Gametogenesis

  1. 1. Gametogenesis
  2. 2. Ploidy The number of sets of chromosomes in a biological cell
  3. 3. Germline Cells Cells that give rise to gametes (eggs and sperm)
  4. 4. Gametes Haploid cells that contribute genetic material to offspring
  5. 5. Somatic Cells(body cells) Diploid cells that form the body
  6. 6. Meiosis cell division producing haploid cells from diploid cells
  7. 7. Page 183
  8. 8. Oogenesis The formation of eggs
  9. 9. ]oogonia diploid germline cells
  10. 10. Follicle A sheath of somatic cells that enclose oocytes
  11. 11. Polar Bodies Small cells formed by meiosis during the development of an oocyte into an egg
  12. 12. Spermatogenesis The production of sperm
  13. 13. Spermatogonia stem cells giving rise to spermatocytes
  14. 14. Spermatogonia that undergo meiosis becomeSpermatocytes
  15. 15. Spermatids haploid cells that may be joined by thin cytoplasmic bridges
  16. 16. Spermatids undergo dramatic reorganization to becomeSpermatozoa
  17. 17. the arcosome is formed, and most of thecytoplasm and organelles (cytoskeleton, ER, Golgi) are “sloughed off”
  18. 18. SeminiferousTubule
  19. 19. Capacitation Further maturation of sperm in the female reproductive tract
  20. 20. Capacitation The process by which sperm become competent to fertilize
  21. 21. Fertilization Reinstatement of the diploid chromosome number
