Web16 divisions would be 2^16; which would be 65,536 cells. That is far too many cells to fit into the size of the original zygote (cleavage happens without an overall change in size during blastulation). So to answer your question - A morula is 16 cells (some texts/teachers will say it's 32 cells). Hope that helps!
