Explanation: Reproduction is the biological process by which new individuals of the same species are produced, ensuring the continuation of the species.
2. What is the function of the ovaries in the female reproductive system?
a) Production of eggs and hormones
b) Transport of sperm to the uterus
c) Fertilization of the egg
d) Secretion of milk
Answer: a) Production of eggs and hormones

3. How many modes of reproduction are there in animals?
a) One
b) Two
c) Three

Explanation: Animals reproduce primarily through two modes: sexual reproduction and asexual reproduction.
4. What is the objective of reproduction?
a) To maintain genetic diversity
b) To produce hormones
c) To regulate body temperature
d) To produce energy
Answer: a) To maintain genetic diversity
Explanation: The primary objective of reproduction is to produce offspring that inherit genetic material from both parents, thereby maintaining genetic diversity within a population.
5. What is the role of the uterus?
a) Production of eggs
b) Transport of sperm
c) Implantation and development of embryos
d) Hormone secretion
Answer: c) Implantation and development of embryos
Explanation: The uterus, or womb, is a hollow muscular organ in the female reproductive system where fertilized eggs (embryos) implant and develop into fetuses during pregnancy.
6. What is the function of testis?
a) Production of eggs
b) Transport of sperm
c) Production of sperm and hormones
d) Implantation of embryos
Answer: c) Production of sperm and hormones

Reproduction in lower and higher Animals MCQ with Answers PDF:
1. The number of nuclei present in a zygote is________
a. two
b. one
c. four
d. eight
Answer: a
Explanation: Ovum (female gamete) and sperm (male gamete) are both haploid (n) entities. The zygote is formed by fertilization. i.e. fusion of male and female gametes. Thus, in a zygote male and female gametes combine together to form a diploid (2n) zygote. Ovum(n) + Sperm(n) => Zygote (2n)
2. Which of these is the male reproductive organ in humans?
a. sperm
b. seminal fluid
c. testes
d. ovary
Answer: c
Explanation: The main male sex organs are the penis and the testicles (testes) which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female’s body; the fertilized ovum (zygote) develops into a fetus, which is later born as an infant.
3. Attachment of embryo to the wall of the uterus is known as_____________
a. fertilization
b. gestation
c. cleavage
d. implantation
Answer: d
Explanation: In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is called a blastocyst. It is by this adhesion that the embryo receives oxygen and nutrients from the mother to be able to grow.
4. Rupturing of follicles and discharge of ova is known as___________
a. capacitation
b. gestation
c. ovulation
d. copulation
Answer: c
Explanation: The rupturing of Graafian follicles to release the secondary oocyte (ovum) from the ovary is called ovulation. In other words, ovulation is the release of a mature egg from the ovary.
5. In the human female, the fertilized egg gets implanted in the uterus____________
a. After about 7 days of fertilization
b. After about 30 days of fertilization
c. After about two months of fertilization
d. After about 3 weeks of fertilization.
Answer: a
Explanation: The fertilized egg or zygote undergoes several divisions to form the embryo. It moves into the uterus within a period of 4-5 days. In the uterus, the embryo implants itself into the endometrial lining 7-8 days after fertilization. After implantation, it secretes a hormone called human chorionic gonadotrophin (hCG) which helps maintain the pregnancy. Thus, the correct answer is option a.
6. Test tube baby technique is called_________
a. In vivo fertilization
b. In situ fertilization
c. In vitro fertilization
d. Artificial insemination
Answer: c) In vitro fertilization
Explanation: In vitro fertilization (IVF) is a technique where fertilization occurs outside the body, typically in a laboratory setting, involving the combination of eggs and sperm in a controlled environment.
7. Presence of beard in boys is a____________
a. primary sex organ
b. secondary sexual character
c. secondary sex organ
d. primary sexual character.
Answer: b) secondary sexual character
Explanation: Secondary sexual characteristics are features that develop during puberty in humans and other animals that distinguish between the sexes but are not directly involved in reproduction. The presence of a beard in boys is an example of a secondary sexual characteristic.
