Quizplus · Accepted Answer

The correct sequence of preembryonic structures is zygote, morula, blastocyst. The zygote forms after fertilization of the egg by the sperm. The zygote then undergoes rapid divisions to form a solid ball of cells called the morula. The morula then continues to divide and differentiate into a fluid-filled structure called the blastocyst.
