Stages of Spermatogenesis
What process allows spermatogonia to produce more cells?
Mitosis
Site of spermatogenesis
Testes
Hormone essential for spermatogenesis
Testosterone
Hormone stimulating spermatogenesis
FSH (Follicle-stimulating hormone)
Sperm structure containing DNA
Head
What cell develops from spermatogonia?
Primary spermatocyte
Specific site inside testes where sperm develop
Seminiferous tubules
Mature sperm storage site
Epididymis
Hormone stimulating testosterone production
LH (Luteinizing hormone)
Enzyme-containing cap of sperm
Acrosome
What happens to the chromosome number during meiosis I?
It is reduced by half (from 46 to 23)
Cells that nourish developing sperm
Sertoli cells 400
Chromosome number of sperm cells
23
Hormone produced by Leydig cells
Testosterone
Structure responsible for sperm movement
Flagellum
What cells are produced after meiosis II?
Spermatids
Testosterone-producing cells
Leydig cells
Chromosome type of sperm cells
Haploid
What part of the brain controls sperm production hormones?
Hypothalamus
Organelle producing ATP in sperm
Mitochondria
What is the final stage where spermatids transform into mature sperm cells?
Spermiogenesis
Organelle-rich region supplying ATP for sperm motility
Midpiece
Division separating sister chromatids in spermatogenesis
Meiosis II
What gland releases hormones that act on the testes?
Pituitary gland
Membrane reaction allowing sperm penetration of the egg
Acrosome reaction
