Human Reproductive System Questions
-
Vas deferens
-
Spermatocytes
-
Seminiferous tubules
-
None of the above
C
Correct answer
Explanation
Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of gametes, namely spermatozoa.
-
checks the entry of more sperms after fertilisation
-
checks the entry of antigens in ovum
-
represents the left out tail of the sperm
-
represents the plasma membrane of the sperm
A
Correct answer
Explanation
Fertilization membrane is the membrane that forms around a fertilised ovum and prevents penetration by additional spermatozoon.
-
Sperniatogonial cells
-
Germinal epithelial cells
-
Secondary spermatocytes
-
Primary spermatocytes
C
Correct answer
Explanation
Secondary spermatocytes are haploid whereas primary spermatocytes are diploid.
-
diploid
-
triploid
-
tetraploid
-
haploid
D
Correct answer
Explanation
Secondary spermatocytes and spermatids are haploid.
A
Correct answer
Explanation
Each testis has about 250 testicular compartments.
C
Correct answer
Explanation
Spermatogenesis begins during puberty due to the increased secretion of GnRH.
-
Gamete Interfallopian Transfer
-
Gamete Interfallopian Tubules
-
Gamete Intrafallopian Transfer
-
Gamete Intrafallopian Tubules
C
Correct answer
Explanation
GIFT stands for “Gamete Intrafallopian Transfer”.
-
ovary
-
uterus and cervix
-
the ampullary isthmic junction of the fallopian tube
-
oviducal funnels and uterus
C
Correct answer
Explanation
In rabbit, man and other placental mammals ferilization of ovum takes place in the ampullary isthmic junction of the fallopian tube.
-
coitus
-
capacitation
-
insemination
-
spermiation
B
Correct answer
Explanation
Capacitation is the process by which spermatozoa become capable of fertilizing an ovum.
-
vasectomy
-
cryptorchidism
-
impotency
-
tubectomy
B
Correct answer
Explanation
Failure of descent of testis in scrotal sacs is called cryptorchidism.
-
tail
-
head
-
acrosome
-
middle piece
D
Correct answer
Explanation
Mitochondria of a sperm occur in its middle piece.
A
Correct answer
Explanation
Antifertilizin is secreted by animal sperm before fertilisation.
A
Correct answer
Explanation
In males, spermatogenesis is induced by FSH.
D
Correct answer
Explanation
At the cellular level, reproduction refers to the formation of new cells. It can occur, if a new cell gets nucleus and nucleus contains DNA molecules. DNA is the genetic material, which is passed from one generation to another.
Thus, for reproduction, DNA material is to be duplicated. Hence, DNA is the biochemical basis of reproduction. On the contrary options (1), (2) and (3), which refer to different cells like RBC, WBC and neuron have no role in the process of reproduction.
