Zygote
When the sperm meets the ovum and goes into the zygote .
zygote stage, embryonic stage,and fetal stage
embryotic stage
Pre-embryonic :begins with fertilization and encompasses the first 2 weeks thereafter. Cellular division and implantation occurs this stage of development. Embryonic : this stage last from the end of the 2nd week after Fertilization until the end of the 8th Weeks is also the time when the women misses her first menstrual period. Fetal: this stage is from the beginning of the 9th week after fertilization and continues until birth. At this time, the developing human is referred to as a fetus.
Sperm have various stage. First and Second Stage. Both stage is capable of producing fertilization depending on the cycle or the period of the female. First stage: at this stage the male is not aware of that, Second stage: it's the stage we are well of. That is, if the female is not in safe period, first stage can make her pregnant as well.
It is the main stage of mitosis
the gametophyte stage begins with meiosis and the sporophyte stage begins with fertilization.
They meet to form a zygote which is the first stage of maturity of a human. Hope this helps ;;; ;;;;;;;; ;;; ;;; ;;; ;;; ;;; ;;; ;;; ;;; ;;;;;;;;; ;;;;;;;;
Well...first of all it is called fertilization. The actual baby at this very early stage is called a zygote.
fertilization begins and zygote plants itself onto the uterus
The frog has three distinct stages of development in its life cycle.the first stage is the laying of the ova and the fertilization stage in the water called the spawning stage.The second stage is the tadpole stage where the eggs hatch and the tiny tadpoles swing in water to develop limbs .The final stage is the terrestial stage when the frog leaves the water .
