1. Gametogenesis

2. Ploidy
The number of
sets of chromosomes
in a biological cell

3. Germline Cells
Cells that give rise
to gametes
(eggs and sperm)

4. Gametes
Haploid cells
that contribute
genetic material
to offspring

5. Somatic Cells
(body cells)
Diploid cells
that form the body

6. Meiosis
cell division
producing haploid cells
from diploid cells

10. Page 183

14. Oogenesis
The formation of eggs

15. ]
oogonia
diploid
germline
cells

17. Follicle
A sheath of somatic cells
that enclose oocytes

19. Polar Bodies
Small cells formed by meiosis
during the development
of an oocyte into an egg

21. Spermatogenesis
The production of sperm

25. Spermatogonia
stem cells giving rise
to spermatocytes

26. Spermatogonia
that undergo meiosis
become
Spermatocytes

28. Spermatids
haploid cells
that may be joined by
thin cytoplasmic bridges

29. Spermatids
undergo
dramatic reorganization
to become
Spermatozoa

30. the arcosome is formed,
and most of the
cytoplasm and organelles
(cytoskeleton, ER, Golgi)
are “sloughed off”

32. Seminiferous
Tubule

33. Capacitation
Further maturation
of sperm
in the female reproductive tract

34. Capacitation
The process by which
sperm become
competent to fertilize

37. Fertilization
Reinstatement of
the diploid chromosome number
