2.1

• Gamete


  Reproductive cell (sperm or ovum)
• Meiosis

  Cell division that produces gametes
• Gametes are haploid
• Germline stem cells are diploid
• Germline stem cells

  • Divide by mitosis to form more germline stem cells or by meiosis to produce haploid gametes
• Testes

  Male reproductive organs that produce sperm
• Testes

  • Contain seminiferous tubules that produce sperm
  • Contain interstitial cells that produce testosterone
• Interstitial cells

  Cells surrounding the seminiferous tubules that produce testosterone
• Prostate gland

  Secretes fluids to maintain sperm mobility and viability
• Seminal vesicles

  Secrete fluids to maintain sperm mobility and viability
• Ovaries

  Female reproductive organs that contain immature ova
• Follicle


  Structure surrounding and protecting the developing ovum, secretes hormones
• Zygote

  Fertilised egg
• Mature ova are released into the oviduct where they may be fertilised by sperm to form a zygote
