ZYGOTE
After a female egg is fertilized, the resulting one-celled
organism becomes known as a zygote. Once the egg is fertilized, the zygote
begins a two-week period of rapid cell division and will eventually become an
embryo. The zygote divides through a process known as mitosis, in which each
cell doubles by dividing into two cells. This two-week stage is known as the
germinal period of development and covers the time of conception to the
implantation of the embryo in the uterus.
In most cases, each male and female sex cell contain 23 chromosomes.
When these two haploid cells join, they form a single diploid cell that
contains a total of 46 chromosomes. The zygote begins a journey down the
fallopian tube to the uterus where it must implant in the lining in order to
obtain the nourishment it needs to grow and survive.
The period of the zygote lasts for about four days. Around the
fifth day, the mass of cells becomes known as a blast cyst. The germinal period
will last for fourteen days, after which the embryonic period will begin. The
second period of development lasts from two weeks after conception through the
eighth week, during which time the organism is known as an embryo. At the ninth
week post-conception, the fetal period begins. From this point until birth, the
organism will be known as a fetus.
