Answer:
Cleavage, in embryology, in the first few cell divisions of the zygote. Initially, the zygote separates into the longitudinal axis. The second division is also longitudinal but at 90 degrees on the first plane. The process produces a multicellular embryo. It is an assembling process that divides the seed into developmental regions. Zygote cytoplasm includes chemicals that control gene expression.
Gastrulation is characterized as an early embryonic phase in which the embryo is converted from a one-dimensional layer of epithelial cells to a multilayer, multidimensional structure called the gastrula.
Organogenesis is a process of embryonic development that occurs at the end of gastrulation and lasts until birth. During organogenesis, the three germ layers formed by gastrulation (ectoderm, endoderm, and mesoderm) form the internal organs.

Earth is a beautiful planet that revolves around a star called Sun, which is located in one of the arms of our Milky Way Galaxy. It is the only planet known to support life in the Solar System. Humans are the most intelligent civilization on this planet. It's blue when seen from space. Recently, Earth 29 spacecraft was able to land on this planet, after 28 unsuccessful landings of Earth series of spacecrafts. We were able to learn many things about humans, most important of these was the most spoken language of them, which they call English. According to experts, humans are not yet ready to know about our existence. It can take about 1 or 2 more centuries, until they are ready to know about us.
