HUMANS

for the process of reproduction the sperms are injected into the female vagina.

when a sperm fuses with egg or ovum, FERTILLISTION take place

the nuclei of the sperm and the egg fuses to form a zygote in the fallopian tubes

the zygote divide itself repeatedly yo form a ball of cells. the cell then begin to form groups that develop into tissues and organs.

a small-tube like structure called placenta grows at the place of where embryo fix itself to uterus wall

REPORT IT IF IT IS WRONG!!!!!!
