1. Which one of the following statements with regard to embryonic development in humans is correct?

Cleavage divisions bring about considerable increase in the mass of protoplasm

In the second cleavage division, one of the two blastomeres usually divides a little sooner than the second

With more cleavage division, the resultant blastomeres become large and larger

Cleavage division results in a hollow ball of cells called morula
