ULL BIOL 110 Final Exam Study Guide | Biology Review, Key Concepts & Practice
Questions
What is Budding? - ANS ✔✔A portion of the parent pinches off to form the offspring
What is Regeneration (fragmentation)? - ANS ✔✔A complete organism can be formed from a
piece of the parent organism
What is Parthenogenesis? - ANS ✔✔Offspring develop from unfertilized eggs
What is a zygote? - ANS ✔✔A zygote is a fertilized egg that forms when two gametes are fused
together.
What is a gamete? - ANS ✔✔A male gamete is sperm and a female gamete is an egg.
Are gametes haploid or diploid? - ANS ✔✔Gametes are haploid.
What type of internal fertilization results in fertilized eggs being laid outside the female's body?
- ANS ✔✔Oviparity
Why are testicles suspended away from the body of the male? - ANS ✔✔Testicles are
suspended away from the male body because sperm does not develop at body temperature. It
develops 2-3 degrees cooler
What is cryptorchidism? - ANS ✔✔Failure of both testicles to descend into the scrotum.
What cells in the testicles produce testosterone? - ANS ✔✔Interstitial cells(Leydig cells)
, Where in the testicles is sperm produced? - ANS ✔✔Seminiferous tubules
Why can males continue to make sperm throughout their lifetime? - ANS ✔✔A stem cell
population always remains so males are capable of producing sperm throughout their life.
Can females continue to make oocytes throughout their lifetime? Why or why not? - ANS
✔✔Females cannot make new oocytes throughout their lifetime. In females all of the stem cells
are turned into oocytes. When she is born, she can no longer make new oocytes.
What is the function of the epididymis? - ANS ✔✔The epididymis is where the sperm completes
its maturation process and is stored until ejaculation.
What are three functions of accessory sex gland secretions? - ANS ✔✔-Adds volume to
ejaculate (For better "propulsion")
-Provides nutrients for the sperm
-Adds buffers to counteract acidity of female genital tract
-Adds enzymes that help the sperm function and increase mobility
What is the difference between penile erection and ejaculation? - ANS ✔✔Penile Erection is
when the penis stiffens to prepare for ejaculation. Ejaculation is the release of semen out of the
urethra.
Which process is under parasympathetic nervous system control? - ANS ✔✔Penile erection
What is the function of the acrosome of a sperm? - ANS ✔✔The acrosome helps penetrate the
oocyte wall.
What is the function of luteinizing hormones in males? - ANS ✔✔Stimulates Sertoli cells to help
nourish the sperm
