What is the conglomerate of cells that implants in the uterus and lays the foundation for the development of the placenta and the eventual development of the fetus?

Implantation of the 5-day old embryonic stage of cells, called the blastocyst occurs. The blastocyst eventually gives rise to gastrula, and further development of the fetus proceeds.


Does mitosis allow the zygote body to grow?

The zygote is formed when two sex cells join to become haploid. It is at this stage that the zygote begins to split and make more cells. It keeps doing this for 5 days until it is called a blastocyst, which is a ball of cells. After this point, the blastocyst is called an embryo or fetus. The embro continues to make cells which eventually become specialised, like skin cells and muscle cells. It doesn't have anything to do with conservation of mass, just splitting and making thousands of new cells until the zygote becomes a baby.

When is an egg considered an embryo?

It takes 1-3 days for a egg to get fertilized and then it's called a zygote. It then takes 3-5 days until the zygote enters the uterus. In the uterus, the cells continue to divide and becomes blastocyst which attaches to the lining of the uterus. This is called implantation and is completed by day 9-10. The next step it's a embryo.

How many totipotent cells does a 5 week old embryo have?

Embryonic stem cells refer to pluripotent cells that are generally derived from the inner cell mass of blastocysts (day 5). Stem cells have been derived from gonadal ridges and mesenteries (3200 to 4000) extracted from aborted five-to-nine week old human embryos.
