Q. Which one of the following statements about morula in humans is correct
A) It has almost equal quantity of cytoplasm as an uncleaved zygote but much more DNA
B) It has far less cytoplasm as well as lessDNA than in an uncleaved zygote
C) It has more or less equal quantity of cytoplasm and DNA as in uncleaved zygote
D) It has more cytoplasm and more DNA than an uncleaved zygote
Explanation
Cleavage divisions are mitotic division, in which the single celled zygote is connected into a multicellular morula. But during cleavage division, there is no growth of resultant daughter cell/blastomeres. So, the DNA content will increase, but there is no increase or insignificant increase in amount of protoplasm.
