trophoblast
The group of approximately 100 cells that forms from a fertilized egg is called a blastocyst. It is the stage of development that precedes implantation in the uterus during early embryonic development.
The outer layer of the blastocyst will become the trophoblast, which later develops into the placenta. The inner cell mass of the blastocyst will give rise to the embryo and eventually the fetus.
The blastocyst cells that do not become part of the human body form the placenta and other supporting tissues necessary for fetal development. These cells contribute to the formation of structures that facilitate the exchange of nutrients and waste between the mother and the developing embryo.
The inner cell mass of the blastocyst will undergo gastrulation and form the embryo. This inner cell mass consists of pluripotent cells that will give rise to the various tissues and organs of the developing embryo.
The male part that produces pollen is the Stamen, The female part with pollen receptors, is the stigma.

Yes. It is part of the development of the embryo.
The placenta is developed during pregnancy from the implantation of a blastocyst. The blastocyst creates the outer layer of the placenta. This continues to developed into two more portions and then develops an outer protective layer. The placenta grows throughout the entire pregnancy.
Yes, trophoblastic nutrition occurs during the preembryonic stage of development. This process involves the trophoblast cells forming the outer layer of the blastocyst, which helps facilitate the absorption of nutrients from the maternal uterine lining to support early embryonic growth before implantation.
The blastocyst cells that do not become part of the human body form the placenta and other supporting tissues necessary for fetal development. These cells contribute to the formation of structures that facilitate the exchange of nutrients and waste between the mother and the developing embryo.

blastocyst The most versatile stem cells occur earliest in life. As a fertilized human egg divides, it first becomes a solid ball of cells, the morula. Next, about five days after fertilization, it becomes a hollow ball, the blastocyst. The cells of the outer layer of the blastocyst eventually form part of the placenta.
