Study Notes

Asexual Reproduction

  • Does not require union
  • Binary Fission: Cell divides into two genetically identical cells without exchanging genetic material
  • Budding: New organism develops from a bud (outgrowth) on the parent, receiving nutrients until it detaches
  • Fragmentation: Organism splits into fragments, each developing into a new, complete organism
  • Spore Formation: Production of spores

Sexual Reproduction

  • Requires union
  • 46 chromosomes (23 from each parent)
  • Sex cells (sperm and egg)
  • Somatic cells (research needed)
  • Secondary sex organs (essential to reproduction, male: ducts, glands, penis; female: uterine tubes, uterus, vagina)

Male Reproductive System

  • Composed of two testes, glands, and an organ that transfers sperm
  • Testes: Oval organs (4-7 cm long, 20-25 mL volume), within the scrotum. Produce sperm cells from germ cells in seminiferous tubules. Secretes testosterone.
  • Penis: Transfers sperm to the female's body

Additional Information

  • Various aspects about the different components of the male reproductive system, including their structures and functions, are included in the provided diagrams.
  • Additional details regarding the processes, structures and functions of the female reproductive system are included
  • Details on various types of diseases are included as well as relevant treatments and symptoms
