Gamete Production and Fertilisation

• Label the male reproductive organs:

  A) bladder

  B) seminal vesicle

  C) prostate gland

  D) testis

  E) secret fluids

  F) maintain mobility and viability of sperm

  
• Label the seminiferous vesicles:

  A) interstitial cells

  B) produces testosterone

  C) sperm cell

  D) seminiferous tubules

  E) gamete mother cell/ germline cell

  
• Label the female reproductive organs:

  A) uterus

  B) oviduct

  C) ovary

  D) cervix

  E) endometrium

  F) mature ova

  G) corpus luteum

  H) progesterone

  I) immature ova

  J) follicle

  K) oestrogen

  
• A function of the interstitial cells in the testes is to produce

  testosterone
• what is the seminal vesicle function

  secrete fluids that maintain the mobility and viability of sperm
• seminiferous tubules control

  sperm production
• interstitial cells control

  secretion of testosterone
• the prostate gland controls

  secretion of thin liquid which forms part of semen
• As an ovum develops within the ovary, it is surrounded by

  follicle
• One function of the seminal vesicles is to

  produce nutrients for sperm
• what do the prostate gland and seminal vesicles do to semen

  They add sugar to semen

  They add fluid to semen

  They add enzymes to semen
• In the formation of gametes when does DNA replication occur?

  Before the start of meiosis
• Which if the following is the sequence of events following fertilisation?

  Mitosis -> implantation -> differentiation
• Semen contains substances secreted by

  Prostate (gland).
• Describe the role of the secretions from the seminal vesicles and prostate gland

  They maintain the mobility / viability of the sperm
• germline cells will contain 100% of cells containing the Y chromosome
• mature sperm cells will contain only 50% of cells containing the Y chromosome
• Name the pituitary hormone which stimulates sperm production.

  FSH.
• Name a gland which adds fluid to sperm and describe one function of this fluid.

  Gland – Prostate Gland OR Seminal vesicle.

  Function – Maintain mobility/viability of sperm.
