
- D. Secrete estrogen
Explanation: The fimbriae are finger-like projections at the end of the fallopian tube that sweep the ovulated oocyte from the ovary into the tube for…
Correct answer: Capture the ovulated egg from the ovary- A. Mitosis
- B. Meiosis
- C. Sex hormones
- D. All (A), (B) and (C)
Explanation: Mitosis is the basis for asexual reproduction in many organisms. Asexual reproduction involves the production of offspring that are…
Correct answer: Mitosis- A. Organisms increases rapidly
- B. Organisms are morphologically alike
- C. Organisms are genetically alike
- D. All (A), (B) and (C)
Explanation: Asexual reproduction is often a quicker process than sexual reproduction because it does not involve the complexities of meiosis, the…
Correct answer: All (A), (B) and (C)- A. Genetically varied individuals are born
- B. Chances of survival increases
- C. Chances of evolution increases
- D. All (A), (B) and (C)
Explanation: Explanation for this question will be added soon!
Correct answer: All (A), (B) and (C)- A. Spores
- B. Vegetative propagation
- C. Apomixis
- D. All (A), (B) and (C)
Explanation: Explanation for this question will be added soon!
Correct answer: All (A), (B) and (C)- A. Cuttings
- B. Tissues culture
- C. Both (A) and (B)

Explanation: Yes, this is correct. Taking cuttings is a common method of artificial or human-assisted asexual reproduction in plants.
Correct answer: Both (A) and (B)- A. 500,000
- B. 50,000
- C. 80,000
- D. 200,000
Explanation: The number of spores produced by a single mushroom can vary depending on the species and environmental conditions.
Correct answer: 500,000- A. Sporulation
- B. Apomixis
- C. Vegetative propagation
- D. Cutting
Explanation: Perennating organs, which are structures that enable plants to survive adverse conditions and unfavorable seasons, are often associated…
Correct answer: Vegetative propagation- A. Pollen tube
- B. Leaf
- C. Ovule
- D. All of the choices are correct
Explanation: Apomixis is a form of asexual reproduction in plants where embryos are formed without the process of fertilization.
Correct answer: Ovule- A. 1 parent
- B. 2 parent
- C. Spores
- D. Vegetative parts
Explanation: Asexual reproduction differs from sexual reproduction in that it does not require 2 parent is a key distinction between asexual and sexual…
Correct answer: 2 parent- A. Variation
- B. Similarity between parents and offspring
- C. Same chromosomal number in offsprings
- D. All of the choices are incorrect
Explanation: Asexual reproduction typically produces offspring that are genetically identical or nearly identical to the parent organism, and as a…
