GAMETOGENESIS Flashcards
PROCESS OF DEVELOPMENT AND MATURATION OF SEX CELL GAMETES
GAMETOGENESIS
MATUYRE REPRODUCTIVE CELLS CAPABLE OF FERTILIZATION
GAMETES
GIVE ME 3 OF THE FUNCTION OF GAMETOGENESIS?
1.TO SURVIVE in environment quiet different from the gonad
2. TO RECOGNIZE homologous celss of other gender and participate in event related to fertilization
3. TO PROVIDE sufficient genetic and cytoplasmic materials to support development of a new organism
duration of maturation in female
BEFORE BIRTH - SEXUAL MATURITY- LOSS OF FERTILITY
duration of maturation in male
FROM BIRTH - SEXUAL MATURITY - DEATH
in spermatogenesis the nucleus of spermatids become the?
HEAD
the golgi becomes the ?
ACROSOME
cytoplasm becomes the?
enevlope surrounding the head, middle piece and tail
mitochondria becomes the?
spiral filament in the middle piece
Centrosome becomes the?
motile or sperm tail
transformation of spermatids to spermatozoa is embedded in the cytoplasm of ?
SERTOLI CELLS in the testes
inside this tubules is where the sperm cells are actually form through.
SEMINIFEROUS TUBULES
In spermatogenesis and oogenesis premordial germ cells Q1.migrate to? and Q2. is ?
A1. Embryonic gonad
A2. WITHOUT sex or indifferent stage
in spermatogenesis this stages is in sexual differentiation, WHICH undergo mitosis many times to produce daughter spermatogonia.
SPERMATOGONIA
in this stage it enter 1st phase or (meiosis 1), also known as reduction division, increased production of testosterone
daughter spermatogonia
