ALBERTA BIOLOGY 30 REPRODUCTION AND
DEVELOPMENT QUESTIONS AND ANSWERS
What is the difference between primary and secondary sex characteristics? - CORRECT
ANSWER✅✅✅primary = direct role in reproduction (gonads)
secondary = features that distinguish the two sexes; develop at puberty
What is the process of creating a zygote called? How many chromosomes does it have? -
CORRECT ANSWER✅✅✅fertilization; 46 chromosomes
What kinds of sex chromosomes can a sperm contribute? An egg? - CORRECT
ANSWER✅✅✅sperm = X or Y
egg = only X
What is the function of the scrotum? - CORRECT ANSWER✅✅✅highly elastic skin; holds
testes outside of body for optimal sperm production
What is the function of the seminiferous tubules? Where are they found? - CORRECT
ANSWER✅✅✅produce sperm in response to FSH; found in testes
What is the function of the interstitial cells? Where are they found? - CORRECT
ANSWER✅✅✅produce testosterone in response to LH; found in testes (between sem.
tubules)
What is the function of the epididymis? - CORRECT ANSWER✅✅✅site of sperm
maturation and storage
What is the function of the vas deferens? - CORRECT ANSWER✅✅✅tubes; carry sperm
from epididymis to urethra; cut and tied during a vasectomy
, What is the function of the Seminal vesicles? - CORRECT ANSWER✅✅✅produce Sugar
which nourishes sperm & increases motility; produces prostaglandins which stimulate uterine
contractions (aids the movement of sperm cells)
What is the function of the ejactulatory duct? - CORRECT ANSWER✅✅✅regulates release
of sperm into urethra
What is the function of the prostate gland? - CORRECT ANSWER✅✅✅produces basic
mucus to protect sperm from acidity of vagina
What is the function of the Cowper's gland? - CORRECT ANSWER✅✅✅produces basic
mucus that Cleans the urethra of acidic urine
What is the composition of semen? - CORRECT ANSWER✅✅✅sperm, sugar (fructose),
basic mucus, prostaglandins
Name the glands that contribute to the composition of semen. - CORRECT
ANSWER✅✅✅testes, seminal vesicles, prostate gland, Cowper's gland
Which gland contributes a cellular component of semen? - CORRECT ANSWER✅✅✅only
the testes
What is spermatogenesis? What are the products? - CORRECT ANSWER✅✅✅production
of sperm in response to FSH; meiosis that occurs in the sem. tubules; produces four equal sized
daughter cells
What is the function of the Sertoli cells? - CORRECT ANSWER✅✅✅nourish/protect the
sperm; have FSH receptors; make inhibin (prevents spermatogenesis during childhood) *not
curricular*
Name the three parts of sperm and their functions. - CORRECT ANSWER✅✅✅head =
contains acrosome with digestive enzymes to help penetrate the egg & 23 chromosomes
