embryonic development
Embryonic development is the process by which a fertilized egg transforms into a fully formed organism. It begins with fertilization, where a sperm cell merges with an egg. This forms a zygote, which then divides multiple times, becoming a blastocyst. The blastocyst implants into the uterus, developing into three layers that will form different body systems. Over several weeks, these layers give rise to organs and tissues. Key stages include gastrulation, where layers form, and organogenesis, where organs develop. By the end of this period, the embryo is recognizable as a miniature version of the species.

Embryonic development is the process by which a fertilized egg grows and transforms into a fully formed organism. It begins with cell division, where the single cell multiplies to form a cluster called a blastocyst. This structure then implants in the uterus and develops into layers of cells that will form different organs and tissues. Over several weeks, these layers develop into recognizable body parts through a series of stages, including gastrulation and organogenesis. By the end of the embryonic stage, the basic body plan is established, setting the foundation for further growth and maturation into a viable baby.

Embryonic development is the process by which a fertilized egg transforms into a fully formed organism. This journey begins with cell division, where the single cell multiplies to form a cluster known as a blastocyst. The cells then differentiate into various types, forming the foundations of organs and systems. During this period, significant stages include gastrulation, where the basic body plan emerges, and organogenesis, where organs develop. This complex interplay of genetics and environmental factors guides the embryo's growth over weeks until it becomes recognizable as a developing fetus.
