Show answer & explanation
Correct answer: A — Ovum
Oogenesis is the process of egg cell formation, resulting in the production of ova (eggs).
Q2. Which stage of early embryonic development results in the formation of the blastocyst in human reproduction?
Show answer & explanation
Correct answer: C — Blastulation stage
The process where the morula develops into a fluid-filled structure called the blastocyst, which is capable of implantation, is termed the blastulation stage.
Q3. Which hormone is primarily responsible for regulating the menstrual cycle and the uterine lining changes?
Show answer & explanation
Correct answer: B — Estrogen
Estrogen and Progesterone levels fluctuate cyclically to regulate the menstrual cycle and the preparation of the uterus lining.
Q4. In flowering plants, the primary function of the endosperm is to provide food for the developing embryo. Which of the following accurately describes the relationship between the endosperm and the embryo during seed development?
Show answer & explanation
Correct answer: C — The endosperm stores the food reserves necessary for the growth of the developing embryo.
The endosperm is the triploid nutritive tissue formed after double fertilization. Its primary role is to store the food materials (starch, proteins, fats) required for the rapid growth and development of the embryo within the seed.
Q5. The nutritive tissue stored within the seed, which develops from the fusion of the male gamete and the polar nuclei, is known as the:
Show answer & explanation
Correct answer: D — Endosperm
The endosperm serves as the primary food source for the developing embryo. It develops from the fusion of the male gamete with the female gamete products.
Q6. Which procedure is commonly used to check the genetic makeup of the fetus during pregnancy?
Show answer & explanation
Correct answer: B — Amniocentesis
Amniocentesis is a diagnostic test where amniotic fluid is withdrawn for genetic analysis, used to check for chromosomal abnormalities.
Q7. Amniocentesis is a procedure primarily used for which of the following purposes?
Show answer & explanation
Correct answer: C — To detect genetic abnormalities in the fetus
Amniocentesis is a diagnostic procedure performed during pregnancy to test for chromosomal abnormalities in the fetus.
Q8. Polyembryony in seeds typically refers to the presence of:
Show answer & explanation
Correct answer: B — Multiple embryos
Polyembryony is the condition where a single ovule develops into more than one embryo, resulting in multiple embryos within the seed.
Q9. Which term describes the condition where a fruit develops without fertilization, often resulting in fleshy fruit without seeds?
Show answer & explanation
Correct answer: B — Parthenocarpy
Parthenocarpy is the development of fruit without fertilization, whereas apomixis is seed formation without meiosis.
Q10. Which technique involves transferring a fertilized ovum into the fallopian tube of the recipient?
Show answer & explanation
Correct answer: A — GIFT
GIFT (Gamete Intrafallopian Transfer) is a method where the ovum and sperm are introduced into the fallopian tube, aligning with the concept of transferring the ovum directly.
Q11. Which method of contraception involves blocking the ovum from fertilization by preventing sperm entry into the uterus?
Show answer & explanation
Correct answer: A — IUDs
Intrauterine Devices (IUDs) are a form of contraception that can prevent pregnancy by forming a barrier within the uterus, thus preventing sperm from reaching the egg.
Q12. The process of implantation of the blastocyst into the uterine wall primarily occurs in which layer of the endometrium?
Show answer & explanation
Correct answer: B — Endometrium
Implantation involves the attachment of the blastocyst to the thickened and prepared lining of the uterus, which is the endometrium.
Q13. ZIFT (ZIFT) is a type of Assisted Reproductive Technology (ART) procedure that involves transferring the embryo into which site?
Show answer & explanation
Correct answer: C — Uterus
ZIFT stands for Zygote Intra Fallopian Transfer, where the fertilized embryo (zygote) is transferred into the fallopian tube.
Q14. Spermatogenesis occurs in which part of the male reproductive system?
Show answer & explanation
Correct answer: A — Testis
Spermatogenesis, the process of sperm formation, takes place within the seminiferous tubules of the testis.
