Male gametes are called? - sperm cell
Female gametes are called? - ovum or egg cell
Ovum - *largest human cell
*Consist of protective membrane that surrounds it.
*It contains yolk.
*It matures and released each month.
Sperm cell - *smallest human cell
*Consist of an oval head and a whip like tail.
*It has no yolk
*They produced 300 million or more mature sperm each day.
female sex hormones - estrogen and progesterone
male sex hormone - androgens (testosterone)
Three stages of sex cell development in female - Maturation, ovulation and fertilization/conception
Two stages of sex cell development in male - Maturation and fertilization/conception
Maturation - sex cell must undergo cell division known as meiosis or cell reduction division wherein
the number of chromosomes is halved from 46 it becomes 23.
, Ovulation - The process of releasing a mature ovum into the fallopian tube each month
Fertilization or conception - when the egg and sperm unite (usually in the fallopian tube) to begin the
formation of a baby.
Zygote - the fertilized egg; it enters a 2-week period of rapid cell division and develops into an
embryo.
Reproduction - The process by which organisms produce more organisms of their own kind.
Process of Fertilization - 1) sperm preparation,
2) sperm-egg recognition and binding,
3) sperm-egg fusion and
4) fusion of sperm and egg pronuclei and activation of the zygote.
Cilia - fallopian tube tiny hair cells
Follicle-Stimulating Hormone (FSH) - helps control the menstrual cycle and the production of eggs by
