Multiple Choice

What is the correct sequence of stages during the cleavage period in early embryonic development?

Zygote, Morula, Blastula

Blastula, Morula, Zygote

Morula, Zygote, Blastula

Zygote, Blastula, Morula

Verified step by step guidance

Understand that cleavage is a series of rapid mitotic divisions of the zygote that leads to the formation of a multicellular structure.

Identify the initial stage: The process begins with the zygote, which is the fertilized egg cell.

Recognize the next stage: The zygote undergoes several rounds of cell division to form a solid ball of cells known as the morula.

Identify the final stage: The morula continues to divide and forms a hollow structure called the blastula.

Sequence the stages: The correct sequence of stages during the cleavage period is Zygote, Morula, Blastula.
