8 cell stage
The development at an early stage for humans is called embryonic development, for pets is called embryonic or fetal development, and for petunias is called seed germination and seedling development.
The embryonic stage in which cell migration and differentiation occurs is known as gastrulation. During this process, cells undergo extensive reorganization to form the three germ layers - ectoderm, mesoderm, and endoderm, which give rise to various tissues and organs in the developing embryo.
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 fetal stage of development begins at the end of the embryonic stage, typically around 8 weeks after fertilization. During this stage, the organs and tissues continue to grow and develop in preparation for birth.
Pre-embryonic development is associated with processes including fertilization, cleavage, and formation of the blastocyst. During this stage, the zygote undergoes division and differentiation to form the blastocyst that will later implant into the uterine wall for further development into an embryo.
A fetus develops a nervous system during the embryonic stage of development, which occurs around the 3rd to 8th week of pregnancy.

Embryonic refers to the earliest stage of development of an organism, particularly in reference to an embryo before it is fully developed. It can also refer to anything in a primitive or rudimentary stage of development.
hollow ball of cells formed after the morula stage. It is characterized by a fluid-filled cavity called the blastocoel surrounded by a layer of cells called the blastoderm. The blastula is an early stage in embryonic development before gastrulation occurs.
Before the fetal stage is the embryonic stage. The embryo develops into the fetus.
The period of prenatal development that occurs 2 to 8 weeks after conception is known as the embryonic period. This stage is crucial for the formation of major organs and structures in the developing embryo, and any disruptions during this period can have long-lasting effects on the baby's health.
During the embryonic stage, which occurs from the 3rd to the 8th week of pregnancy, nearly all basic organs are formed. This is a critical period for development, as the foundation is laid for the baby's major body systems and structures.
Prenatal development occurs in three main stages: the germinal stage (first two weeks after conception), the embryonic stage (weeks 3-8), and the fetal stage (weeks 9-birth). During these stages, the fertilized egg undergoes cell division, differentiation, and organ formation, leading to the development of a fetus.
