Explanation:

The morula stage occurs during embryonic development. It is formed through a series of cell divisions (cleavages) from a single - celled zygote. After several rounds of mitotic divisions (each division approximately doubling the number of cells), when the embryo reaches a stage with 16 cells, it is called a morula.
