The embryo doesn't grow larger during the stage known as cleavage.What is going on in the embryo during this process?
A)Cleavage is just the stage at which cells begin to differentiate;that is,endodermal cells start to look different from ectodermal and mesodermal cells.
B)The cells are dividing at this stage,but all the cytoplasm is being split between resulting cells without the formation of new cytoplasm.
C)Cleavage is the formation of the gastropore that is used to differentiate protostomes and deuterostomes.
D)Cleavage is the process by which the polarity of the cell is established;that is,the anterior is distinguished from the posterior.

Cleavage is the process of rapid cell division that occurs immediately after fertilization. During this stage, the zygote undergoes multiple rounds of cell division without the cell growing in size. This results in a cluster of smaller cells, each with their own nucleus, but sharing the original cytoplasm. Therefore, option B is the correct explanation of what's going on in the embryo during the stage known as cleavage. Options A, C, and D do not accurately describe cleavage.
