Which one of the following statemtents about morula in human is correct?

It has almost equal quantity of cytoplasm as an uncleaved zygote but much more DNA

It has far less cytoplasm as well as less DNA than in an uncleaved zygote

It has more or less equal quantity of cytoplasm and DNA as in uncleaved zygote

It has more cytoplasm and more DNA than an uncleaved zygote

Solution

It has more cytoplasm and more DNA than an uncleaved zygote

Cleavage divisions are mitotic division, in which the single -celled zygote is converted into a multicellular morula. But during cleavage divisions, there is no growth of resultant daughter cells/blastomeres. So, the DNA content will increase, but there is no increase or insignificant increase in amount of protoplasm.
