cell, zygote, embryo then fetus!
Embryological development is the development of an embryo. An embryo is the beginning stages of life. Humans, other animals and some plants have the embryonic stage.
The developing cells before they are considered an embryo are called blastomeres. These are the cells that form during early stages of embryonic development through the process of cleavage.

embryonic and fetal stages
An embryo in a seed consists of the young plant in its earliest stages of development. It typically includes the stem, root, and one or more embryonic leaves (cotyledons). This structure is enclosed and protected by the seed coat.
An organism in the early stages of its development is an embryo.
Direct development involves the embryo developing into a miniature version of the adult without going through a larval stage. The stages typically involve embryonic development, growth, and maturation directly into the adult form. No larval or intermediate stages are involved in direct development.
The embryonic period are the first eight weeks of development of the child, beginning with fertilization. During this period, the embryo undergoes an amazing transformation from a single cell to a recognizably human embryo. In the mid-twentieth century, George Streeter devised a commonly used embryo classification system by dividing the embryonic period into 23 stages. The embryonic period is followed by the fetal period, which encompasses the remainder of theprenatal development.
Cleavage is important in embryonic development as it involves rapid cell divisions that increase the number of cells. This process leads to the formation of a solid ball of cells called a morula, which eventually develops into a blastocyst. Cleavage is crucial for determining the size and distribution of cells in the embryo and is essential for subsequent stages of development.
That means, the Universe in its early stages of development.
Embryonic structures are early formations that develop during the early stages of an organism's growth and development. These structures serve as the foundation for the formation of different body parts and systems as the organism matures. Studying embryonic structures can provide insights into the evolutionary history and development of different species.
