Which of the following describes the correct order of embryogenesis?

The correct order of embryogenesis is indeed accurately described by the option provided. Understanding this process requires knowledge of the sequence of events that occur from the moment of fertilization through the development of the embryo.

Initially, fertilization occurs when the sperm and egg unite, leading to the formation of a zygote. This zygote quickly undergoes a series of rapid cell divisions known as cleavage. During cleavage, the single-celled zygote divides to form multiple smaller cells, while the overall size of the embryo remains relatively constant.

Following cleavage, the embryo reaches the blastula stage, characterized by the formation of a hollow ball of cells surrounding a fluid-filled cavity known as the blastocoel. This stage prepares the embryo for the next critical phase, which is gastrulation. During gastrulation, the cells reorganize, leading to the formation of the three germ layers: ectoderm, mesoderm, and endoderm. This is a crucial step that ultimately sets the foundation for all the different tissues and organs in the developing organism.

Finally, neurulation can occur, which involves the formation of the neural tube from the ectoderm, eventually giving rise to the central nervous system.

In summary, the correct order is fertilization
